Chapter Setting the Initial Configuration 1 This chapter provides information on initial configuration tasks for a switch. Logging into a Switch To log into a switch: 1. Open a telnet connection to the switch. The login prompt is displayed if the telnet connection successfully found the switch in the network. Note: 2. The switch must be connected to your IP network through the RS-232 port to enable connection through telnet.
1 Setting the Initial Configuration Enabling Licensed Features Licensed features are already loaded onto the switch firmware, but must be enabled with a license key. Once you have purchased these features you are provided with a key to unlock the feature. To enable a licensed feature: 1. Login to the switch as the admin user. 2. At the command line enter the following command: licenseAdd “aaaBbbCcc” where aaaBbbCcc is the license key for a particular feature.
Setting the Initial Configuration 1 Configuring the IP and Fibre Channel Address The 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 An interactive session is opened and you are prompted for configuration values.

Chapter Basic Configuration Procedures 2 This chapter provides information on basic configuration tasks for a switch. Setting the Telnet Timeout Value To set a new telnet timeout value: 1. Login 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 telnet connection never times out. Timeout is disabled by default.
2 Basic Configuration Procedures Setting the Switch Date and Time All switches maintain current date and time in non-volatile 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. Login 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 Configuration Procedures 2 Backing Up the System Configuration Settings The two supplied utilities RSHD.EXE and CAT.EXE, currently do not support uploads for Windows, only downloads. Therefore, FTP must be used on Windows workstations to backup the system configuration, and the FTP server must be running before an upload can occur. To upload a backup copy of the configuration settings to a host computer: 1.
2 Basic Configuration Procedures Upgrading or Restoring the Switch Firmware To upgrade or restore the switch firmware: 1. Verify that the RSHD service (on a UNIX machine) or the FTP service (on a Windows machine) is running on the host workstation. 2. Login to the switch as the admin user. 3.
Basic Configuration Procedures 2 Disabling a Port To disable a port: 1. Login to the switch as the admin user. 2. At the command line enter the following command: portDisable portnumber where portnumber is the number of the port you want to disable. If the port is connected to another switch the fabric may reconfigure. If the port is connected to one or more devices, these devices are no longer available to the fabric. Enabling a Port To enable a port: 1. Login to the switch as the admin user. 2.
2 Basic Configuration Procedures • • Port status sgroup ISL status Each parameter can be adjusted so that a specific threshold must be reached before that parameter changes the overall status of a switch to MARGINAL or DOWN. only one parameter needs to pass the MARGINAL or DOWN threshold to change the overall status of the switch. Viewing the Policy Threshold Values To view the switch status policy threshold values: 1. Login to the switch as the admin user. 2.
Basic Configuration Procedures • • • • 4. 2 Enter the number of port down warnings required to change the switch status to DOWN and press the Enter key. Enter the number of port down warnings required to change the switch status to MARGINAL and press the Enter key. Enter the number of ISLstatus down warnings required to change the switch status to DOWN and press the Enter key. Enter the number of ISLstatus down warnings required to change the switch status to MARGINAL and press the Enter key.
2 Basic Configuration Procedures Displaying whether Track Changes is Enabled To display the status of the track changes feature: 1. Login to the switch as the admin user. 2. At the command line enter the following command: trackChangesShow The status of the track changes feature is displayed as either on or off. This also displays whether the track changes feature is configured to send SNMP traps.
Basic Configuration Procedures 2 Forcing In-order Delivery of Frames To force in-order delivery of frames during fabric topology changes: 1. Login to the switch as the admin user. 2. At the command line enter the following command: iodset Note: This command can cause a delay in the establishment of a new path when a topology change occurs, and should be used with care. Disabling In-order Delivery of Frames To disable In-Order Delivery of frames during fabric topology changes: 1.
2 Basic Configuration Procedures Configuring Compatibility with the F16 Switch In order for HP Brocade 2400 and 2800 switches to be part of a fabric containing an F16 switch switch, the VC Encoded Address Mode parameter must be enabled. The VC Encoded Address Mode parameter specifically enables compatibility between newer switches and the F16 switches. The VC Encoded Address Mode parameter must be enabled on each HP Brocade 2400 and 2800 switch in the fabric.
Basic Configuration Procedures 2 Reading Hexadecimal Port Diagrams Many of the commands return port diagrams in Hexadecimal format. For 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.
