• Verify that there are no alarms on the interfaces. Use the show
network-clock synchronization detail RP command to confirm.
Warning We recommend that you do not use these debug
commands without TAC supervision.
• Use the show network-clock synchronization command to confirm if
the system is in revertive mode or nonrevertive mode and verify the
nonrevertive configurations as shown in this example:
