CnMatrix SNTP Unicast-Server UDP Port via cnMaestro

Running into a bit of an issue, as I cannot seem to sync NTP time to a CnMatrix switch deployed via CNMaestro.

There seems to be a bug in the switch group for SNTP.When deploying SNTP settings the outgoing udp PORT seems to default to 1029 and not 123 from what I can tell , and I cannot see any TZ settings being applied.

show sntp unicast-mode status
auto discovery of sntp/ntp servers is enabled
unicast poll interval value is 64
unicast max poll time out value is 5
unicast max retry time value is 3
unicast current mode value is NOT SYNCHRONIZED
sntp client is up for 00:07:46
unicast primary server host name is pool.ntp.org
unicast primary server version is 4
unicast primary server port is 1029
Num sntp-client req-msgs transmitted to the primary server 3

show running-config sntp

# Building configuration...
# Software version: 3.2.1-r5
# Model Name      : cnMatrix EX2028-P
!
sntp
set sntp client enabled
set sntp unicast-server auto-discovery enabled
set sntp unicast-server domain-name pool.ntp.org port 1029
!
end

Of course right after I submit the post, it start syncing :slight_smile: Seems to just take its sweet time.

One thing that doesn’t seem to work is the timezone setting.Doesn’t seem to affect timing at all and I can’t find any trace in the config that it alter the clock setting.Seems to be stuck on UTC 0

Hi Marius,

We were able to reproduce the issues related to SNTP and have fix currently being tested by our QA team. I will reply back once we have the servers updated with the fix. Thanks for listing out the issues.

Hi Marius,

The fix is available from 3.0.0-r44 build onwards and has been updated on production cloud.
