I am trying to set the British Day Light Saving on the 8600 and have worked out the below commands using ACLI:

boot config tz name GMT
boot config tz dst-offset 60
boot config tz dst-start 03310200
boot config tz dst-end 10270100

We are running 7.2.1 on our 8600’s and using ACLI.

Are the above commands correct?
After you run these commands do you need to restart the switch? (It says in the documentation to restart the switch)
Do I need to run these commands every year?

Your assistance will be appreciated.

Meraj

I almost missed your second post… you should use a DNS alias, then you only need to update the DNS pointers.

Hi Gregg,

The ERS 8600 can only function as a NTP client – at least up to 5.1.x software. I’m not 100% sure of 7.x software.

Cheers!

Or at least have it forward NTP client requests to a remote NTP server. That way I would only have to change the NTP server address in my core switches instead of changing the address in every device. Thank you very much!!

Hi Joe,

Yes you do… similar to Cisco behavior although in 6.2.x software for the Avaya Ethernet Routing Switch 5000 series you no longer need to stipulate the year.

Good Luck!

Hi Lay,

The hardware time will always be in UCT format. It’s the local time that is used in the logs and all operations that will be reflective of the timezone that the equipment is located in.

Cheers!

I have configured NTP on Nortel ERS 8010 as per your suggestion and it works. Thanks much for your sharing. However, is there any way to keep local time and hardware time the same. Following is my output and I got the right local time while the hardware time show the UTC time since my NTP server just gives UTC.

ERS8010# date
local time: WED JUL 14 16:17:54 2010 WST
hardware time: WED JUL 14 08:17:54 2010 UTC:

And, this is my NTP config in ERS 8010 switch.
config bootconfig tz name “WST”
config bootconfig tz offset-from-utc -480
config ntp server create A.B.C.D

config ntp enable true
config ntp interval 15

Thanks in advance for your advice.

I’m pretty new to Nortel coming from mainly a Cisco background, do you have a any pointers for finding config guides, cli guides, decent books etc. I find searching for information on Nortel’s site pretty painful. Any pointers would be greatly appreciated. Thanks.

You might want to try and upgrade the software, it could be a bug.

Hi Prince,

What switch model and software release are you working with?

Cheers!
