CUE will not sync time with CME

Unanswered Question

I currently have a UC520 system that CUE time is incorrect on by 5 hours. I have set the time with both Configuration Assistant (the most current version) and from the command line. Last night I also attempted to set the ntp server while logged into CUE and get messages that follows:

UC500-CUE(config)> ntp server

WARNING!!! Could not reach using NTP.

WARNING!!! might not have been configured as

WARNING!!! NTP server.

WARNING!!! NTP Server Will be entered in the NTP List

IP address: is the CME side of the UC520

Save the change to startup configuration and reload the module for the new timez

one to take effect.


I have rebooted the system and the time is still off. Additionally I was not able to find any other way in documentation to set the time manually in CUE. I don't really know where to go from here. Any help or advise, Thank you,

Here are a couple of items to check.

1. Can you ping from the CUE module?

2. Check your timezone in CUE

3. Check for the "ntp master" command in CME

4. There is a bug relating to this issue - CSCsu36827. Check the link below to see if this applies.

Hope this helps.



Thank you for your quick reply.

Yes you can ping from CUE.

In my first post that was me setting the Timezone on CUE to Pacific which was also done last night without results.

On CME I set it to have an NTP server prefer and then the NTP master was also set. I then set CUE to use CME as the NTP server and got the error at the beginning of my first post. I left it over night and time is still incorrect.

I will check the Bug you linked and get back to you as soon as possible.

Thanks again,


Ok, further update, I have read the Bug link and attempted to ping an external ntp server, however from CUE I am only able to ping the CME and no other IP addresses. I think this is the problem. When pinging the Domain controller local ( I get Destination unreachable reported by the CUE. I also get the same response when pinging the IP address for 1 A Any ideas of how to resolve.

Thanks again.

Does your CUE module interface have a default gateway. Sounds like a routing problem.

Apologies for using this thread to pass a message to Brandon but the new site is proving slightly problematic.


Don't know whether you got my response from invite a friend. Collin Clark also invited me but the e-mails are not working properly so whenever you or Collin try to e-mail me apparently it just goes back to Dan using the [email protected].

Just didn't want you to think i was ignoring you in case you didn't get response.

     I received a couple of messages from you yesterday. One appeared as if it was meant for Collin. I don't think you can reply directly to an email message. I think you have to go back to the site and email from there. However, I haven't seen a way to email you. Could be because your email address is hidden and mine is not?

In the CME config, you should see something similar to:

interface Service-Engine0/0
ip unnumbered GigabitEthernet0/0
ip nat inside
ip virtual-reassembly
service-module ip address
service-module ip default-gateway



This is from the configuration:

interface Loopback0

ip address

ip virtual-reassembly


interface FastEthernet0/0

ip address dhcp client-id FastEthernet0/0

ip virtual-reassembly

duplex auto

speed auto


interface Integrated-Service-Engine0/0

description cue is initialized with default IMAP group

ip unnumbered Loopback0

ip virtual-reassembly

service-module ip address

service-module ip default-gateway

Is CUE pointing to for NTP? Is this router NATing traffic out to the internet? If so, and you want CUE to point to an external NTP server, I believe you will need "ip nat inside" on the service engine interface.



CUE is not pointing to for NTP and when I set NTP to it I also get the error message saying NTP server could not be contacted. I set ip nat inside on the interface as suggested and this also has not resolved the problem. This router is not routing traffic to the internet there is a PIX locally on the same subnet as the router. It's IP address is

I do not have access to any other UC520 systems to compare configuration too. Any other help or ideas for me to check out would great.

Thank you again for you help so far.

OK. If there is another device connecting to the internet and doing NAT, you will not need the nat statement on the CUE interface. Is the PIX setup to NAT addresses in the subnet to the internet? Is the CME getting NTP (show ntp status)?



I don't believe the PIX is setup to nat the address space.

Here is the output from CME ntp status:

ColRheumUC520#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**32

reference time is CEB17784.2B1E292A (12:16:04.168 PST Fri Nov 20 2009)

clock offset is 0.0000 msec, root delay is 0.00 msec

root dispersion is 5.13 msec, peer dispersion is 0.00 msec

loopfilter state is 'CTRL' (Normal Controlled Loop), drift is 0.000000000 s/s

system poll interval is 64, last update was 342049 sec ago.

Does not seem to be sync'd. However my question is shouldn't CUE time itself from the CME? Time is correct on CME though manually set at this time.

Thanks again

Can you ping from CME?  Can you re-post the current "sh ntp status" from CUE?

You have a routing issue from your CME to the Internet and therefore you will not be able to contact outside time source for your CME.  You can set routes on your router/firewall to fix this issue.  As Brandon pointed out, you need to be able to ping from CUE.  Please verify and use the following config in your CME.

ntp master

ntp update-calendar

ntp server

as for your CUE config, make sure you have the following in place

no ntp server

no ntp server

ntp server prefer

After this is in place, restart CUE and your time will sync with the CME time.

The fix for this is fairly simple:

go here:

Look for the link: UC500 Software Download - Cisco Smart Business Communications Systems

Accept the agreement, enter your CCO information:

Look for the most current download for your UC500 system and update the system to the most current software load.

Lots of fixes to multiple problems with the UC500 systems are solved by upgrading them.

The most current update changed the older UC500 system way it handles timing itself.

Problem solved:

Good Luck,
