Chapter 23 Configuring SPAN and RSPAN Configuring SPAN and RSPAN Creating an RSPAN Destination Session You configure the RSPAN destination session on a different switch; that is, not the switch on which the source session was configured. Beginning in privileged EXEC mode, follow these steps to define the RSPAN VLAN on that switch, to create an RSPAN destination session, and to specify the source RSPAN VLAN and the destination port: Step 1 Step 2 Command configure terminal vlan vlan-id Step 3 Step 4 Step 5 remote-span exit no monitor session {session_number | all | local | remote} Step 6 monitor session session_number source remote vlan vlan-id Step 7 monitor session session_number destination interface interface-id Step 8 end Step 9 show monitor [session session_number] show running-config Step 10 copy running-config startup-config Purpose Enter global configuration mode. Enter the VLAN ID of the RSPAN VLAN created from the source switch, and enter VLAN configuration mode. If both switches are participating in VTP and the RSPAN VLAN ID is from 2 to 1005, Steps 2 through 4 are not required because the RSPAN VLAN ID is propagated through the VTP network. Identify the VLAN as the RSPAN VLAN. Return to global configuration mode. Remove any existing RSPAN configuration for the session. For session_number, the range is 1 to 66. Specify all to remove all RSPAN sessions, local to remove all local sessions, or remote to remove all remote SPAN sessions. Specify the RSPAN session and the source RSPAN VLAN. For session_number, the range is 1 to 66. For vlan-id, specify the source RSPAN VLAN to monitor. Specify the RSPAN session and the destination interface. For session_number, enter the number defined in Step 6. In an RSPAN destination session, you must use the same session number for the source RSPAN VLAN and the destination port. For interface-id, specify the destination interface. The destination interface must be a physical interface. Though visible in the command-line help string, encapsulation replicate is not supported for RSPAN. The original VLAN ID is overwritten by the RSPAN VLAN ID, and all packets appear on the destination port as untagged. Return to privileged EXEC mode. Verify the configuration. (Optional) Save the configuration in the configuration file. To delete a SPAN session, use the no monitor session session_number global configuration command. To remove a destination port from the SPAN session, use the no monitor session session_number destination interface interface-id global configuration command. To remove the RSPAN VLAN from the session, use the no monitor session session_number source remote vlan vlan-id. OL-8603-04 Catalyst 2960 Switch Software Configuration Guide 23-19
