SUMMARY STEPS

configure terminal

vlan vlan-id

remote-span

end

DETAILED STEPS

PurposeCommand or Action

Enters the global configuration mode.configure terminal

Example:

Switch# configure terminal

Step 1

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.

vlan vlan-id

Example:

Switch(config)# vlan 100

Step 2

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.remote-span

Example:

Switch(config-vlan)# remote-span

Step 3

Returns to privileged EXEC mode.end

Example:

Switch(config-vlan)# end

Step 4

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-span VLAN configuration command.
