HP A3100 - NTP unsynchronized

Hi,

 

We installed a switch HP A 3100 on a branch site. This switch only has one interface Vlan in order to be manageable.

We wanted this branch switch to synchronize its clock with a server on the Main Site using NTP. 

 

Branch site switch has the following IP adress : 10.31.7.251

Main Site NTP serveur IP adress : 10.31.248.11

 

We used on the branch switch the command : ntp-service unicast-server 10.31.248.11

 

This NTP server appears when we do : dis ntp-service sessions

 

However the clock is not synchronized when we do : dis ntp-service status

We can ping the NTP server from the branch switch.

 

We ran the command : debugging ntp-service all

 

Here is what we got :

Any idea ?

 

Thanks.

If you dont reside in UTC, have you set the timezone? clock timezone <xxx>
