Alcatel Unleashed

Hello,

I’m asking this question because I’ve already had this problem.

I’d like to know if there’s a way for the switch to keep the date and time configuration on each reboot, since I don’t have an NTP server on the network.

Another question: Is it possible to configure a switch as an NTP server for other switches?

We have two OS6865-U28X core switches and OS2360-P24/48X edge switches.

Thanks for your reply.

Hi,

not sure if the switch has a RTC-module that would keep the time sync during a reboot.
For the NTP, as far as I know the NTP-Server should be enabled by default you can check with and enable with The switch that should sync would need At least on my OS6860-switch it works that way.

Best Regards

Thanks for your reply.

I've got the NTP server active, it sees the client request but doesn't retrieve the date and time info...

On the core :
SURETE|COEUR [U1&U2] -> sh ntp server client-list

On the distribution switch :
sSURETE|SR02 [U1&U2] -> sh ntp status

SURETE|SR02 [U1&U2] -> sh configuration snapshot ntp

Hi,

had a look in the mgmt-guide:

To disable an NTP client from invoking tests for NTP server synchronization, enter the ntp server
unsynchronized command, as shown:

->

Code: Select all

ntp server unsynchronized

Disabling peer synchronization tests allows the NTP client to synchronize with either an NTP peer that is
not synchronized with an atomic clock or a network of NTP servers that will finally synchronize with an
atomic clock

So I guess this command is needed on the distirbution switch, as the core switch does not sync with a atomic clock or other NTP-server.

Regards

I've tried this command, but I don't think it exists on OS5...

the ntp option unsynchronized isn't available anymore (since 3...4 years). This means that the used ntp server (f.e. other switch) needs a connection to a ntp source with better than stratum 16.

So whatever happens, I need an external NTP server.
