I am working with IR1101 running ir1101-universalk9.17.06.01.SPA.bin with P-LTEAP18-GL LTE module.  I am trying to bring the Cell interface up and have been running into some issues.

The chat-script lte took, but dialer string lte did not.  I swapped out the 255.255.255.255 with 0.0.0.0 in dialer watch-list 1.  Slightly different output from dialer.

Hello,

 

I wonder if your SIM (cellular) gets a physical connection at all.

 

Try the below config (no dialer watch), with an offload to a dialer interface and a dialer persistent...

 

--> chat-script lte "" "AT!CALL" TIMEOUT 20 "OK"
!
controller Cellular 0/1/0
lte sim data-profile 7 attach-profile 7 slot 0
no lte firmware auto-sim
!
interface Cellular0/1/0
ip address negotiated
load-interval 30
dialer in-band
--> dialer pool-member 1
pulse-time 1
ip virtual-reassembly
--> async mode interactive
--> routing dynamic
!
interface Cellular0/1/1
no ip address
shutdown
!
--> interface Dialer1
--> ip address negotiated
--> encapsulation slip
--> dialer pool 1
--> dialer idle-timeout 0
--> dialer string lte
--> dialer persistent
--> dialer-group 1
!
--> ip route 0.0.0.0 0.0.0.0 Dialer 1
!
dialer-list 1 protocol ip permit

A number of the configuration parameters are not available under Cellular interface

 

router(config)#interface Cellular0/1/0
router(config-if)#no dialer in-band
router(config-if)#dialer pool-member 1
%Configure a "dialer in-band", or "dialer pool" first.
router(config-if)#dialer in-band
router(config-if)#dialer pool-member 1
%Remove Legacy DDR Configuration first
router(config-if)#async ?
% Unrecognized command
router(config-if)#routing ?
% Unrecognized command
router(config-if)#routing

I also saw a note pertaining to chat scripts in the configuration guide

 

The following features are not supported on Cisco 4G LTE Advanced on the IR1101, when compared to
Classic IOS:
• TTY support or Line
• Chat script/dialer string
• DM log output to USB flash is not supported

Hello,

 

you don't need the async routing or the script. Try and configure only the below, I would like to see if you get a connection on your cell at all:

!
controller Cellular 0/1/0
lte sim data-profile 7 attach-profile 7 slot 0
no lte firmware auto-sim
!
interface Cellular0/1/0
ip address negotiated
load-interval 30
dialer in-band
--> dialer pool-member 1
pulse-time 1
ip virtual-reassembly
!
interface Cellular0/1/1
no ip address
shutdown
!
--> interface Dialer1
--> ip address negotiated
--> encapsulation slip
--> dialer pool 1
--> dialer idle-timeout 0
--> dialer persistent
--> dialer-group 1
!
--> ip route 0.0.0.0 0.0.0.0 Dialer 1
!
dialer-list 1 protocol ip permit

Hello,

 

what if you delete the profile ?

 

I am not 100% sure what the command is to create/delete a profile, it could be:

 

cellular 0/1/0 lte profile create 1 APN-name none ipv4v6 <-- to create or modify profiles.


cellular 0/1/0 lte profile delete 1 APN-name none ipv4v6

 

or

 

cellular 0 lte profile delete 1 <-- to delete a profile.

 

no lte sim data-profile 7 attach-profile 7 slot 0

 

and create a new one ?

I tried recreating the profile, but did not see any change

Turns out I had the wrong APN name. my original configuration works.  Only other change i did was switch from 3G to 4G.  Thanks for taking a look!
