NTP on C2950 if you can help

Hi All,

I have read about NTP on Cisco link but I cannnot get it working on C2950's under the following setup.

I have 4 X C2950 connected to each other using Fibre Trunks. This is a dedicated LAN for CCTV. This particular LAN segment is independant and there is no other Layer 3 device. I am having problem to get NTP working. I have been trying to setup 2 or 3 of them as peer and point them to each other as I kbow they cannot be configured as NTP master. But when a switch is restrated it looses its time. Can someone help me by pasting some config hints ?



Re: NTP on C2950 if you can help

Try the different versions of NTP. Here is how you change the ntp version

in configuration mode

switch(config)#ntp server (ip address of ntp server) version (choose from 1-3)

Try them all and see if it will synk with the server

check your IOS is not lesser than 12.1(6)EA2c.

Also check whether you are able to ping the NTP server from the switch.

Use the

debug ntp packet

debug ntp valid

to troubleshoot the ntp packets.
