We have 5 Switches, 2 x 2510G 24 Port and 3x2510 48 Port switches (layer2)
I set up the SNTP server address as one of our windows 2003 server (not a dc), time was sycing fine, since summer time change here in the UK (GMT) the time on the switches haven't synced / updated - it has on the windows 2003 server itself.
Do I need to reboot the switches in order to sync time ?
which command would one use to safely reboot the switch - "reload" ?
Thanks and Regards
Solved! Go to Solution.

Re: Time Sync - SNTP and Summer Time
The default value is fine (so just press enter).
For reference the default for "western-europe" is :
├в ┬в Begin DST at 2am the first Sunday on or after March 23rd.
├в ┬в End DST at 2am the first Sunday on or after October 23rd.

Re: Time Sync - SNTP and Summer Time
Hi Fiaz,
Thank you for explaining ; I went into configure terminal and typed the following command :
Switch-2(config)# time daylight-time-rule western-europe
and then the time sync, I didn't had to specify any dates or anything else just the command and enter.
do I need to do anyhing else or is this ok ?
Kind Regards

Re: Time Sync - SNTP and Summer Time
No, that's fine. At some point in the next 12 minutes (720 seconds) it should update.

Re: Time Sync - SNTP and Summer Time
Thanks for your assistance on all my threads so far.
a Quick question, I haven't rebooted the switches since install (more then 60days).
there are quite a few broadcast detected on ports for e.g. broadcast detected on port 13 (same ports almost everyday in the morning) when the user switches on the pc - I guess.
Also, I noticed CRC / Alignment Errors as well
Any thoughts on that - what should be done to get rid of these ?
