Step 18
Shutting Down or Activating an ERSPAN Session
You can shut down ERSPAN sessions to discontinue the copying of packets from sources to destinations.
Because only a specific number of ERSPAN sessions can be running simultaneously, you can shut down a
session to free hardware resources to enable another session. By default, ERSPAN sessions are created in the
shut state.
You can enable ERSPAN sessions to activate the copying of packets from sources to destinations. To enable
an ERSPAN session that is already enabled but operationally down, you must first shut it down and then
enable it. You can shut down and enable the ERSPAN session states with either a global or monitor
configuration mode command.
