CUAE2.5 Beta + CUCM 7.0 CiscoDeviceListX stucks at "refreshing device list"

Hi guys,

I have a newly installed CUCM 7.0 and CUAE 2.5 beta, I've configured the SNMP string the same way as it should be done in CUCM 6.0.

Right after I configured my call manager cluster in CUAE, I turn to "CiscoDeviceListX", try to invoke the extension "Metreos.Providers.CiscoDeviceListX.Refresh", and then I got a line of message like this in Appserver log:

"Info: CDL Device list cache refresh starting."

Things just hang there, I kept waiting and waiting, there's no response.

I've tried to restart CM SNMP service and CM CTI Manager, still no luck.

It is blocking me and quite urgent, any highlight on it will be greatly appreciated. Thanks a lot!

Best Regards,

I'm pretty sure CUAE 2.5 beta installation is a success one, because this "CiscoDeviceListX" provider works perfect with a CUCM 6.0.

Thanks & Regards,

Can you walk the CM7 phone table using a direct SNMP tool?

If not, I'd pursue that via your CM7 EFT support avenue.

If so, grab a network packet capture of a successful CM6 update and a failure CM7 update for comparison.

Hi David,

Thanks for pointing out the way.

Could you please be a little more specific about "CM 7 phone table"?

I'm not sure what table I should look up exactly. I've used WireShark and found that the "getBulkRequest" was sent to :
name: 1.3.6.1.4.1.9.9.156.1.1.8.1.2.0 (SNMPv2-SMI::enterprises.9.9.156.1.1.8.1.2.0)

And the response is:
==================================================================================
No. Time Source Destination Protocol Info
19 9.232356 172.16.201.103 172.16.201.45 SNMP get-response

So I assume I should look up the table 1.3.6.1.4.1.9.9.156.1.1.8.1.2.0 in SNMPv2-SMI MIB?
If that is the case, then there's no table in SNMPv2-SMI MIB at all according to my SNMP walker tool.

Many thanks to your help.

Hi David,

I think I must have looked at the wrong place, because there's no table in SNMPv2-SMI MIB for my CUCM 6.0, but the CiscoDeviceListX do get the device list.

Could you please tell me which table the CiscoDeviceListX is querying using SNMP or just show me how/where I can get such information?

Thanks & Best Regards,
Ruwei

I believe CUAE pulls its real time device info from the CISCO-CCM-MIB:

/ciscoMgmt/ciscoCcmMIBObjects/ccmPhoneInfo/ccmPhoneTable

.1.3.6.1.4.1.9.9.156.1.2.4

Hi David,

Thanks a bunch! You've been a great help.

The whole "enterprise" MIB(.1.3.6.1.4.1) is missing in my CUCM 7.0.

One of the critical services keeps going down and the CPU load reaches 95% on my server machine. So I guess that's the root cause since there's no obvious error messages in the installtion log.

Best,
Ruwei
