Chapter 34 Configuring Local SPAN and RSPAN
Configuring Local SPAN and RSPAN
This example shows how to configure a port as an unconditional IEEE 802.1q trunk:
Router(config)# interface fastethernet 5/12
Router(config-if)# switchport
Router(config-if)# switchport trunk encapsulation dot1q
Router(config-if)# switchport mode trunk
Router(config-if)# switchport nonegotiate
Configuring a Local or RSPAN Destination
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 or RSPAN destination, perform this task:
Note To tag the monitored traffic, you must configure the port to trunk unconditionally before you configure
it as a destination (see the “Configuring a Destination Port as an Unconditional Trunk” section on
page 34-10).
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 , ...
When clearing monitor sessions, note the following syntax information:
• Enter the no monitor session number command with no other parameters to clear
session session_number.
• session_range is first_session_number-last_session_number
Command Purpose
Router(config)# monitor session session_number
destination {single_interface | interface_list |
interface_range | mixed_interface_list} |
{remote vlan rspan_vlan_ID}}
Configures the session number and the destination ports or
RSPAN VLAN.
Router(config)# no monitor session {session_number |
all | local |
range session_range[[,session_range],...] | remote}
Clears the monitor configuration.
