Configuring Local Span - Cisco 7604 Configuration Manual

Chapter 52 Configuring Local SPAN, RSPAN, and ERSPAN

Configuring Local SPAN

Local SPAN does not use separate source and destination sessions. To configure a local SPAN session,
configure local SPAN sources and destinations with the same session number. To configure a local SPAN
session, perform this task:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# monitor session
local_span_session_number source {{ single_interface |
interface_list | interface_range | mixed_interface_list
| single_vlan | vlan_list | vlan_range |
mixed_vlan_list } [rx | tx | both]}}
Step 3
Router(config)# monitor session
local_span_session_number destination { single_interface
| interface_list | interface_range |
mixed_interface_list }
Router(config)# no monitor session { session_number | all
| local | range session_range [[, session_range ],...]}
