Chapter 49 Configuring SPAN Configuring SPAN Send feedback to [email protected] Suspending or Activating a SPAN Session The default is to keep the session state shut. To open a session that duplicates packets from sources to destinations, perform this task: Command switch(config)# no monitor session {all | session-number} shut Purpose Opens the specified SPAN session or all sessions. The following example shows suspending a SPAN session: ... switch(config)# monitor session 3 shut To suspend a SPAN session, perform this task: Command switch(config)# monitor session {all | session-number} shut Purpose Suspends the specified SPAN session or all sessions. Note The Cisco Nexus 5000 Series switch supports two active SPAN sessions. When you configure more than 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. Displaying SPAN Information To display SPAN information, perform this task: Command switch# show monitor [session {all | session-number | range session-range} [brief]] Purpose Displays the SPAN configuration. This example shows how to display SPAN session information: switch# show monitor SESSION STATE 2 up 3 down 4 down REASON The session is up Session suspended No hardware resource DESCRIPTION This example shows how to display SPAN session details: switch# show monitor session 2 session 2 OL-16597-01 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 49-7
