Configuring ERSPAN
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.
