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:
When configuring local SPAN sessions, note the following information:
• local_span_session_number can range from 1 to 66.
• 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 the ID number of a single VLAN.
• vlan_list is single_vlan , single_vlan , single_vlan ...
• vlan_range is first_vlan_ID - last_vlan_ID.
• mixed_vlan_list is, in any order, single_vlan , vlan_range , ...
• To tag the monitored traffic as it leaves a destination port, you must configure the destination port
to trunk unconditionally before you configure it as a destination (see the “Configuring a Destination
Port as an Unconditional Trunk” section on page 52-24).
