Configuring SPAN and RSPAN Chapter 23 Configuring SPAN and RSPAN This example shows how to configure VLAN 901 as the source remote VLAN and port 1 as the destination interface: Switch(config)# monitor session 1 source remote vlan 901 Switch(config)# monitor session 1 destination interface gigabitethernet0/1 Switch(config)# end Creating an RSPAN Destination Session and Configuring Incoming Traffic Beginning in privileged EXEC mode, follow these steps to create an RSPAN destination session, to specify the source RSPAN VLAN and the destination port, and to enable incoming traffic on the destination port for a network security device (such as a Cisco IDS Sensor Appliance). For details about the keywords not related to incoming traffic, see the "Creating an RSPAN Destination Session" section on page 23-19. This procedure assumes that the RSPAN VLAN has already been configured. Step 1 Step 2 Step 3 Step 4 Command Purpose configure terminal Enter global configuration mode. no monitor session {session_number | all | Remove any existing SPAN configuration for the session. local | remote} monitor session session_number source remote vlan vlan-id 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. monitor session session_number destination {interface interface-id [, | -] [ingress {dot1q vlan vlan-id | untagged vlan vlan-id | vlan vlan-id}]} Specify the SPAN session, the destination port, the packet encapsulation, and the incoming VLAN and encapsulation. For session_number, enter the number defined in Step 4. 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. (Optional) [, | -] Specify a series or range of interfaces. Enter a space before and after the comma; enter a space before and after the hyphen. Enter ingress with additional keywords to enable forwarding of incoming traffic on the destination port and to specify the encapsulation type: • dot1q vlan vlan-id-Forward incoming packets with IEEE 802.1Q encapsulation with the specified VLAN as the default VLAN. • untagged vlan vlan-id or vlan vlan-id-Forward incoming packets with untagged encapsulation type with the specified VLAN as the default VLAN. 23-20 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
