Hey All,
My long-awaited 4G EHWICs have arrived for my ISRG2 routers. We've gotten SIM cards from Verizon Wireless that have been activated and now i'm trying to make the card work.
I've followed the instructions at this link:
www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/EHWIC-4G-LTESW.html
to do a very basic config, but my interface is still not working correclty.
IOS: 15.1(4)M4
Platform: 2911 SRST/K9
Question 1: Anyone know why my interface shows up as four interfaces on one EHWIC?
yourname#sh ip int brief
Interface IP-Address OK? Method Status Prol
Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down dow
GigabitEthernet0/0 10.10.10.1 YES NVRAM down dow
GigabitEthernet0/1 unassigned YES NVRAM administratively down dow
GigabitEthernet0/2 unassigned YES NVRAM administratively down dow
Cellular0/0/0 unassigned YES NVRAM up up
Cellular0/0/1 unassigned YES unset down dow
Cellular0/0/2 unassigned YES unset down dow
Cellular0/0/3 unassigned YES unset down dow
Loopback0 192.168.1.100 YES NVRAM up up
NVI0 192.168.1.100 YES unset up up

Figured it out. Was missing a space in the chat script.

Hey man, Im running into the same issue. Cant seem to understand whats wrong with mine. My profile is inactive. Do yoiu have a way to fix it?

Finally got one too. We ordered it last november. Quick question for rtjensen4. In the configuration doc it states that you need a username/password for data provisioning. Did you acquire that from verizon?
router#cellular 0/0/0 lte profile create 2 apn.com chap username1 password1 ipv4
Thanks,
Scott

Nope, actually skipped the whole profile part, the default profile worked fine.
05-25-2012 01:09 PM
Thanks! That worked for me too.

Thanks

If you copy and paste the following you will be good to go. You will simply need to add route statements from this point forward
chat-script lte "" "AT!CALL1" TIMEOUT 60 "OK"
interface Cellular0/0/0
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation slip
dialer in-band
dialer string lte
dialer-group 1
async mode interactive
dialer-list 1 protocol ip permit
line 0/0/0
script dialer lte
modem InOut
no exec

In rjensen4's config there wasn't a space after the lte.
So for example the chat scrip had
chat-script lte"" "AT!CALL1" TIMEOUT 60 "OK"
instead of
chat-script lte "" "AT!CALL1" TIMEOUT 60 "OK"
