4000 not synchronizing time via ntp

I have set up ntp on my 6509's and they are retrieving time from the atomic clocks on the internet. I am now tring to synchronize one of my 4000's from the 6509's, but it won't update. the config is as follows:

ntp source Vlan248

ntp server 10.235.251.202

ntp server 10.235.251.201

The associations are as follows:

address ref clock st when poll reach delay offset disp

~10.235.251.202 0.0.0.0 16 - 64 0 0.0 0.00 16000.

~10.235.251.201 0.0.0.0 16 - 64 0 0.0 0.00 16000.

* master (synced), # master (unsynced), + selected, - candidate, ~ configured

What am I missing?

Thanks!!

Re: 4000 not synchronizing time via ntp

If you're 6509 must act as a ntp-server, you must add the command ntp master

Re: 4000 not synchronizing time via ntp

The 6509 is Cat OS based and there is no command for ntp master. See the following response to my query from the 6509:

set ntp ?

authentication Enable/disable NTP authentication

broadcastclient Enable/disable NTP Broadcast client

broadcastdelay Set NTP broadcast delay

client Enable/disable NTP client

key Set NTP authentication key

server Set NTP server information

summertime Set summertime

timezone Set time zone

Re: 4000 not synchronizing time via ntp

I thought the cat6509 was running native-ios. Maybe the document below can help you out for configuring ntp on catos:

Re: 4000 not synchronizing time via ntp

The switch is running Cat OS but the msfc is running IOS. Your post caused me to look in a new direction. I set up ntp on the msfc and set it to be master. I then changed the config in the 4000 to get the time from the msfc and it synchronized.

Thanks for your help.
