Configuring Local SPAN and RSPAN
Configuring RSPAN VLANs
To configure a VLAN as an RSPAN VLAN, perform this task:
Configuring Local or RSPAN Sources
Note To configure an RSPAN source session, configure a source with an RSPAN VLAN as the destination. To
configure an RSPAN destination session, configure an RSPAN VLAN as the source and a port as the
destination.
To configure a local SPAN or RSPAN source, perform this task:
When configuring monitor sessions, note the following syntax information:
• single_interface is interface type slot/port; type is ethernet, fastethernet, gigabitethernet, or
tengigabitethernet.
• interface_list is single_interface , single_interface , single_interface ...
Note In lists, you must enter a space before and after the comma. In ranges, you must enter a space
before and after the dash.
• interface_range is interface type slot/first_port - last_port
• mixed_interface_list is, in any order, single_interface , interface_range , ...
• single_vlan is a the ID number of a single VLAN.
• vlan_list is single_vlan , single_vlan , single_vlan ...
Command Purpose
Step 1
Router(config)# vlan
vlan_ID{[-vlan_ID]|[,vlan_ID])
Creates or modifies an Ethernet VLAN, a range of

Step 2

Clears the RSPAN VLAN configuration.
Step 3
Router(config-vlan)# end
Updates the VLAN database and returns to privileged
EXEC mode.
Command Purpose
Router(config)# monitor session session_number source
{{single_interface | interface_list | interface_range
| mixed_interface_list | single_vlan | vlan_list |
vlan_range | mixed_vlan_list} [rx | tx | both]} |
{remote vlan rspan_vlan_ID}}
Configures the session number, the source ports, VLANs, or
RSPAN VLAN, and the traffic direction to be monitored.
Router(config)# no monitor session {session_number |
all | local |
range session_range[[,session_range],...] | remote}
