IOS XE 16.06.04 and NIM-4G-LTE - Interface not obtaining IP address

Alex Willoughby
Level 1
Level 1

Morning All,

 

Were having an issue with a 4G modem on one of our routers. We never seem to obtain an IP address. We have another modem in a different router configured the same way and that one works without issue (but on a different provider) we have reached out to vodaphone who have confirmed our APN settings are correct. Confirmed there is Data on the SIM and all is working from their point of view, but for some reason we can't see to get it up!

 

We downgraded the IOS to 16.06.04 from 10.10a, to match the working device, have checked everything we can and still no luck, does anyone have any other suggests or debug commands and output to look for that may be useful in diagnosing this?

 

Thanks for any help

Hello,

 

post the full running configuration, not just snippets. What device is this on (which router model) ?

 

 

this is an ISR 4321, added config to original post

Thank you for the suggestions, applied them, no such luck. interface still does not have an IP is down, have reloaded modem again too.

 

Do you know of any useful debug commands for these modems that may give a hint?

 

Thanks

Hello,

 

try:

 

debug modem

debug dialer

 

Also, try and remove the watch group from the interface:

 

interface Cellular0/2/0
description *** Vodaphone sim card ***
ip address negotiated
ip nat outside
dialer in-band
dialer idle-timeout 0
--> no dialer watch-group 1
dialer-group 1
pulse-time 1

nothing much coming from them, I also added debug cellular0/2/0 messages all to the list and it churned out the below, not that I can interpret anything from it, can you see anything in it?

Hello,

 

what is the status of the EN/RSSI/SERVICE LEDs on the router, are they all green ?

Theres no one onsite to take a photo or verify for us, the site is closed at the moment, unfortunately

Hello,

 

I think there needs to be some interesting traffic to initialize the cellular interface. Try and configure a loopback, and the source the IP SLA from that interface:

 

interface Loopback 1

ip address 1.1.1.1 255.255.255.255

!

ip sla 1

icmp-echo 8.8.8.8 source-interface Loopback1

frequency 5
