2. Introduction This chapter introduces ConnectPort LTS products, types of supported connections and data paths, and the interface options available for configuration, monitoring, and administration tasks. Important Safety Information To avoid contact with electrical current: Never install electrical wiring during an electrical storm. Never install an Ethernet connection in wet locations unless that connector is specifically designed for wet locations.
The ConnectPort LTS Family ConnectPort LTS (Linux Terminal Server) products provide serial over Ethernet connectivity for applications today and into the future. They support IPv4 and IPv6 Ethernet protocols. The ConnectPort LTS MEI product is the same size as the ConnectPort LTS (RS-232 only version) and is the fastest multi-port device with a Multiple Electrical Interface (MEI) in the industry. Features This is an overview of key product features.
Quick reference for configuring features This guide primarily focuses on configuration, monitoring, and administration tasks from the web interface. This table provides a quick reference for configuring features and performing device tasks, and where to find the features and settings in the web interface and this guide. Some features are configurable from the command line interface only. In those cases, the commands that configure the feature are noted.

Hardware and network interface features For detailed hardware specifications and network interface information, go to: http://www.digi.com/products/serialservers/connectportlts#specs. See also the data sheet for your Digi product. Configurable network services Access to network services can be enabled and disabled. This means that a device’s use of network services can be restricted to those strictly needed by the device. To improve device security, non-secure services, such as Telnet, can be disabled.
IP protocol support All ConnectPort LTS products include a robust on-board TCP/IP stack with a built-in web server. Supported protocols include, unless otherwise noted: Transmission Control Protocol (TCP) User Datagram Protocol (UDP) Dynamic Host Configuration Protocol (DHCP) Simple Network Management Protocol (SNMP) Secure Sockets Layer (SSL)/Transport Layer Security (TLS) Telnet Com Port Control Option (Telnet).
Following is an overview of some of the services provided by these protocols. Serial data communication over TCP and UDP ConnectPort LTS products support serial data communication over TCP and UDP. Key features include: Serial data communication over TCP, also known as autoconnect and tcpserial can automatically perform the following functions: – Establish bidirectional TCP connections, known as autoconnections, between the serial device and a server or other network device.
Auto-IP Auto-IP is a protocol that will automatically assign an IP address from a reserved pool of standard Auto-IP addresses to the computer on which it is installed. ConnectPort LTS is set to obtain its IP address automatically from a DHCP server. But if the DHCP server is unavailable or nonexistent, Auto-IP will assign the device an IP address. For further details, see "IP address assignment alternatives.
Secure Sockets Layer (SSL)/Transport Layer Security (TLS) Secure Sockets Layer (SSL)/Transport Layer Security (TLS) are used to provide authentication and encryption for ConnectPort LTS products. For more information, see ”Security features.
Point-to-Point Protocol (PPP) The Point-to-Point Protocol (PPP) transports multi-protocol packets over point-to-point links. PPP encapsulates the data packet, allows the server to inform the dial-up client of its IP address (or client to request the IP address), authenticates the exchange, negotiates multiple protocols, and reassembles the data packet for network communication.
IP address assignment alternatives There are several ways to assign an IP address to a ConnectPort LTS product: Static IP: Assign a specific IP address to a device, through the Digi Device Discovery Utility, the web interface, LCD, Digi Device Discovery tool, or the command-line interface. Using Dynamic Host Configuration Protocol (DHCP). Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating the configuration of computers that use TCP/IP.
RealPort software ConnectPort LTS products use the patented RealPort COM/TTY port redirection for Microsoft Windows, UNIX, and Linux environments. RealPort software provides a virtual connection to serial devices, no matter where they reside on the network. The software is installed directly on the host PC and allows applications to talk to devices across a network as though the devices were directly attached to the host. Actually, the devices are connected to a Digi device somewhere on the network.
Alarms ConnectPort LTS products can be configured to issue alarms, in the form of email message or SNMP traps, when certain device events occur. These events include certain data patterns being detected in the data stream. Receiving alarms about these conditions provides the advantage of notifications being issued when events occur, rather than having to monitor the device on an ongoing basis to determine whether these events have occurred. For more information on configuring alarms, see "Alarms.
Security features Security-related features in ConnectPort LTS products include: Secure access and authentication: – One password, one permission level. – Can issue passwords to device users. – Can selectively enable and disable network services such as ADDP, RealPort, Encrypted RealPort, HTTP/HTTPS, LPD, Remote Login, Remote Shell, SNMP, Telnet and Secure Shell (SSH). – Can control access to inbound ports. – Secure sites for configuration: HTML pages for configuration have appropriate security.
Configuration management Once a ConnectPort LTS product is configured and running, configuration-management tasks need to be periodically performed, such as: Upgrading firmware Copying configurations to and from a remote host Software and factory resets Rebooting the device Memory management File management For more information on these configuration-management tasks, see Chapter 4, "Administration tasks.
Supported connections and data paths ConnectPort LTS products allow for several kinds of connections and paths for data flow between the ConnectPort LTS product and other entities. These connections can be grouped into two main categories: Network services, in which a remote entity initiates a connection to a ConnectPort LTS product. Network/serial clients, in which a ConnectPort LTS product initiates a network connection or opens a serial port for communication.
Reverse SSH: An SSH connection is made to a ConnectPort LTS product, in which data is passed transparently between the SSH connection and a named serial port. Network services associated with serial ports in general RealPort: A single TCP connection manages (potentially) multiple serial ports. Modem emulation, also known as pseudo-modem (pool): A TCP connection to the “pool” port is interpreted as an incoming call to an available pseudo-modem in the “pool” of available port numbers.
Network/serial clients A network/serial client connection is one in which a ConnectPort LTS product initiates a network connection or opens a serial port for communication.
Command-line interface (CLI)-based client connections Command-line interface based client connections are available for use once a user has established a session with the ConnectPort LTS product CLI. CLI-based client connections include: telnet: A connection is made to a remote entity using the Telnet protocol. bash: The “bash” command provides access to the Linux bash shell. rlogin: A connection is made to a remote entity using the Rlogin protocol.
Configuration capabilities and interfaces This is an overview of the configuration capabilities and interfaces for ConnectPort LTS products; Chapter 2, "Configuration," covers them in more detail. Configuration capabilities Device configuration involves setting values and enabling features for such areas as: Network configuration: Specifying the device IP address and IP settings, network-service settings, and advanced network settings.
Digi Device Discovery utility The Digi Device Discovery utility locates Digi devices on a network and allows for opening the web interface for discovered devices, configuring network settings, and rebooting the device.
Advantages of the Digi Device Discovery utility are: It quickly locates Digi devices and basic device information, such as the device address, firmware revision, and whether it has been configured. ADDP runs on any operating system that can send multicast IP packets to a network. It sends out a User Datagram Protocol (UDP) multicast packet to all devices on the network. Devices supporting ADDP reply to this UDP multicast with their configuration information.
The Web interface A web interface is provided as an easy way to configure and monitor ConnectPort LTS products. Configurable features are grouped into several categories. These categories vary by product; examples include Network, Serial Port, Alarms, System, and Users. Most of the configurable features are arranged by most basic settings on a page, with associated and advanced settings accessible from that page.
Command-line interface ConnectPort LTS products can be configured by issuing commands from the command line. The command-line interface allows communication directly without a graphical interface. For example, the following is a command issued from the command line to set general serial configuration options: #> set serial port=1-32 baudrate=9600 flowcontrol=hardware Advantages of the command-line interface include: Flexibility.
Simple Network Management Protocol (SNMP) Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network devices. The SNMP architecture enables a network administrator to manage nodes--servers, workstations, routers, switches, hubs, etc.--on an IP network; manage network performance, find and solve network problems, and plan for network growth. ConnectPort LTS supports SNMP Versions 1, 2 and 3. Advantages of SNMP include: SNMP is easy to implement in extensive networks.
Standard MIBs supported The standard MIBs supported in ConnectPort LTS products are: MIB-II (RFC 1213) This is a MIB for managing a TCP/IP network. It is an update of the original MIB, now called MIB-I. MIB-II contains variable definitions that describe the most basic information needed to manage a TCP/IP network.
Monitoring capabilities and interfaces There are several capabilities and interfaces for monitoring ConnectPort LTS products and managing their connections; these are covered in more detail in Chapter 3, "Monitor and manage Digi devices.” Monitoring ConnectPort LTS products includes such tasks as checking device status, viewing information on a device, checking runtime state, viewing serial port operations, and reviewing network statistics, and managing their connections.
LCD panel The LCD panel can be used to perform several monitoring tasks. For more information, see LCD interface: configuration, monitoring, and diagnostics’ on page 131.
3. Configuration This chapter describes how to configure a ConnectPort LTS product. It covers these topics: "Alternate methods for assigning an IP address". "Configuration through the web interface". "Configuration through the command line". "Configuration through Simple Network Management Protocol (SNMP)". "Batch capabilities for configuring multiple devices". The primary focus of this chapter is on configuring ConnectPort LTS products through the web interface.
Configure an IP address from the command-line interface The set network command configures an IP address from the command line. Include the following parameters: index=(1-4) : Ethernet interface index number ip_v4=device ip: The IP v4 address for the device. gateway_v4=gateway: The network gateway IP v4 address. submask_v4=device submask: The device subnet mask for IP v4 address. mode_v4=(none|static|dhcp): The configuration mode of IP v4 address.

Here is the home page for the ConnectPort LTS: The Home page The left side of the Home page has a menu of choices that display pages for configuration, management, and administration tasks, and to log out of the web interface. This chapter focuses on the choices under Configuration and Application.
Home page display differences for multiple-power-supply models For ConnectPort LTS models with multiple power supplies, such as the ConnectPort LTS 16 MEI 2AC, the Home page displays a power failure message above the menu if either of the power supplies is unplugged.
Configuration pages The choices under Configuration in the menu display pages for configuring settings for various features, such as network settings, and serial port settings. Some of the configuration settings are organized on sets of linked screens. For example, the Network Configuration screen initially displays the IP Settings, and provides links to Network Services Settings, Advanced Settings, and other network settings appropriate to the ConnectPort LTS product.
Restore the ConnectPort LTS product to factory defaults The device configuration can be reset to factory defaults as needed during the configuration process. See "Restore a device configuration to factory defaults.” Online help Online help is available for all screens of the web interface, and for common configuration and administration tasks. There is also tutorial available on the Home page.
Change the IP address from the web interface, as needed Normally, IP addresses are assigned to ConnectPort LTS products through DHCP. This procedure assumes that the ConnectPort LTS product already has an IP address and you simply want to change it. 1. Open a web browser and enter the current IP address for the ConnectPort LTS product in the URL address bar. 2. If security is enabled for the ConnectPort LTS product, a login prompt is displayed. Enter the user name and password for the device.
Network configuration settings The Network configuration pages include: Ethernet IP settings: For viewing IP address settings and changing as needed. Network Services settings: Enable and disables access to various network services, such as ADDP, RealPort and Encrypted RealPort, Telnet, SSH, HTTP/HTTPS, and other services. Advanced Network Settings: Configures the Ethernet Interface speed and mode, TCP/IP settings, TCP keep-alive settings, and DHCP settings.
Ethernet IP settings The Ethernet IP settings configure how the IP address of the ConnectPort LTS product is obtained, either by DHCP or by using a static IP address, subnet mask, default gateway. In addition, this page shows IP addresses of the primary and secondary Domain Name System (DNS) server for the ConnectPort LTS product. For more information about these settings as assigned and used in your organization, contact your network administrator.
IPv6: Internet Protocol version 6 configuration. − Do not use this interface: Choose this option if you do not want to enable IPv6 address on this Ethernet interface. − Auto configuration: Choose this option if you want to set IPv6 address through the stateless autoconfiguration protocol. − Obtain an IP address automatically using DHCP: Choose this option if you want to set IPv6 address through DHCPv6.
Basic Network Services Settings The Basic Network Services page shows a set of common network services that are available for ConnectPort LTS products, and the network port on which the service is running. Common network services can be enabled and disabled, and the TCP port on which the network service listens can be configured. Disabling services may be done for security purposes. That is, certain services can be disabled so the device runs only those services specifically needed.
Supported basic network services and their default network port numbers In Digi devices that have multiple serial ports, the network port number defaults for various services are set based on the following formula: base network port number + serial port number The default base assumed is 2000. For example, the Telnet Passthrough service is set to network port 2001 for serial port 1, 2002 for serial port 2, 2003 for serial port 3, etc.
The table shows network services, services provided, and the default network port number for each service. Service Services provided Default network port number Device Discovery, also known as Advanced Digi Discovery Protocol (ADDP) Discovery of Digi devices on a network. Disabling this service disables use of the Digi Device Discovery utility to locate the device. The network port number for ADDP cannot be changed from its default.
Service Services provided Default network port number services such as traps and device information are not used. Telnet Server Allows users an interactive Telnet session to the ConnectPort LTS product command-line interface. If disabled, users cannot Telnet to the device. 23 Telnet Passthrough Allows a Telnet connection directly to the serial port, often referred to as reverse Telnet.
Advanced Network Services Settings The Advanced Network Services page shows a set of specific network services that are available for ConnectPort LTS products, and the related settings for the service. Web Settings: − Login timeout: Idle timeout settings for Web server. SMTP Settings: − Enable: Enable or disable the SMTP server − SMTP server name: IP address or DNS name of the SMTP server. − SMTP with authentication: Choose this option if your SMTP server can be accessed after authentication.
Samba Settings : − Enable: Enable or disable the Samba service. − Samba server name: IP address or DNS name of the Samba server. − Mounting on path Samba server: Full path name of mounting point on the Samba server. − Samba timeout: Interval in seconds before disconnecting Samba connection when the Samba server is not responding. − Samba mount retrying interval: Interval in seconds when Samba remounting is tried after disconnecting the Samba connection.
Socket tunnel settings A Socket Tunnel can be used to connect two network devices: one on the ConnectPort LTS product’s local network and the other on the remote network. This is especially useful for providing SSL data protection when the local devices do not support the SSL protocol. One of the endpoint devices is configured to initiate the socket tunnel. The tunnel is initiated when that device opens a TCP socket to the ConnectPort LTS product on the configured port number.
Advanced network settings The Advanced Network Settings are used to further define the network interface, including: Host name: The Host name to be placed in the DHCP Option 12 field. This is an optional setting which is only used when DHCP is enabled. Enable Auto IP address assignment: Whether Auto-IP address assignment is enabled or disabled.
Serial port settings Use the Serial Port Configuration page to establish a port profile for the serial port of the ConnectPort LTS product. This page includes the currently selected port profile for the serial port, detailed configuration settings for the serial port, dependent on the port profile selected, and links to Basic Serial Settings and Advanced Serial Settings.
RealPort profile The RealPort profile maps a COM or TTY port to a serial port. This profile configures a ConnectPort LTS product to create a virtual COM port on a PC, known as COM Port Redirection. The PC applications send data to this virtual COM port and RealPort sends the data across the network to the ConnectPort LTS product. Data is routed to the serial device connected to the ConnectPort LTS product serial port. The network is transparent to both the application and the serial device.
TCP Sockets profile The TCP Sockets profile allows serial devices to communicate over a TCP network. The TCP Server allows other network devices to initiate a TCP connection to the serial device attached to the serial port of the ConnectPort LTS product. Automatic TCP connections (autoconnection) The TCP Client allows the ConnectPort LTS product to automatically establish a TCP connection to an application or a network, known as autoconnection.
UDP Sockets profile The UDP Sockets profile allows serial devices to communicate using UDP. The UDP Server configuration allows the serial port to receive data from one or more systems or devices on the network. The UDP Client configuration allows the automatic distribution of serial data from one host to many devices at the same time using UDP sockets. The port numbering conventions shown in the TCP Sockets Profile also apply to UDP sockets.
Modem Emulation profile The Modem Emulation profile allows a Digi device to send and receive modem responses to the serial device over the Ethernet instead of PSTN (Public Switched Telephone Network). This profile allows maintaining the current software application but using it over a less-expensive Ethernet network. The commands that can be issued in a modem-emulation configuration are described in the ConnectPort LTS Command Reference.
Local Configuration profile The Local Configuration profile allows access to the command-line interface when connecting from a serial terminal. Custom Profile The Custom port profile displays all serial-port settings, which can be changed as needed. Use the Custom profile only if the use of the serial port does not fit into any of the predefined port profiles, for example, if network connections involve a mix of TCP and UDP sockets.
Basic serial settings After selecting a port profile, the profile settings are displayed. Choose the appropriate features for your environment. Here are brief descriptions of the fields in the Basic Serial Settings; see the online help for detailed information about each setting. The Description field specifies an optional character string for the port which can be used to identify the device connected to the port.
Advanced serial settings The advanced serial settings further define the serial interface, including whether port buffering (also known as port logging), or RTS Toggle are enabled, as general serial interface options. You can also define how specific aspects of TCP and UDP serial communications should operate, including timeouts and whether a socket ID is sent.
TCP settings The TCP Settings are displayed only when the current serial port is configured with the TCP Sockets or the Custom Profile. The settings are as follows: Send Socket ID: Include an optional identifier string with the data sent over the network. The Socket ID can be 1 to 256 ASCII characters.
− Send after the following number of idle: Send the data after the specified number of milliseconds has passed with no additional data received on the serial port. This can be 1 to 65,535 milliseconds. − Send after the following number of bytes: Send the data after the specified number of bytes has been received on the serial port. This can be 1 to 65,535 bytes. Close connection after the following number of idle seconds: Enable to close an idle connection.
Authentication Settings The authentication settings set the authentication method and related settings. The ConnectPort LTS supports following authentication methods. None: When selected, user can access the serial port without authentication. This is the factory default setting. Local: When selected, the user who registered the local database of ConnectPort LTS through user configuration can only access the serial port.
For Radius authentication, the following settings are required. − Primary authentication server: The IP address or DNS name of authentication server. This option is compulsory to use the remote authentication method. If this server is down or busy, the authentication query is sent to the secondary server, if specified. − Secondary authentication server: The IP address or DNS name of the secondary authentication server. This option is complementary.
LDAP: When selected, user who registered the database of LDAP server specified can only access the serial port. There are several categories of LDAP authentication Methods: − LDAP server: The user authentication performed only through the LDAP server. − LDAP server - Local: The user authentication performed through the LDAP server first. If succeeded, user can access the serial port. If failed, user authentication performed through local database of ConnectPort LTS again.
authentication server. Port group settings As a convenience feature, port groups can be created to send data to multiple ports. Instead of sending data to individual serial ports, data can be sent to all ports in a group simultaneously through a port in a group. If you select an additional option, you can also see the data from multiple ports in the same group from a terminal connected to the one of serial ports in the group.
Alarms Use the Alarms page to configure device alarms or display current alarms settings. Device alarms are used to send email messages or SNMP traps when certain device events occur. These events include and certain data patterns being detected in the data stream. Alarm notification settings On the Alarms page, the Alarm Notification Settings control the following: Enable alarm notifications: Enables or disables all alarm processing for the Digi Connect device.
Alarm conditions To configure an alarm, click on it. The configuration page for individual alarms has two sections: Alarm Conditions: For specifying the conditions on which the alarm is based, such as serial data pattern matching or data usage. Alarm Destinations: For specifying how the alarm is sent, either as an email message or an SNMP trap, or both, and where the alarm is sent. Alarm conditions The Alarm Conditions part of the page is for specifying the conditions on which the alarm is based.
Enable and Disable Alarms Once alarm conditions are configured, enable and disable individual alarms by selecting or deselecting the Enable checkbox for each alarm. System settings The System Configuration page configures system settings, including device description information, such as the device name, contact, and location, and whether SNMP is enabled or disabled and the SNMP traps that are enabled.
SNMP configuration settings Simple Network Management Protocol (SNMP) is a protocol that can be used to manage and monitor network devices. ConnectPort LTS products can be configured to use SNMP features, or SNMP can be disabled entirely for security reasons. To configure SNMP settings, click the Simple Network Management Protocol link at the middle of the System Configuration page.
Enable Simple Network Management Protocol (SNMP) traps: Enables or disables the generation of SNMP traps. − Trap version: SNMP version for the trap − Trap primary IP: The primary IP address of the system to which traps are sent. In order to enable any of the traps, a non-zero value must be specified. For ConnectPort LTS products that support alarms, this field is required in order for alarms to be sent in the form of SNMP traps. See "Alarms.
Date and Time Settings System Date and Time can be changed on this configuration page. Authentication Settings The authentication settings for system set the authentication method and related settings of Web UI and CLI access. CLI access includes CLI access through serial console, telnet, SSH, Rlogin and Rsh. Remote authentication will use the permissions set to the default "ruser" user.
User settings User settings involve several areas: User authentication: whether authentication is required for users accessing the ConnectPort LTS product, and the information required to access it. Depending on the Digi product, multiple users and their authentication information can be defined. User authentication settings are on the Users settings page. User access settings: the device interfaces that a user can access, such as the command line or web interface.
Password authentication By default, Digi Connect Family devices have password authentication enabled. That means when a login prompt is displayed when accessing the device by opening the web interface or issuing a telnet command. Disable password authentication In ConnectPort LTS, all users should have a password and password authentication cannot be disabled. Change the password for administrative user To increase security, change the password for the administrative user from its default.
Add users Digi Connect Family products allow multiple users to be defined. For those products, the Users Configuration page shows the currently defined users and allows you to add more user definitions. To add a user definition: 1. On the Main menu, click Users. 2. On the Users Configuration page, click New. 3. On the Add New Users page, specify the user name and password to be used for login. The password can be from 4 through 16 characters long and is case-sensitive. Confirm the password, and click Apply.
User permissions settings The User Permissions page is used to define whether and how users can use services and configuration settings for the ConnectPort LTS product. For example, you can disable a user’s access to certain parts of the web interface, or allow them to display settings only but not change them. The list of services and the user permissions available for them vary by ConnectPort LTS product and the features supported in the product.
User permissions and effects Permission Setting Effect None The user does not have permission to execute this setting. Read Self The user can display his/her own settings, but not those of other users. Read The user can read the settings for all users, but does not have permission to modify or write the settings. Read/Write Self The user can read and write his/her own settings, but not those of other users.

PPP configuration PPP (Point-to-point Protocol) provides TCP/IP communication over a modem connected to a serial port on your ConnectPort LTS server. PPP allows you to connect a device to a network using a telephone line and that device has access to the resources of the network as if it were directly connected to the network. Basic PPP settings Under Basic PPP settings, users can set the PPP (Point-to-Point Protocol) options to enable or disable the dynamic IP address pool.
Authentication configuration - User Name: Specifies the username for this connection. The username, along with the password, are specified by the user when connecting to the device. This username must be unique to the device so that no other incoming PPP connection, outgoing PPP connection, or system user uses it. - Password/Confirm Password: Specifies the password for this connection. This is the password that the user specifies when connecting and logging into the device.
Peer configuration: Specifies how the remote IP address that is supplied to the client is assigned. - Automatically Assign Remote IP Address from IP Address Pool: The remote IP address will automatically be assigned with a unique address from the IP address pool (as configured in Basic PPP Settings; see page 93). The assigned address will not conflict with any other PPP connection using the dynamic IP address pool. - Note: This option requires the Dynamic IP Address Pool to be enabled.
Setting up incoming PPP connections To configure the correct settings for incoming PPP connections, you need to configure settings on Application -> PPP first and then configure settings on Configuration -> Serial Ports. Settings on Application -> PPP Basic PPP Settings: To assign an IP address for incoming PPP client automatically, check Enable Dynamic IP Address Pool for Incoming Connections and enter First IP Address and Number of Addresses.
5. In the Peer Configuration section, select an option for assigning the IP address of incoming PPP client. Automatically assign remote IP address from IP address pool: If you select this option, IP address for incoming PPP client will be automatically assigned from the IP address pool set on Basic PPP Settings page Allow remote peer to specify remote IP address: If you select this option, incoming PPP client will specify the IP address used for this PPP connection.
Settings on Serial ports 1. Select a port from Configuration -> Serial ports -> Ports Settings 2. Change the port profile to modem 3. In the Port Profile Settings -> Modem Settings section, Check Incoming Connections. 4. Check Enable PPP connections on this modem. 5. Set configurations on Basic serial settings and Advanced Serial Settings sections according to your environment. 6. Select authentication method of the serial port on Authentication Settings section.
Outgoing PPP Connection Outgoing PPP connections are those connections where the ConnectPort LTS product dials-up to an external modem or ISP. Examples of outgoing PPP connections are typically to automatically connect to an external ISP network when the main Ethernet network goes down. This is to allow the device to continue communication on the network or allow connections from the network when the main Ethernet network is down.
Peer configuration: Specifies how the remote IP address that is supplied to the client is assigned. - Automatically Obtain IP Address from Remote Peer: The IP address will automatically be obtained as supplied by the remote peer. This address, depending on the implementation of the remote peer, will either by dynamic or static. For more information, please contact the service provider of the system being connected to. This is the most commonly used mode and the default.

5 Administration tasks This chapter discusses the administration tasks that need to be performed on ConnectPort LTS products periodically, such as file management, changing the password used for logging onto the device, backing up and restoring device configurations, updating firmware and Boot/POST code, restoring the device configuration to factory defaults, and rebooting the device.
File management The File Management page of the web interface uploads custom files to a ConnectPort LTS product. Custom files allow the flexibility to alter the interface either by adding a different company logo, changing colors, or moving information to different locations. If custom files are note, using this feature is not necessary. Upload files To upload files to a ConnectPort LTS product, enter the file path and name for the file, or click Browse to locate and select the file, and click Upload.
Backup/restore device configurations Once a ConnectPort LTS product is configured, backing up the configuration settings is recommended in case problems occur later, firmware is upgraded, or hardware is added. If multiple devices need to be configured, the backup/restore feature can be used as a convenience, where the device configuration settings are backed up to a file, then the file is loaded onto the other devices.
Backup/restore device configuration from a TFTP or BOOTP Server from the command line From the command-line interface, the “backup” command backs up the device configuration to a TFTP or BOOTP server located on the network or a storage device in the ConnectPort LTS device, or restores the configuration.
Update firmware The firmware for a ConnectPort LTS product can be updated in several ways: In the web interface, by the Administration > Update Firmware page From the command-line interface, via TFTP or BOOTP. The recommended method for firmware upgrade is to download the firmware to a local hard drive. Prerequisites These procedures assume that: A firmware file has already been downloaded from the Digi web site. That TFTP or BOOTP is running. Update firmware from a file from the web interface 1.
Restore a device configuration to factory default settings Restoring a ConnectPort LTS product to its factory default settings clears all current configuration settings. Selecting the Keep network settings option retains the IP address settings. In addition, any files that were loaded into the device through the File Management page such as custom-interface files and applet files are retained.
