1 Invisible Body Tag Setting the Initial Switch Configuration The Departmental Switch Model DS-16B2 requires a connection to your IP network. This chapter provides information on how to set up initial configuration tasks for a switch. ◆ ◆ ◆ ◆ ◆ ◆ Logging In to a Switch.......................................................................1-2 Enabling Licensed Features ..............................................................1-3 Displaying the Installed Feature Licenses .............................
Setting the Initial Switch Configuration 1 Logging In to a Switch The switch must be connected to an IP network through the RJ-45 port to enable a connection through Telnet. Refer to the Departmental Switch DS-16B2 Hardware Reference Manual for more information about connecting the switch to your IP network. To log into a Departmental Switch DS-16B2 switch: 1. Open a Telnet connection to the switch. The login prompt displays if the Telnet connection successfully found the switch in the network.
Setting the Initial Switch Configuration Enabling Licensed Features Licensed features such as Departmental Switch DS-16B2 Fabric Watch, Departmental Switch DS-16B2 Extended Fabrics, and Departmental Switch DS-16B2 ISL Trunking are already loaded onto the switch firmware, but you must enable them with a license key. Once you purchase these features, you receive a key to unlock the feature. To enable a licensed feature: 1. Log in to the switch as the admin user. 2.
Setting the Initial Switch Configuration 1 Displaying the Installed Feature Licenses To display what features have been enabled on a switch: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: licenseShow This command displays the license keys that have been entered for the switch and the features enabled by those licenses.
Setting the Initial Switch Configuration Configuring the IP Address The Departmental Switch DS-16B2 switch is shipped with a default IP address of 10.77.77.77. To change the default IP Address and configure the Fibre Channel IP address of the switch: 1. Login to the switch as the admin user. 2. At the command line, enter the following command: ipAddrSet 3. An interactive session opens and prompts you for configuration values. a.
Setting the Initial Switch Configuration 1 Displaying the Fabric-Wide Device Count To verify that you have fabric-wide connectivity when you install a new switch, display the fabric-wide device count from the newly installed switch. To display the fabric-wide device count from a switch: 1. Login to the switch as the admin user. 2. At the command line, enter the following command: nsAllShow This command displays all the connected devices in the fabric.
2 Invisible Body Tag Basic Switch Configuration Procedures This chapter provides the following information on basic configuration tasks for Departmental Switch Model DS-16B2 switch. ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ Setting the Telnet Timeout Value .....................................................2-2 Displaying the Firmware Version ....................................................2-2 Setting the Switch Date and Time....................................................
Basic Switch Configuration Procedures 2 Setting the Telnet Timeout Value To set a new Telnet timeout value: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: timeout x where x is the number of minutes before the Telnet connection times out. If you specify 0, then the connection never times out. Timeout is disabled by default. Displaying the Firmware Version To display the firmware version: 1. Log in to the switch as the admin user. 2.
Basic Switch Configuration Procedures Setting the Switch Date and Time All switches maintain current date and time in nonvolatile memory. Date and time are used for logging events. Switch operation does not depend on the date and time; a switch with an incorrect date and time value still functions properly. To set the date and time of a switch: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: date "MMDDhhmmYY" where: MM is the month, valid values are 01-12.
Basic Switch Configuration Procedures 2 Displaying the System Configuration Settings To display the system configuration settings: 1. Login to the switch as the admin user. 2. At the command line, enter the following command: configShow The system configuration settings displays. For more information on the system configuration settings, refer to the Departmental Switch Model DS-16B2 Fabric OS Reference Manual. Backing Up the System Configuration Settings Currently, only the RSHD.EXE and CAT.
Basic Switch Configuration Procedures Restoring the System Configuration Settings To restore the system configuration settings from a backup: 1. Verify that the RSHD service (on UNIX hosts only) or the FTP service (on a UNIX or Windows host) is running on the host workstation. 2. Log in to the switch as the admin user. 3. Shut down the switch by entering the following command: switchDisable 4. At the command line, enter the following command: configDownload hostIPaddr, user, path_filename, password 5.
Basic Switch Configuration Procedures 2 Upgrading or Restoring the Switch Firmware To upgrade or restore the switch firmware: 1. Verify that the RSHD service/utilities or the FTP service is running on the host workstation. 2. Log in to the switch as the admin user. 3. At the command line, enter the following command: firmwareDownload 4. Press ENTER. The system prompts you to enter the Host IP address, User Name, Filename, and password. The password operand is only required if you are using FTP. 5.
Basic Switch Configuration Procedures Enabling a Switch To enable a switch: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: switchEnable All Fibre Channel ports that passed the POST test are enabled. If the switch was part of a fabric, the switch rejoins the fabric. Disabling a Port To disable a port: 1. Log in to the switch as the admin user. 2.
Basic Switch Configuration Procedures 2 Changing a Switch Name To change the name of a switch: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: switchName "new_name" where new_name is the new name for the switch. Switch names can be up to 19 characters long, must begin with a letter, and can contain letters, numbers, or the underscore character.
Basic Switch Configuration Procedures Setting the Switch Status Policy There are seven parameters that determine the status of a switch: ◆ Number of faulty ports ◆ Missing GBICs (i.e., Small Form Factor Pluggable transceivers) ◆ Power supply status ◆ Temperature in enclosure ◆ Fan speed ◆ Port status ◆ sgroup ISL status Only one parameter needs to pass the MARGINAL or DOWN threshold to change the overall status of the switch.
Basic Switch Configuration Procedures 2 Enabling the Track Changes Feature To enable the track changes feature: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: trackChangesSet 1 A prompt is displayed verifying that the track changes feature is on. The output from the track changes feature is dumped to the error log for the switch. Use the errdump command or errshow command to view the error log.
Basic Switch Configuration Procedures Configuring a Static Route Between Two Ports To configure a static route between two ports: 1. Log in to the switch as the admin user. 2. At the command line, enter the following command: uRouteConfig port, domain, outputport where port is the port to be statically routed; can be either an F_Port or an E_Port. domain is the domain ID of the specified target switch, and outputport is the output port where traffic is to be forwarded.
Basic Switch Configuration Procedures 2 Reading Hexadecimal Port Diagrams Many of the commands return port diagrams in hexadecimal format. Example switch:admin> bcastShow Group Member Ports Member ISL Ports Static ISL Ports -----------------------------------------------------------256 0x00012083 0x00002080 0x00000000 To read the hexadecimal port diagrams, they must be converted into binary notation. Each hexadecimal value represents four binary values.
Basic Switch Configuration Procedures Once the hexadecimal is converted into a binary bit map, each bit represents a port, where a value of 1 means yes and a value of 0 means no. The bit map is read from right to left, that is, the least significant bit represents port 0.
