Chapter 22 Configuring SPAN and RSPAN Configuring SPAN and RSPAN Step 5 Command monitor session session_number destination {interface interface-id [, | -] [encapsulation replicate]} Step 6 Step 7 Step 8 end show monitor [session session_number] show running-config copy running-config startup-config Purpose Specify the SPAN session and the destination port (monitoring port). For session_number, specify the session number entered in Step 3. For interface-id, specify the destination port. The destination interface must be a physical port; it cannot be an EtherChannel, and it cannot be a VLAN. (Optional) [, | -] Specify a series or range of interfaces. Enter a space before and after the comma; enter a space before and after the hyphen. (Optional) Enter encapsulation replicate to specify that the destination interface replicates the source interface encapsulation method. If not selected, the default is to send packets in native form (untagged). Return to privileged EXEC mode. Verify the configuration. (Optional) Save the configuration in the configuration file. To monitor all VLANs on the trunk port, use the no monitor session session_number filter global configuration command. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor traffic received on Gigabit Ethernet trunk port 2, and send traffic for only VLANs 1 through 5 and VLAN 9 to destination Gigabit Ethernet port 1. Switch(config)# no monitor session 2 Switch(config)# monitor session 2 source interface gigabitethernet0/2 rx Switch(config)# monitor session 2 filter vlan 1 - 5 , 9 Switch(config)# monitor session 2 destination interface gigabitethernet0/1 Switch(config)# end Configuring RSPAN These sections contain this configuration information: • RSPAN Configuration Guidelines, page 22-15 • Configuring a VLAN as an RSPAN VLAN, page 22-16 • Creating an RSPAN Source Session, page 22-17 • Creating an RSPAN Destination Session, page 22-19 • Creating an RSPAN Destination Session and Configuring Incoming Traffic, page 22-20 • Specifying VLANs to Filter, page 22-22 RSPAN Configuration Guidelines Follow these guidelines when configuring RSPAN: • All the items in the "SPAN Configuration Guidelines" section on page 22-10 apply to RSPAN. • As RSPAN VLANs have special properties, you should reserve a few VLANs across your network for use as RSPAN VLANs; do not assign access ports to these VLANs.
