Validation
Normal Time synchronization is not affected.
Check the local clock synchronization in the NTP Master as mentioned below:
VTEP1#show ntp peer-status
remote refid st t when poll reach delay offset jitter
==============================================================================
*127.127.1.0 .LOCL. 1 l 40 64 377 0.000 0.000 0.000
VTEP1#
Check the ntp client1 synchronization status as mentioned below:
#show ntp peer-status
Total peers : 1
* - selected for sync, + - peer mode(active),
- - peer mode(passive), = - polled in client mode,
x - source false ticker
remote refid st t when poll reach delay offset jitter
==============================================================================
*10.12.20.5 LOCAL(0) 2 u 13 16 377 0.180 0.019 0.013
Check the ntp client2 synchronization status as mentioned below:
VTEP2#show ntp peer-status
Total peers : 1
* - selected for sync, + - peer mode(active),
- - peer mode(passive), = - polled in client mode,
x - source false ticker
