Voice gateway ISR4451-X DSP issue, Calls are failing

Hello,

 

I have 2 voice gateways with 4 PRIs terminated on each gateway. VG router model is ISR4451-X running isr4400-universalk9.03.16.05.S.155-3.S5-ext.SPA. I am facing issue with DSP alarms/errors causing calls to fail (both incoming an outgoing). I have to reboot the VG router to restore the calling services. Then for 3-4 weeks or sometimes even for couple of months, it won't show any alarms/errors and then suddenly start showing them again. I had raised TAC and they suggested for IOS upgrade which has not resolved the issue. There is one TAC case in progress for the same issue but looks like Cisco engineers are not able to sort out the issue even though I shared all the logs.

I appreciate any help/suggestions on this issue.

 

 

Thanks,

Santosh

 

Here are the logs.

Did TAC ask you to setup any sort of DSP logging ? I see one of the cores in SOFT_RESET. If it happens again and again, it might be a bad PVDM as well.

Hi There are chances that you might be hitting this bug, one of the DSP is in soft reset state

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvd31107/?referring_site=bugquickviewredir

I would say confirm it with TAC.

Hi

The crashdump was recently enabled after getting those alarms and errors. I disabled it after TAC collected the required logs.

Thanks

Yes. Before suggesting for IOS upgrade, they enabled dsp debugging and captured the logs. But as per the TAC engineer, nothing came of out of it. They gave me some commands to run which actually were not working on 4451 router. Not sure if they even know the 4451 router exists :)

This defect seems relevant since you have an affected DSP firmware. Can you upgrade your IOS to a fixed release please ?

Hi Nipun,

 

I disabled the dsp crashdump as well but no luck. Looks like I would anyway need to upgrade the IOS. I will update once IOS upgrade is done.

 

Thanks,

Santosh

DSP crashdump is just a way to gather crash specific information/logs for your DSP's. It has nothing to do with the defect that I highlighted.
Yes, upgrade your IOS and monitor.

I found below command useful just in case if the dsp is stuck in SOFT RESET state.

 

test dsp device 0/1 1 reset  ; where 0/1 is dsp slot number and 1 is dsp id

 

After executing this command, that particular slot will be reset and the dsp failure will probably recover. I found that after reset; the dsp alarms stopped appearing in the logs

 

Mar 10 12:35:30.387: %DSPRM-5-UP_DOWN: DSP 1 in subslot 0/1, changed state to down

Mar 10 12:35:32.387: %LINK-5-CHANGED: Interface Service-Engine0/1/0, changed state to administratively down

That is just a software reset. If a reload/hard reset or DSP reseat does not help, software reset won't recover the DSP's. Usually it is worth a try before rebooting the router.

There is another command for soft reset. Not sure if there is any difference between reset and reset soft
test dsp device 0/1 1 reset soft

Effectively and at a high level they both are software based resets.

After soft resetting the dsp; the dsp alarms disappeared for almost 2 months now. I did not upgrade the IOS. Looks like the resetting works for me.
