Configuring SPAN and RSPAN

Configuring a VLAN as an RSPAN VLAN

SUMMARY STEPS

1.configure terminal

2.vlan vlan-id

3.remote-span

4.end

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure terminal	Enters the global configuration mode.
	Example:
	Switch# configure terminal

Step 2	vlan vlan-id
	Example:
	Switch(config)# vlan 100
Step 3	remote-span
	Example:
	Switch(config-vlan)# remote-span
Step 4	end
	Example:
	Switch(config-vlan)# end

Enters a VLAN ID to create a VLAN, or enters the VLAN ID of an existing VLAN, and enter VLAN configuration mode. The range is 2 to 1001 and 1006 to 4094.

The RSPAN VLAN cannot be VLAN 1 (the default VLAN) or VLAN IDs 1002 through 1005 (reserved for Token Ring and FDDI VLANs).

Configures the VLAN as an RSPAN VLAN.

Returns to privileged EXEC mode.

What to Do Next

You must create the RSPAN VLAN in all switches that will participate in RSPAN. If the RSPAN VLAN-ID is in the normal range (lower than 1005) and VTP is enabled in the network, you can create the RSPAN VLAN in one switch, and VTP propagates it to the other switches in the VTP domain. For extended-range VLANs (greater than 1005), you must configure RSPAN VLAN on both source and destination switches and any intermediate switches.

Use VTP pruning to get an efficient flow of RSPAN traffic, or manually delete the RSPAN VLAN from all trunks that do not need to carry the RSPAN traffic.

To remove the remote SPAN characteristic from a VLAN and convert it back to a normal VLAN, use the no remote-spanVLAN configuration command.
