Problem with NTP setting on Cisco-Nexus3064

[serzh-gaziev]

Hi everyone. I have a problem with ntp settings on this device:

version 7.0(3)I7(6) Bios:version 4.5.0
ntp server 192.168.1.14 use-vrf default
ntp source-interface Vlan2020
clock format 24-hours
ntp access-group serve ntp-server
ntp access-group serve-only ntp-server
ntp access-group query-only query-ntp-acl
feature ntp
no ntp allow private
no ntp allow control
no ntp passive

IP access list ntp-server
10 permit ip 192.168.1.14/32 any
IP access list query-ntp-acl
10 permit ip 192.168.1.14/32 any

That`s all settings about ntp.

show ntp peer-status:
Total peers : 1
* - selected for sync, + - peer mode(active),
- - peer mode(passive), = - polled in client mode
remote local st poll reach delay vrf
-----------------------------------------------------------------------------------------------------------------------
=192.168.1.14 192.168.1.27 16 64 0 0.00000 default

Stratum is 16 and ntp isn`t working.

But on other device with version 7.0(3)I4(6) that`s all settings are working.

 - Could be a bug as in : https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvd00648

   The latter not your specific platform, but as a test I would remove all access-directives on the ntp settings ,and start by defining a bare-ntp server (only). Check what happens then.

When i delete these 3-lines, that is all work:
ntp access-group serve ntp-server
ntp access-group serve-only ntp-server
ntp access-group query-only query-ntp-acl

Is there mistake?

When i delete these 3-lines, that is all work:
ntp access-group serve ntp-server
ntp access-group serve-only ntp-server
ntp access-group query-only query-ntp-acl

what you mean by this, so your NTP Server work as expected ?

where is this ACL applied ? do you have ACL incoming and out going example for NTP

example :

access-list 101 permit udp any any eq 123
access-list 101 permit udp any eq 123 any

i have these mistake in logging:
%VSHD-2-VSHD_SYSLOG_EOL_ERR: EOL function ntp_cli_config from library libntpwd.so exited due to Signal 11

Hello,

on IOS devices, it used to be that sometimes you would have to manually set the clock initially, to something very close to the actual time, which would then make the device synchronize, you could try the same on the Nexus:

NX3064(config)# clock set 08:43:00 15 sep 2021 <-- make sure that what you enter is close to the real time...

Thank you for your advice. But NTP not working. I set the device:
clock protocol none
clock set 09:48:00 15 sep 2021
clock protocol ntp
exit
ntp sync-retry
