Symptom: Priority packets fall under class-default

Conditions: Channelized interface VWIC
Tested a hwic-1t and build-in Gig Int, no issue.
Workaround: Change the queueing policy from priority to bandwidth results in the problem no occurring or using just the queueing policy and removing the shaping policy results in the problem not occurring.
Further Problem Description: There is a clear interaction between channelized interfaces and QoS.

Definitely a code problem. Short version: after many weeks of chasing them, Cisco dropped in a test version of IOS code. Problem cleared. Cisco asked to remove test code, problem came back. We are waiting for Cisco to release a mainline version with the fix. According to the emails:
They have committed the fix to the following images: 15.6(2)T1 and 15.4(3)M6
cco release date (15.6(2)T1) is 6/21/2016
cco release date (15.4(3)M6) is 7/29/2016
The same fix will be committed to other versions like 15.5 and 15.6M but they will published by Sept or Oct this year. Looking for bug ID...

2911 - 15.2(4)M6a - T1 WAN
I'm having difficulty figuring out why I get intermittent ef marked packets in the class-default queue. The matched voice ACL (UDP based port range) counters agree with the realtime counters exactly.
#sh policy-map int gi0/0 in GigabitEthernet0/0
Service-policy input: MarkInbound
Class-map: MarkVoice (match-any) 189681 packets, 19213876 bytes 30 second offered rate 0000 bps, drop rate 0000 bps Match: access-group name VoiceDataACL 189681 packets, 19213876 bytes 30 second rate 0 bps QoS Set dscp ef Packets marked 189681
sh ip access-lists VoiceDataACL Extended IP access list VoiceDataACL 10 permit udp any range 16384 32767 any range 16384 32767 (189681 matches)
sh policy-map int se0/0/0:0 out class class-default
<truncated output>
Class-map: class-default (match-any) 1784475 packets, 1527263608 bytes 30 second offered rate 75000 bps, drop rate 0000 bps Match: any Queueing queue limit 64 packets (queue depth/total drops/no-buffer drops) 0/100005/0 (pkts output/bytes output) 1786915/1455101962 bandwidth remaining 4% Exp-weight-constant: 9 (1/512) Mean queue depth: 0 packets dscp Transmitted Random drop Tail drop Minimum Maximum Mark pkts/bytes pkts/bytes pkts/bytes thresh thresh prob
default 1772601/1453731273 8331/9553582 91453/124110423 20 40 1/10 ef 14314/1370689 3/472 218/34293 36 40 1/10
The problem is manifested on WAN calls where the far end hears degraded voice quality, but the near end has no problems. How can ef marked packets get queued in the class-default class-map?
This same config is present in dozens of other routers, but this one site is the only one with errant ef packets.
I appreciate any help.

Customer has a virtual CUCM, CUC & CUP environment running on 2 hosts in the same chassis. CUC & CUP are misbehaving due to known CPU utilization bugs and will be upgraded to latest SU. Question is what to upgrade first? CUC is the most unstable, so upgrading it first was my initial thought, then CUP and CUCM last. Is there any reason to change this order of updates? CUCM 8.6(2a)SU2 update to 8.6(2a)SU5 CUC 8.6(2a)SU3 update to 8.6(2a)SU5 CUP 8.6(5) update to 8.6(5)SU3 I appreciate it, Beau

Thank you both. Mark - it works as expected pulling devices with user & network hold file names. Brian - this too works to pull the pattern's associated MoH file name. I've used them both and verified the syntax.

CUCM 8.6.2.22900-9 Has anyone performed an SFDC integration using SimpliCTI's connector? http://www.simplicti.com/web3/content/view/79/37/ I've got a 10-digit dial plan that we're trying to figure out how to differentiate between on-net & off-net calls. Short of building RPs covering all my DIDs, not sure how to go about it. Any ideas? Thanks.

Yes, I'm aware of this option. I'm looking for a CLI SQL query to capture enough detail to determine which templates are not in use, or in limited use. A similar string would be from this post: https://supportforums.cisco.com/message/3541921#3541921 Thanks, Beau

Does anyone have a CLI query string built for retrieving phone button template dependencies? I'd like to determine how many unused phone button templates there are, and how many phones use each template. CUCM 6.1 (or any other version) Thanks, Beau

Is there a way to retrieve the 'Extension Mobility Dynamic' record for a large list of UDPs? The intent is to generate a list of UDPs that haven't been used in some time, and flag them for removal - as well as being able to track which device a user is logging into. If there is a better process for finding these, I'll be happy to learn it. CUCM 6.1 & up Thanks, Beau

Is there a requirement for the SNMP community string CER (7.1.1.3000003) uses with CUCM (6.1.5.12900-7)) to be RO exclusively, or can an RW string be used as well?
