Summit X-Series, Problem with curent time

[Carsten_Volmer]

Hi, at all!

We have a problem with some switches x450 with the firmware 22.2.1.5 and higher. We configure the timezone with this syntax:

"configure timezone name MEZ 60 autodst name MESZ 60 begins every last sunday march ends every last sunday october"

But when I show the current time with "show switch", there is a difference about 20 or 30 minutes.

What's the problem and how can I solve it?

Thanks for all answers!

SOLUTION!!!

We found a solution for that problem. We had to add the transfernet with the syntax

enable NTP vlan [Transfernet]

and then the sending IP was added as the local interface.

Thanks for everyone, who sehnd an answer!

Hi, Brandon!

# Module ntp configuration.
#
enable ntp vr VR-Default
enable ntp vlan [VLAN ID]
configure ntp server add [Server IP] burst vr VR-Default

Another Information:

We have Summits which are simply L2-switches. There NTP is OK. I can see the MGMT-IP as the local interface. The Switches who are L3 - Switches, theres is no NTP Funktion. There is not the MGMT-IP the local IP. You can see ist above. There is no local interface. The NTP Server IP is reachable on every Switch.
