Nexus9K NTP issue

n-86
Level 1
Level 1

Hi everyone,

I have a problem with NTP on our Nexus9k.

I have changed ntp configuration from:

ntp server 10.20.1.1 prefer use-vrf management
ntp server 10.20.1.2 use-vrf management
ntp source-interface mgmt0

to this:

 

ntp server 10.10.1.1 prefer use-vrf management
ntp server 10.10.1.2 use-vrf management
ntp source-interface mgmt0
ntp logging

and after that i seeing that nexus switch not sync properly time with ntp servers(i'm not shure what mean 'polled in client mode' but i think it should be 'selected for sync'):

 

nexus02# 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

=10.10.1.2                              10.1.18.9                               2   64     377   0.04260management

I can reach ntp servers using mgm0 interface as source:

 

nexus02# ping 10.10.1.1 source-interface mgmt0
PING 10.10.1.1 (10.10.1.1): 56 data bytes
64 bytes from 10.10.1.1: icmp_seq=0 ttl=253 time=42.777 ms
64 bytes from 10.10.1.1: icmp_seq=1 ttl=253 time=42.54 ms
64 bytes from 10.10.1.1: icmp_seq=2 ttl=253 time=42.735 ms

nexus02# 
BIOS: version 05.33
NXOS: version 7.0(3)I7(6)

Maybe you know the reason of that behavior and will say me what i made incorrectly. Thank you in advance.
