Shutting Down Or Resuming A Span Session - Cisco Nexus 7000 Series Configuration Manual

Shutting Down or Resuming a SPAN Session

Shutting Down or Resuming a SPAN Session
You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations. You
can shut down one session in order to free hardware resources to enable another session. By default, SPAN
sessions are created in the shut state.
You can resume (enable) SPAN sessions to resume the copying of packets from sources to destinations. In
order to enable a SPAN session that is already enabled but operationally down, you must first shut it down
and then enable it.
You can configure the shut and enabled SPAN session states with either a global or monitor configuration
mode command.
