Configuration for NTP Server

Hi

I have 6506 CORE with 2 Modules of L3.

I want to configure NTP server on it.

I have already set the time zone & time on both L2 & L3.

Following is my output on one of the L3 Module.

Please sugget me the forward path.

6506_L3_A1#sh ntp status

Clock is unsynchronized, stratum 16, no reference clock

nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**24

reference time is 00000000.00000000 (05:30:00.000 IST Mon Jan 1 1900)

clock offset is 0.0000 msec, root delay is 0.00 msec

root dispersion is 0.00 msec, peer dispersion is 0.00 msec

6506_L3_A1#sh ntp a

6506_L3_A1#sh ntp associations

address ref clock st when poll reach delay offset disp

~172.16.1.2 0.0.0.0 16 - 64 0 0.0 0.00 16000.

I doubt if the 6500 has this capability

ntp update-calendar

ntp server xxx.xxx.xxx.xxx

ntp server xxx.xxx.xxx.xxx prefer

You can enter the above commands filling in the xxx's with the IP address of the server in which you will be receiving the time.

I think he wanted to make the 6xxx the server...but i could be wrong.

Re: Configuration for NTP Server

Are you running Native or Hybrid? AFAIK NTP will only work with Native.

Can you ping the NTP source? Are you permitting the udp 123 port?

What show ntp associations detail says?

Hi Thanks.

I don't know Native or Hybrid....

Following is the output of show ntp associates from one of my L3 module. Please help me out.

Re: Configuration for NTP Server

lets get some clarification. Are you attempting to make the 6509 the NTP server ? If so, I don't think that will work.ou will need a server configured to broadcast NTP, or bring in in from an ntp server on the internet.

Once that gets sorted out the rest is easy.

Re: Configuration for NTP Server

One of our router was configured as NTP Server & I have configured the same in my 6506 CORE. Now the 6506 is synced with the master.
