Configuring an ERSPAN Source Session
The ERSPAN source session defines the session configuration parameters and the ports or VLANs to be
monitored.
Command or Action

Step 3
Switch(config)#
monitor session
span-session-number
type erspan-source
Defines an ERSPAN source session using the session ID and the
session type, and enters ERSPAN monitor source session
configuration mode.
•
Session IDs for source sessions or destination sessions are in the
same global ID space, so each session ID is globally unique for
both session types.
•
The
span-session-number
and the session type (configured by
the
erspan-source
keyword) cannot be changed once
configured. Use the
no
form of this command to remove the
session and then re-create the session with a new session ID or
a new session type.
