CFS Support for Applications Chapter 21 Using Cisco Fabric Services Send feedback to [email protected] 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 Application: port-security Scope : Logical VSAN Domain IP Address User Name User Type 1 238 10.76.100.167 admin CLI/SNMP v3 2 211 10.76.100.167 admin CLI/SNMP v3 Total number of entries = 2 The show cfs lock name command displays the lock details for the specified application: switch# show cfs lock name 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 Committing Changes A commit operation saves the pending database for all application peers and releases the lock for all switches. 21-8 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide OL-16597-01
