Syntax Description This command has no arguments or keywords.
Defaults No RSPAN VLANs are defined.
Command Modes VLAN configuration (config-VLAN)
Command History
Usage Guidelines You can configure RSPAN VLANs only in config-VLAN mode (entered by using the vlan global
configuration command), not the VLAN configuration mode entered by using the vlan database
privileged EXEC command.
If VLAN Trunking Protocol (VTP) is enabled, the RSPAN feature is propagated by VTP for VLAN-IDs
that are lower than 1005. If the RSPAN VLAN ID is in the extended range, you must manually configure
intermediate switches (those in the RSPAN VLAN between the source switch and the destination
switch).
Before you configure the RSPAN remote-span command, use the vlan (global configuration) command
to create the VLAN.
The RSPAN VLAN has these characteristics:
• No MAC address learning occurs on it.
• RSPAN VLAN traffic flows only on trunk ports.
• Spanning Tree Protocol (STP) can run in the RSPAN VLAN, but it does not run on RSPAN
destination ports.
When an existing VLAN is configured as an RSPAN VLAN, the VLAN is first deleted and then recreated
as an RSPAN VLAN. Any access ports are made inactive until the RSPAN feature is disabled.
