CUCM NTP - what will happen?

[lukeprimm]

I just realized that the NTP server our CUCM cluster is pointing to was decomissioned about 8 months ago (it was a 2003 Windows server box).  Somehow our phones have maintained accurate time???

I need to update the NTP server and I think I found where to do it, though I want to make sure its not going to have adverse effects on the system and phones?

Any help?

CUCM 7.1.3b

thanks

You can change the NTP server on the OS admin pages

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cucos/7_1_2/cucos/iptpch4.html#wp1042131

This will propogate a time change on your phones.

If your existing server reference is offline your CUCM will be using

the onboard system clock from the physical server

so in theory, if the time is right already, there should really bo no noticeable change?

You can check your current ntp status by using the

Putty SSH console

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cli_ref/7_1_2/cli_ref_712.html#wp42375

utils ntp status

and change here to with

utils ntp configure A.B.C.D

No noticeable affect

thanks, im embarrassed but I cant figure out what username and password to use to SSH into the box? I tried all of the different Call manager log and passes, any ideas which one is used to SSH?

thanks

Luke,

This is the same OS Admin UID & password from the CUCM admin page

If you are on the web page for CUCM Admin in the top

right there is a drop down

CM Admin
