The Cisco Nexus 5000 Series switch supports two active SPAN sessions. When you configure more than
Note
two SPAN sessions, the first two sessions are active. During startup, the order of active sessions is reversed;
the last two sessions are active. For example, if you configured ten sessions 1 to 10 where 1 and 2 are
active, after a reboot, sessions 9 and 10 will be active. To enable deterministic behavior, explicitly suspend
the sessions 3 to 10 with the monitor session session-number shut command.
