SPAN Configuration Guidelines
• To remove a source or destination port or VLAN from the SPAN session, use the
no monitor session
session_number source {
interface interface-id
|
vlan vlan-id
} global configuration command or the
no
monitor session session_number destination interface interface-id global configuration command.
For destination interfaces, the encapsulation options are ignored with the no form of the command.

configuration command.

use as RSPAN VLANs; do not assign access ports to these VLANs.
