Cisco Nexus 3172 NTP

[Jean-Francois Gagnon]

Hello!

I'm trying to make the NTP synchronisation work by the management interface and vrf. 

Here's my config that does not work:

It doesn't even seem to get started at all... 

clock protocol ntp vdc 1
ip access-list copp-system-acl-ntp
10 permit udp any any eq ntp
20 permit udp any eq ntp any
class-map type control-plane match-any copp-ntp
match access-group name copp-system-acl-ntp
class copp-ntp
ntp peer X.X.X.1 prefer use-vrf management
ntp peer X.X.X.2 prefer use-vrf management
ntp source-interface mgmt0

N2(config)# show ntp status
Distribution : Disabled
Last operational state: No session

 
N2(config)# show ntp peer-status
Total peers : 2
* - selected for sync, + - peer mode(active),
- - peer mode(passive), = - polled in client mode
remote local st poll reach delay vrf
-------------------------------------------------------------------------------
+Peer1 ManagementIP 16 64 0 0.00000 management
+Peer2 ManagementIP 16 64 0 0.00000 management

Thanks for your help

Hi
try ntp server instead of peer and is feature ntp enabled too

[Jean-Francois Gagnon]

I tried both. When using ntp server instead, peers show in default vrf.

And yes, ntp feature is already on.

Thanks

alol i have on my nexus switches is ntp server x.x.x.x use-vrf management

what does the sh clock details command show is NTP enabled

[Jean-Francois Gagnon]

hum yeah your right.

What do you get with show ntp status ?

[Mark Malone]

same disabled but thats NTP distribution , once the clock source is NTP your good

[Jean-Francois Gagnon]

Well it does seem to work. And I think somehow in my troubleshooting I was not looking at the good status.

Thanks for your help!
