Locking a Running Configuration in NETCONF

For a NETCONF client to change a configuration in Cisco IOS XR, it is recommended for the client to acquire a lock to prevent simultaneous update from another NETCONF client or CLI session.

To acquire a configuration lock, the NETCONF client sends a RPC request to lock the running datastore. In Cisco IOS XR 6.1.x and previous releases, the RPC request candidate data-store was the target for acquiring the lock. But from release 6.2.x and later, the request running data-store must be sent to successfully lock the configuration.

Example: NETCONF request with running data-store as target to successfully lock a configuration:

<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
       <lock>
         <target>
           <running/>                                                                                   
         </target>
       </lock>
</rpc> 

Interface Name Modified

Prior to IOS XR Release 6.2.1, 1 Gigabit Ethernet and 10 Gigabit Ethernet interfaces were both named as TenGigE. Also, 40 Gigabit Ethernet and 100 Gigabit Ethernet interfaces were both named as HundredGigE. From Release 6.2.1 onwards, the names have been modified to:

Note	After upgrading to Release 6.2.3, the old configurations applied to 1G and 40G interfaces will not be available. Therefore you must reconfigure the 1G and 40G interfaces using the new names.
