Purpose
Updates the configuration and exits ERSPAN source
session configuration mode.
(Optional)
Copies the running configuration to the startup
configuration.
Purpose
Enables privileged EXEC mode. Enter your password if
prompted.
Enters global configuration mode.
Defines an ERSPAN source session using the session ID and
the session type, and places the command in ERSPAN monitor
source session configuration mode.
The span-session-number argument range is from 1 to 1024.
The same session number cannot be used more than once.
The session IDs for source sessions are in the same global ID
space, so each session ID is globally unique for both session
types.
The session ID (configured by the span-session number
argument) and the session type (configured by the
erspan-source keyword) cannot be changed once entered. To
change session ID or session type, use the no version of the
command to remove the session and then re-create the session
through the command with a new session ID or a new session
type.
