AT-S10 Management Software User’s Guide For information on the hardware installation and connectivity aspects of manageable TurboStack hubs, see the separate TurboStack Ethernet Hubs With Management Installation Manual shipped with each hub.
Overview TCP/IP Networks To manage the hub in TCP/IP, you first configure its IP parameters or at least assign a unique IP address to the hub. You have the option to manage using either SNMP or Omega Remote™ via Telnet. TCP/IP with BootP. The function of the BootP utility within an IP server is to enter an IP address into the hub. Whenever you reset the hub or power it up, it transmits a request packet to the server every three seconds to obtain IP parameters.
Chapter 2 Getting Started This chapter describes the following procedures: ❑ Connecting a terminal to the hub for local management ❑ Initial and optional configurations ❑ Starting an Omega session for initial setup ❑ Using the Omega menus ❑ Connecting to remote TurboStack hubs for remote management Connecting a Terminal Before proceeding, make sure you have installed the hub by following the procedures in the TurboStack Ethernet Hubs with Management Installation Manual and that the hub is functi
Getting Started NOTE These configuration options apply whether you are using Windows or a DOS-based terminal emulator program. To be sure these options are always available, save them as an Omega file (i.e., OMEGA.TRM). If you have previously accessed Allied Telesyn devices with existing terminal settings, use the same ones without recreating a new .TRM file. 4. To activate the emulation program, press Return twice. This ensures configuration of the appropriate baud rate.
AT-S10 Management Software User’s Guide Assigning a Hub Name While specifying an IP or MAC address is enough to communicate with the hub, names are more descriptive and easier to remember. For the same reason, plan to assign names to ports as well (described later in Chapter 3). To name the hub: 1.
Getting Started Entering an IP Address This section applies only if you have TCP/IP. The hub needs an IP address so you can communicate with it via Telnet or SNMP. Other parameters such as subnet mask and gateway addresses are also required if you have them. As discussed in Chapter 1, you may use BootP (if you have it) in your IP server to configure the hub with its IP parameters.
AT-S10 Management Software User’s Guide 4. Continue by entering the letter corresponding to the network parameter you want to configure, as follows: B: Subnet mask. This is required if you have it. C: Gateway address. This is required if you need to send packets from one IP network to another via a router. D through G: SNMP Manager address. You may enter the IP addresses of up to four network management servers that will receive SNMP trap messages. This parameter is optional. H: Download password.
Getting Started Working with the Omega Menus Once you are in session, the hub is locked from other session requests; for example, if using Omega Local, others cannot use Omega Remote on the hub. At initial startup, you are not required to enter a password. You may configure a system password later (described in Chapter 3, “Password” on page 36).
AT-S10 Management Software User’s Guide Configuring Hub Modules in a Chassis If you have a chassis configuration, the main menu lists the installed and active TurboStack modules, enabling you to control any module from a terminal connected to the master (the module in the uppermost slot). The main menu looks like the following screen: Allied Telesyn International AT-TS24TR Stackable Hub: 4.
Getting Started Ending a Session End an Omega session by selecting Quit from the main menu. This returns the management agent to an idle, listening state and breaks the communication link. If connected via a modem, the phone circuit will be “hung up”; if connected via the network, the virtual circuit will be disconnected. NOTE An Omega session automatically quits if there has been no keyboard entry after five minutes. This ensures availability for the next management session.
AT-S10 Management Software User’s Guide Using AT-View® You can purchase an optional network management package called AT-View from Allied Telesyn. This Windows®- and UNIX®-based SNMP software application offers an easy-to-use and inexpensive graphical user interface (GUI). AT-View is ideal for simple and fast diagnostics, configuration, and the monitoring of network devices.
Chapter 3 Management Menus This chapter describes the Omega menus to configure and manage your TurboStack hub. Main Menu When a new session begins, the first screen you see is the main menu, as shown in the following example of a segmented backplane chassis configuration. For illustration purposes, this chapter will show screens of a hub preconfigured with module names. User-assigned hub name Hub model of master module Software version Allied Telesyn International AT-TS12TR Stackable Hub: 4.
Management Menus At the top of the main menu is the product name and software version, and immediately below is the user-assigned hub name, if any (Sunnyvale in this example). The hub modules occupy the first six slots of a seven-slot chassis, and have all been given names. A TurboStack Ethernet switch, the AT-TS90TR, occupies the seventh slot. At the bottom of the screen is a prompt (->), where the cursor is blinking, awaiting input.
AT-S10 Management Software User’s Guide Port Status Menu When you select Port status from the main menu, a menu similar to the following appears: Sunnyvale Module 1—Accounting A Port Status Port AUI port 1: Room 2: Room 3: Room 4: Room 5: 6: 7: 8: 9: 10: 11: 12: 13: MAC Address 1148 1149 1150 1151 00A0D2 0000F4 0000F4 00805F 00805F 000094 00805F 080009 0000F4 0000F4 080020 0080C7 -- 80016E C02789 D0D070 84239F 4810F2 4514A6 E49A0B 984673 D09603 C00520 681B97 68A081 Link Online Online Online Online O
Management Menus Port Configuration Menu If you enter a port number, for example, 1, from the Port status menu, the Port Configuration Menu for Port 1 of a 10Base-T hub appears: Sunnyvale Module 1 — Accounting A Port 1 - Room 1148 Link State: Partitioning State: Polarity: MAC Learning: Online Enabled Normal Enabled Please select an option: > Enable port - with automatic partitioning Disable port > Standard IEEE reconnection algorithm Alternate reconnection algorithm > Link test on Off — no link test > Po
AT-S10 Management Software User’s Guide Reconnection Standard IEEE reconnection algorithm. Entering S for this option specifies that a Partitioned port is automatically changed back to Enabled if this port receives or transmits data without collision for a period of 512 bit times. Alternate reconnection algorithm. Entering A for this option specifies that a Partitioned port is automatically changed back to Enabled only if this port receives data without collision for a period of 512 bit times.
Management Menus Redundant Links Configuration The redundant link feature allows you to configure an alternate path to a critical network resource; this resource can be the backbone or a server running critical applications. You can have up to 6 pairs on a 12-port hub and 12 pairs on a 24-port hub. A redundant pair consists of a primary and a secondary port. After configuration, the primary port is enabled and the secondary port, disabled.
AT-S10 Management Software User’s Guide The software tests the primary port for the following failure conditions: ❑ Loss of link - If the primary port loses its link, the software automatically enables its secondary port. Once the link to the primary port is established again, the software automatically enables the primary port and disables its secondary port.
Management Menus Sunnyvale Module 1—Accounting A Port 13 Redundant Link Assignment Secondary/(primary port) : Null (not currently configured) Receive failure timer (secs) Check & return to primary timer (secs) Resample timer (ms) : 60 : 60 : 200 Please select an option: A: Secondary port Module settings: B: Receive failure timer (secs) C: Check & return to primary timer (secs) D: Resample timer (ms) 4.
AT-S10 Management Software User’s Guide When the secondary port takes over, the port status shows Port 13, the primary, as Disabled/RL; and Port 1, the secondary, as Normal/RL. To configure Check and return to primary timer: The value you enter here has no effect if the primary port’s failure is due to loss of link. When the primary port is autopartitioned or is not receiving data, the secondary port becomes enabled. Within the period you specify here, the software does not check the primary port.
Management Menus As primary port, Port 13 is enabled and actively receives and transmits packets. Port 1 is disabled until Port 13 fails.
AT-S10 Management Software User’s Guide Port Learning Selecting Toggle port learning setting changes a port’s MAC address learning to Disabled if it was previously Enabled, and Enabled if it was previously Disabled. All ports (except the AUI port) are in learning mode by default; they learn and store MAC addresses. If you want to use a port as a “network” port, that is, connected to the backbone, turn off its learning so it does not store uplink addresses.
Management Menus Hub Statistics Menu When you select Hub Statistics from the main menu, the following menu appears: Sunnyvale Please select an option: Hub overview Module overview Individual port overview TOtal frames Good frames Bad frames Crc errors Alignment errors Runt frames LOng frames TRansmit collisions POrt collisions LAte collisions SHort events Jabber lockups PArtitions Data rate mismatches SOurce address changes Zero all statistics counters on the entire hub -> The menu allows you to choose th

Jabber Lockups Transmissions of excessive length that caused the hub module to enter Jabber Lockup mode (available at the hub level only).
Management Menus Statistical information for the entire hub, specific modules, or all ports is displayed in the form of graphs. The graphs dynamically change as frames pass through. 2. Press Return to go to the Hub Statistics menu. To display statistics per module: 1. Select a counter from the Hub Statistics menu.
AT-S10 Management Software User’s Guide Module Statistics Menu This option does not appear on a standalone hub.The default module is Module 1, unless you first select a different module number from the main menu.
Management Menus To display module statistics per counter: 1. Select a counter from the Module Statistics menu.
AT-S10 Management Software User’s Guide Security/Source Address Table Menu Security options are enabled or disabled on a per-module basis only. The default module is Module 1. If you want to configure another module, for example, Module 5, select that module number first from the main menu before using the Security options.
Management Menus The following example is the SAT when you select D: Sunnyvale Module 5-Engineering Source Address Table - Page 1 MAC Address Port MAC Address Port 00AA00 00C07B 080009 080009 080009 080009 080009 080020 00000C 00A0D2 11 2 10 5 13 1 17 3 14 16 0000F4 00AA00 080020 080009 080009 080009 080009 080020 0000F4 0000F4 21 15 8 12 18 4 9 6 7 20 5E3DC2 4D06D3 95D13D 2ADA9D 2B7489 1DFEB5 16BA5A 739089 18E2F3 000285 B1567E 5E3710 74A55B 9BDB2B 681B97 6F5610 984673 715907 E43068 D03D18 Pleas
AT-S10 Management Software User’s Guide Learning Mode The TurboStack hub has two modes of learning: ❑ Learning is on; security is off (the default) ❑ Security is on; learning is off Regardless of the mode you select, SNMP statistics gathering continues.
Management Menus In a secure mode, the system detects intrusions by comparing incoming source addresses to entries on the table. Transmissions from addresses not found in the table are considered intrusions. NOTE The master associates the MAC address table with a specific slot in the chassis. For example, if you lock the MAC address table of the module in Slot 2 and later replace that module with a new one, the new module in Slot 2 inherits the locked MAC address table. 2.
AT-S10 Management Software User’s Guide Administration Menu If you select Administration from the main menu, the following menu appears: Sunnyvale Please select an option: Hub name Module name Omega options Network parameters Terminal configuration Language/langue/idioma/linguaggio/sprache Send updated software to another hub Update software in all hubs Reset hub config to manufacturing defaults Activity monitor EtherMeter Diagnostics Connect to a remote hub -> NOTE The Module name option does not appear
Management Menus Module Name Menu If you choose the Module name option from the Administration menu, a menu similar to the following appears: Sunnyvale Module 1 — Accounting A The module’s current name is: Accounting A Please enter a new name, or Return to retain the existing name: -> The module defaults to Module 1, unless you first selected a different module number from the main menu.
AT-S10 Management Software User’s Guide Omega Local. The default is Enabled for Omega Local. That means you can access the menus from a terminal or PC connected to the hub’s RS-232 port. If you want to disable this option for security reasons, press any key. That means Omega is not accessible via the local interface or the network. This takes effect after quitting the local session. To override, insert the AT-S10 software cassette. ATTENTION If you disable Omega Local, do not quit prematurely.
Management Menus When configuring network parameters for the hub, the software warns you if you enter a wrong address format. You must then press Return to go back to the Network parameters screen. Hub IP Address. Enter A to display the Hub IP address screen as shown: Sunnyvale The current Hub IP Address is: Null (not currently configured) Please enter a new value, or Return to retain the existing one. Enter a value in the form of a.b.c.d, where a, b, c, and d are each in the range 0-255.
AT-S10 Management Software User’s Guide SNMP Manager Address . Enter D, E, F, or G to display the SNMP Manager address screen as shown: Sunnyvale The current SNMP Manager Address is: Null (not currently configured) Please enter a new value, or Return to retain the existing one. Enter a value in the form of a.b.c.d., where a, b, c, and d are each in the range 0-255. For example: 128.9.3.1 -> Then enter the IP address of the SNMP management station that is to receive SNMP trap messages.
Management Menus “Trap” Community String. The default value is public. To change it, enter J to display the screen as shown: Sunnyvale The current ‘Trap’ Community String is: public Please enter a new string, or Return to retain the existing one: -> Then enter up to ten characters for the SNMP Trap community string. Download Password. The default password, ATS10 (in uppercase), displays as a series of asterisks for protection.
AT-S10 Management Software User’s Guide Contact String. This parameter is optional. Enter M to display the following screen: Sunnyvale ‘Contact’ is a string that identifies the person primarily responsible for this device (someone to contact in case of problems), e.g., “Joe Smith”.
Management Menus Table 2: Required Terminal Control Characters Control Code What It Does Carriage Return hex 0D Moves the cursor to column 1 of the current file Line Feed hex 0A Moves the cursor down one line; if at the bottom of the screen, scrolls the screen up one line Backspace hex 08 Moves the cursor back one character space Omega can also take advantage of selected special control (escape) sequences that the terminal may use for screen control. Table 3 lists these special sequences.
AT-S10 Management Software User’s Guide Data Rate. Omega supports the following data rates: ❑ 19200 bps ❑ 9600 bps ❑ 4800 bps ❑ 2400 bps ❑ 1200 bps ❑ 600 bps ❑ 300 bps ❑ 150 bps ❑ 75 bps ❑ Automatic baud rate detection (the default) It is best to keep the default configuration, automatic baud rate detection, by pressing Return twice. The two Returns determine the terminal’s actual data rate.
Management Menus The main menu in Spanish then appears as follows: Centro Extensible AT-TS12TR de Allied Telesyn International: 4.0 Sunnyvale Por favor seleccione una opcion: Estado de puerto Centro - estadistica Modulo - estadistica Generalidades de puerto SEcurity/Source Address Table Administracion SAlida -> The management agent “remembers” and retains the selected language through a power failure.
AT-S10 Management Software User’s Guide After this message is broadcast, the management agent switches to Activity Monitor mode to enable you to monitor download activity. The screen displays messages similar to the following example: Activity Monitor (hit Return to resume the previous menu) Download request received from Third Floor Hub Sending...
Management Menus If an unrecognized type of TFTP request is received, the following message appears: Sunnyvale TFTP request received from node >: Implied request ignored The symbol > denotes the IP address of the requesting node in dotted decimal notation. EtherMeter The EtherMeter option on the Administration menu modifies the function of the port indicators on the current hub module’s front panel. The indicators ordinarily display network activity on an indicator-per-port basis.
AT-S10 Management Software User’s Guide The Diagnostics screen is the only place on the user interface where the MAC address is displayed. The results for each test will either indicate Good or Failed. Diagnostic tests may be run on any module within a department concentrator. If the currently selected module has a failure and can no longer communicate across the backplane bus, the message “Module does not respond” appears.
Chapter 4 Fault Tolerance This chapter describes the behavior of master and slave hubs in terms of module failure in a chassis configuration. It also provides procedures on how to swap failed modules in the chassis. CAUTION NEVER power off modules while they are in the chassis, because modules are not isolated from the backplane. When power cycling, ALWAYS slide the module out first, disconnect the power cord, reconnect the power cord, and then slide the module back in.
Fault Tolerance Department Concentrator Reconfiguration Each module in a department concentrator of multiple hubs knows its own slot position within the chassis, and which other slot positions are occupied. From this information, each module determines whether it should act in the capacity of a master, backup, or slave. This process is called role determination. Role determination occurs as soon as you power up or reset the department concentrator.
AT-S10 Management Software User’s Guide If you removed the failed master, role determination causes the entire department concentrator to reconfigure itself with new master and backup. A new module then becomes the backup to the new master (the previous backup). A failure of the backup cannot be corrected without removing the module itself; i.e., no other module can act as a backup for the backup. Configuration Data The master records all management agent configuration information in nonvolatile memory.
Fault Tolerance Voting During the voting process, the master polls each installed module and examines the stored configuration data. The master declares the configuration data that is stored on the greatest number of modules as the correct data, that is, the majority rules. For example, if data set A exists on modules 1, 3, and 4, and data set B exists on module 5, the management agent accepts data set A to be correct and adopts this set of configuration data for subsequent use.
Chapter 5 Software Upgrades This chapter describes the procedures to upgrade hub software. The Omega firmware, AT-S10, is pre-loaded in manageable TurboStack modules at the factory and is ready to use. There are various ways to install or upgrade your firmware: ❑ Install the AT-S10 firmware cassette in the firmware port. ❑ Use TFTP. ❑ Upgrade the software in one TurboStack hub using the firmware cassette, and then download to other TurboStack hubs on the network.
Software Upgrades Using the Firmware Cassette You can order an AT-S10 cassette (see Figure 3) separately for backup. Thumbscrews Figure 3: AT-S10 Firmware Cassette You can use this compact cassette to override the login options for password protection and locking out Local Omega. The firmware cassette includes network management agent software for any manageable TurboStack module: ❑ SNMP Agent supporting MIB-II, and Repeater MIB (RFC 1516), and Allied Telesyn proprietary MIB (ATHUB.
AT-S10 Management Software User’s Guide To reinstall or update the management agent using the cassette: 1. Remove the master from the chassis if this is a department concentrator configuration; otherwise, skip to Step 2. NOTE When removing any department concentrator module, always disengage the module from the chassis backplane before unplugging the power cord; i.e., use the hot swapping method. Refer to your chassis manual for more information. The module is now a standalone hub. 2.
Software Upgrades NOTE You may leave the cassette installed. If you do, however, the module cannot receive downloads over the network. This is because the software network download does not overwrite a cassette. Password protection is also disabled when the cassette is installed. 8. Plug the power cord back into the hub. For a standalone hub, the software installation is complete. 9. Return the hub into the master uppermost slot in the chassis, if you have a department concentrator configuration.
AT-S10 Management Software User’s Guide To update a specific hub: 1. Select Send updated software to another hub from the Administration menu. The following screen appears: Sunnyvale Please specify the Hub to be downloaded: The Hub to be downloaded may be identified by name (‘hub name’), by IP address (128.2.3.4), or by Ethernet address (0000F4 123456). -> 2. Enter either the hub’s IP address, MAC address, or name. 3. The activity monitor appears, displaying messages about the download process.
Software Upgrades TFTP If you have a TCP/IP network, you can use TFTP to send or get the latest software. The source can be a TurboStack hub with the latest software or Allied Telesyn’s Bulletin Board Services or web site. Check these services for the latest software (the image file) and the steps to download them. Following are examples of TFTP commands.
