Discarding NTP Configuration Changes

After making the configuration changes, you can choose to discard the changes or to commit them. In
either case, the lock is released.
To discard NTP configuration changes, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# ntp abort

Releasing Fabric Session Lock

If you have performed an NTP fabric task and have forgotten to release the lock by either committing or
discarding the changes, an administrator can release the lock from any switch in the fabric. If the
administrator performs this task, your changes to the pending database are discarded and the fabric lock
is released.
Tip The changes are only available in the volatile directory and are subject to being discarded if the switch
is restarted.
To use administrative privileges and release a locked NTP session, use the clear ntp session command.
switch# clear ntp session

can fail if this configuration exists.
Verify that the union of the databases does not exceed the maximum limit of 64.
