If you are wanting to set it manually, please issue the clock set command.

Otherwise, you can also set it to communicate to an NTP server to get time synched to NTP.

I hope this information helps you.

HI Edadios,

Thanks for your reply. Please advice me for below also

To use the NTP

ntp << Server IP>>  is this enough or i need to give ntp authentication and ntp trust_key also..

In my switches i can see  ntp> only..

Thanks

Hi Tamilvanan,

If your NTP server does not require authentication, you can just specify the 'ntp server' command. Here is a link to the configuration guide for NTP for your reference:

Hope that helps.
