Solved: LMR integration 4321 versus 2811 (NIM / VIC2 - E&M Cards)

goliver · ‎08-27-2018

Hi,

We use the ISRs to get radio traffic through E&M ports with LMR out to the network via multicast (exactly the same config you would use in an IPICS deployment).

We have always used 28/29xx series up until now and they are being swapped for 43xx series now. These routers do not wirk with the exact same config on them though. The IOS XE originally shipped did not even support multicast dial-peers out of the box and I have since upgraded to the latest (including the fuji and denali trains) with no success. The config is simple ::

I usually debug with "vpm signal" on the older models, but the debugs do not even look the same to me on this new one and I am not getting the usual things I would see on a 2800 when e-lead traffic is generated from the handheld.

Is there something I am missing on these new XE routers? A switch that needs to be flipped somewhere? These NIM-4E&M modules are the only ones I have, so I am unsure if other voice cards have this same issue.

Thanks,

Greg

goliver · ‎03-02-2019

Sorry, I know it has been a while, but I did want to finalize this one out for the records and future searches.

The issue was that the NIM Service-Engine configurations *also* need PIM defined on them. TAC fixed it fairly quickly, but I wanted to share it here as well.

Add PIM under the service-engine and then test.

goliver · ‎08-28-2018

Hi Nipun,

Thanks for the reply - unfortunately, it is still not working. This raises a couple of questions though -

1. if the NIM is now housing the DSPs (I read that each voice NIM has it's own DSPs), is the vif still required?

2. I assumed the service-engine that has the same numbering as the NIM is the one to add PIM to - in this case 0/1/0, so service-engine 0/1

Did I get that correct? I tried adding an IP to the Service-Engine and it would not take it, so I assumed I

had it right when it referenced the DSP module. Current version / config is ::

Your config is good and VIF is required as well as enabled for PIM which you already have. Can you confirm the router model and also if this ISR-4k is also acting as the multicast hub ?

goliver · ‎08-28-2018

Sorry, I should have also given some more info on my network setup.

I am using the 4321 as you can see from the config. I also have a workstation on the same subnet as a reporter (192.168.100.113).

When we use the 2{8/9}00s, there is also the Cisco Hoot-N-Holler message broadcast on mcast port+1, so in this case port 27125 that broadcasts constantly. Am I still missing something?

Can you do a code upgrade since I remember a defect on 16.3 release. Upgrade it to the latest and then test. Also ensure that this ISR is not a multicast hub. E&M and multicast hub are not supported if co-located.

but no traffic from the vif for the E&M ports. I raeally am stuck. We opened a TAC case for it -684918674

The customer thought it was PIM, but I believe it is card related or something... Not sure where to go from here..? We are only a development partner with Cisco, so I cannot open TAC cases.

Sorry, I know it has been a while, but I did want to finalize this one out for the records and future searches.

The issue was that the NIM Service-Engine configurations *also* need PIM defined on them. TAC fixed it fairly quickly, but I wanted to share it here as well.

Hi,

Could you please confirm what additional configuration was required?

I can see from the config output on your 08-28-18 post that pim sparse-dense was added to interface Service-Engine0/1/0 and interface Service-Engine0/4/0, but the final post suggests something further was adde.

where else did you need to enable pim?

Any chance you could post the final working config?

Thanks,

Rhys

I no longer have access to that router, but here is the TAC recap. The only thing that needed to be added was PIM on the Service-Engine port of the NIM..

Hello Greg,

Thanks for hopping on our call.

Find the detailed overview of the WebEx below in addition to every item we discussed on the call about the LMR hootie feature on IOS-XE.

As agreed let me know when you have finished testing!

Thanks,

### Problem Description

Customer is configuring LMR/Hootie Feature for ISR4000 for the first time to certify this deployment to sell to customers

### Platform Info

4321 - 16.9.1

### Call Flow

Radio > E&M (voice-port 0/1/0) > 4321 > Gig0/0/1 (192.168.100.254) > Multicast (239.10.10.24)

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> No audio

### Action Taken

Upgraded from 16.3.6 to 16.9.1 as 16.3 was the introduction of the Hootie feature on IOS-XE and 16.7+ have alot of fixes.

Added PIM to the service-engine interface which is the L3 internal interface for the DSP/PVDMs on the NIM Card.

Checked a PCM and can hear SIN traffic with audio so radio and cabling is good for voice port.

Checked the hootie feature with 'show platform hardware qfp active feature sbc hootie group' and I don't see any problems with replication or drops performed by the DSP as there are no drops observed.

Checked 'sh ip igmp member' commands and we see the local endpoint joined to the multicast network properly.

Checking the global drop counters of 'show platform hardware qfp active statistics drop' while I don't see the DSP incrementing failures but I do see the drops for Ipv4mcNoRoute (No IPv4 Multicast Route)

Noticed the VIF was .254 making the internal VIF+1 .255 which is broadcast. So we shut it down and changed to .253 so VIF+1 is .254 then shut/no shut the voice-port to restart the call. Drops still occurred.

'show ip mroute' shows no output so we enabled 'ip multicast-routing distributed' and now we see valid ViF and routes.

At this point testing worked as expected and the Ipv4mcNoRoute drops are gone after clearing 'show platform hardware qfp active statistics drop clear' and doing further testing.

I also used the test command 'test voice port 0/1/0 inject-tone network 1000' sent audio from the DSP towards the IP LAN / Multicast.
