Configuring an RSPAN Session
A RSPAN session is similar to a SPAN session, with the destination interface being an RSPAN tunnel.
To configure an RSPAN session in the source switch for the scenario in
Command
Step 1
switchS# config t
Step 2
switchS(config)# span session 2
switchS(config-span)#
Step 3
switchS(config-span)# destination interface
fc-tunnel 100
Step 4
switchS(config-span)# source interface fc1/1

Configuration in All Intermediate Switches

This section identifies the tasks that must be performed in all intermediate switches in the end-to-end
path of the RSPAN tunnel:

Purpose
Enters configuration mode.
Configures the specified interface.
Configures the ST port mode for interface fc2/1.
Configures the ST port speed to 2000 Mbps.
Associates and binds the ST port with the RSPAN
tunnel (100).
Enables traffic flow through this interface.
Purpose
Enters configuration mode.
Configures the specified SPAN session (2).
If the session does not exist, it is created. The
session ID ranges from 1 to 16.
Configures the specified RSPAN tunnel
(100) in a session.
Configures the source interface (fc1/1) for
this session and spans the traffic from
interface fc1/1 to RSPAN tunnel 100.
