Forgot to add the documantation: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/12-2_55_se/configuration/guide/3560_scg/swadmin.html#pgfId-1298137

Hi vic

You need to  define a name server before the lookup will work for 1.ch.poo.ntp.org.

ip name-server 8.8.8.8

And the ntp server 1.ch.pool.ntp.org will then resolve the DNS name and put the ip address in the configuration.

It can take several minutes for the sync to take place.

show ntp stat  ! shows synconization time

show ntp asso  ! show if the sync is working

You still have to change the timezone with:

clock timezone MyZone -3 0
clock summer-time MyZone recurring last Sun Mar 2:00 last Sun Oct 2:00

thanks for your fast answer!

i have added

clock timezone EET 1

clock summer-time  EEST recurring last Sun Mar 2:00 last Sun Oct 3:00

---

and the time is no right

why do i have to add a 1 behind EET?

on a cisco page i found

EET	Eastern Europe Time, as UTC + 2

Hi

The 1 means UTC +1. So in your case it would be EET 2.

-5 means UTC -5 hours and so on.
