Chapter 29 Configuring SPAN and RSPAN
Configuring SPAN and RSPAN
To delete a SPAN session, use the no monitor session session_number global configuration command.
To remove a source port or VLAN from the SPAN session, use the no monitor session session_number
source {interface interface-id | vlan vlan-id} global configuration command. To remove the RSPAN
VLAN from the session, use the no monitor session session_number destination remote vlan vlan-id.
source {interface interface-id | vlan vlan-id} global configuration command. To remove the RSPAN
VLAN from the session, use the no monitor session session_number destination remote vlan vlan-id.
This example shows how to remove any existing RSPAN configuration for session 1, configure RSPAN
session 1 to monitor multiple source interfaces, and configure the destination as RSPAN VLAN 901.
