Using Cisco Fabric Services Locking the Network Note The show cfs application command only displays applications registered with CFS. Conditional services that use CFS do not appear in the output unless these services are running. switch# show cfs application Application Enabled Scope ntp No Physical-all fscm Yes Physical-fc rscn No Logical fctimer No Physical-fc syslogd No Physical-all callhome No Physical-all fcdomain Yes Logical device-alias Yes Physical-fc Total number of entries = 8 The show cfs application name command displays the details for a particular application. It displays the enabled/disabled state, timeout as registered with CFS, merge capability (if it has registered with CFS for merge support), and lastly the distribution scope. switch# show cfs application name fscm Enabled Timeout Merge Capable Scope : Yes : 100s : No : Physical-fc Locking the Network When you configure (first time configuration) a feature (or application) that uses the CFS infrastructure, that feature starts a CFS session and locks the network. When a network is locked, the switch software allows configuration changes to this feature only from the switch holding the lock. If you make configuration changes to the feature from another switch, the switch issues a message to inform the user about the locked status. The configuration changes are held in a pending database by that application. If you start a CFS session that requires a network lock but forget to end the session, an administrator can clear the session. If you lock a network at any time, your user name is remembered across restarts and switchovers. If another user (on the same machine) tries to perform configuration tasks, that user's attempts are rejected. Verifying CFS Lock Status The show cfs lock command displays all the locks that are currently acquired by any application. For each application the command displays the application name and scope of the lock taken. If the application lock is taken in the physical scope, then this command displays the switch WWN, IP address, user name, and user type of the lock holder. If the application is taken in the logical scope, then this command displays the VSAN in which the lock is taken, the domain, IP address, user name, and user type of the lock holder. switch# show cfs lock Application: ntp Scope : Physical Switch WWN IP Address User Name User Type 20:00:00:05:30:00:6b:9e 10.76.100.167 admin CLI/SNMP v3 Total number of entries = 1 OL-16597-01 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 305
