My switch was a Distribution switch.
I powered down the standby switch than problem went away. When i brought the switch back on, we started seeing the issue. I'd talked to TAC but did not help.
Here's what I did to fix the issue. I took out the secondary switch from the stack and added it back. Since than i've not seen the message.
When you take a secondary switch out from the stack, be careful, you are going to loose configs for the second switch. Just back it up and copy them back.
I hope this will help with your issue. Good luck

I have a 3750X switch stack(2 switches) using them as Distribution switch.
Sw2 is the master and Sw1 is member. From Distribution switch, we have multiple interfaces bundled as port-channel and uplink to the Core and access switches.
issue:
As soon as both switches are powered on, we are starting to see this message.
%SUPQ-4-CPUHB_SLOW_TRANSMIT: CPU Heartbeat Tx buffer not returned (switchname-1)
%SYS-3-CPUHOG: Task is running for (2312)msecs, more than (2000)msecs (682/129),process = Licensing Auto Update Process.
Also 1 or 2 times in an hour, it bounces all the active interfaces on Switch 1 for about 1 or 2 seconds. it comes right back on though..
Switches run fine for 3-4 hours than we starts to seeing vlan flapping than after 1-3 hours later, t brings the whole network down.
%SW_MATM-4-MACFLAP_NOTIF: Host 001b.d510.aba8 in vlan 100 is flapping between port Po1 and port Po3
while we are seeing vlan flap messages, we see this as well.
%HLFM-3-SEND_FAIL: Failed to send RPC message, req 3, -Traceback= 6C6788z 2EA60D4z 356FEB0z 3570730z 356D3CCz 356D520z 35659CCz 3561D4Cz
I power down the Switch 1 and everything works fine.
I created a TAC case but I can only work on this on a scheduled maintenance time. Maybe in couple days.
Anyone experienced this issue before? Any suggestion would appreciated.

I am planning to install CUCM and Unity Connection on BE6000 soon. Cisco Prime Unified Provision Manager app is required on the VM? I don't want to install it if it is not required.

We are in process of migrating to different ISP thus we have to change the Public IP Addresses. I have no issue changing inside and outside ip address but the servers in the DMZ are the issue. We want clients access the DMZ servers from new and current ISP than turn the current one off after about a month or so. My idea is assign new IP address for inside and outside interfaces and connect the DMZ in to the existing DMZ. current FW: inside: 192.168.1.1/24: vlan 192 outside: 10.1.1.1/24: vlan 10 dmz: 172.16.1.1./24: vlan 172 new FW: inside: 192.168.20.1/24: vlan 168 outside: 10.2.2.2/24: vlan 20 dmz: 172.16.1.2/24 vlan 172 do you see any issue configuring FW like this? ACL and NAT rule will be simlar where outside clients will be reaching the same DMZ servers using different outisde IP addresses. I have ASA5520 ie) 10.1.1.10 -> 172.16.1.10 10.2.2.10 -> 172.16.1.10

Jonathan, It has been awhile since i've messed with this. I think i made it work but the audio quality was not good. So I end up using fixed audio instead. If your CUCM is not on VM, i highly suggest to use this instead of MMOH. It is easier to manage and less trouble. If you are on VM than MMOH is the only option you have. Please note there is no multicast from your CUBE to the ITSP. CUBE receives multicast moh from the music source than it converts that stream to unicast than send it to ITSP. As long as multicast is working correctly, i think mmoh should work and make sure hold music stream uses G.711.

I am trying to upgrade our ASA5520(Primary/Standby) to 8.45. Can i upgrade 8.25 directly to 8.45 or do i have to upgrade to 8.3 first?

Thanks all for the help on this issue. Battling with CiscoTAC for many weeks, I finally figured out why I needed codec pass-thru on the CUBE. This bug was first found on the 8.5(1) CSCtw77944 Bug Details Codec pass-thru MTP is preferred over non codec pass-thru higher in MRGL Symptom: An MTP without codec pass-thru is not being selected first even though it is higher in the MRGL than a non codec pass-thru enabled MTP. Conditions: This will occur in call flows where none of the following conditions are met: 1. MTP required is checked. 2. There is no matching audio codec between two endpoints 3. Either endpoint's capabilities does not include any codec that this within region BW limit Workaround: This is working as designed. Codec pass-thru MTP's are preferred in this case so that video, SRTP, or T38 can potentially be negotiated later in the call. If the desired behavior is to use a non codec pass-thru MTP primarily, then remove all codec pass-thru enabled MTP's from the device's MRGL as well as the default MRG.

I can send traces and config tomorrow. I forgot to mention. I am using separate cube for production and codec is set to g711. Sent from Cisco Technical Support iPhone App

phone<------->iosmtp=g729 phone<--------------->cucmmtp=g711 phone<--------------->siptrunk=g729 siptrunk<-------------->cucmmtp=g711 On my MRGL, cucmmtp and iosmtp are not in the same mrg. it always invokes cucmmtp unless i changed the phone region setting to cucmmtp to g729 than it uses iosmtp. it doesn't matter which order I list in the MRGs in the MRGL, it always uses cucmtp unless I add codec pass-through in the CUBE or change codec to cucmmtp. I also tried making outbound calls in our production phone that are using all g711 codec but it still does not invoke iosmtp. below is the region setting for my production phone. phone<------->iosmtp=g711 phone<--------------->cucmmtp=g711 phone<--------------->siptrunk=g711 siptrunk<-------------->cucmmtp=g711 This is too weird.... I created a TAC case but they are still haven't figure it out yet.

Thanks for your reply aokanlawon. I am almost tempt to create a second region but i would like to understand this first. The phone i am using to test and IOS sw MTP are on the same Region and it is using g729. Server MTP is on different Region which it uses G711. See below Region: -Server MTP -SIP_Trunk Media Resources: -Server MTP: --- Region: Server MTP -IOS sw MTP: --- Region: SIP_Trunk Region setting for the phone i am using to test: Phone region: g711 Server MTP: g711 SIP_Trunk: g729 CUBE setting: dspfarm profile 20 mtp codec g729r8 maximum sessions software 500 associate application SCCP MRGL: -IOS sw MTP -Server MTP Above is the setting i have on my system. When i make outbound calls, it always invokes Server MTP.. unless i change the Server MTP region to g729. What you are saying is this is normal? Per above configuration, isn't the phone supposed to invoke IOS sw MTP first?

I am glad I am not the only one who is having this issue. What you just described makes sense. We wanted to insert IOS mtp for our Type A phones.. ie) 7940 and 7921 WL phones because we have tons of 7940s at one of our remote site and we are just about to convert them to the SIP Trunk service and requirement is to use g729 instead of g711 codec. When I configure codec pass-though, everything works fine. Here’s what I discovered while I was testing. When I changed the region where Server mtp is on to g729 from g711, it starts invoking IOS mtp however Conf and MOH is on that region and when you try to create a conference call, it is going to invoke xcode. It looks like we are hitting a CUCM bug, in this case, can I leave codec pass-through under the dspfarm profile mtp? Is this going to cause any issues?

I have cucm 8.51 and cube. I have iOS software mtp configured on the cube. Question is this. When i add codec pass-through under the dspfarm, cucm invokes correct mtp which is ios sw mtp but when I remove the command it always invokes the server mtp. Is pass-through command required command? Per cisco TAC the command is not required but when I remove it cucm always invokes server mtp. When do you use codec pass-through? I am not using RSVP. If I leave the command it is not going to cause any issues? Below is my config. Dspfarm profile 20 mtp Codec g729r8 Codec pass-through Maximum session software 500 Associate application SCCP Thanks for your help
