I'm having issues with a 1921 and a new 4G card.
Below is the running config, show cellular and debug. The SP is EE in the UK, the APN is supposed to be everywhere, eesecure is the user and the password is also set (although not shown). The SP has confirmed the SIM is fine and the profile is correct. Apart from that they are not willing to help.
Can't see what is wrong here, any ideas? Anything else I can check?
Thanks
Chris

It's a bug
basically you need to reset the modem after a reboot.
so I entered
test cellular 0 modem-power-cycle
After this the unit will connect until the unit is rebooted/powercycled.

This line of your output caught my attention
*Nov 1 10:47:18.059: Ce0/0/0 DDR: Dialing cause ip (s=192.168.1.1, d=8.8.8.8)
I am not clear where the source address of 192.168.1.1 came from. Is that the address learned by the cellular? If not what is it?

It's the IP of loopback 0.
I'm not expecting that to ping (it's a RFC 1918 address) but the cellular interface should come up.
At this point the cellular interface has not learned an IP.

So something is being triggered it is just the script does not get a response so the interface does not come out of spoofing.
Is teher any way to decode what the cellular debugs actually mean or how they should look?

Thanks for the additional information. If the source address of your ping will be 192.168.1.1 then I suggest that you modify your configuration of address translation and add a permit for 192.168.1.0. It has been my experience with 4G that providers reject traffic with that kind of source address and expect the source address to be in their address range.
Change your address translation, try the ping again, and let us know if the behavior changes.

I did try but it makes no difference. The Cellular interface does not, at this point, have an IP address so NAT is not performed (there is no IP to NAT to).
The failure is at Layer 2 in that the modem command does not get a response to activate the interface even though the profile is active (hence layer 1 is complete). The Provider never sees the IP packet as it is never sent.
This maybe one for TAC.

Thank you for the update and the explanation of the problem. That is very helpful information. Perhaps at this point you might mark the question as answered so that other readers would know that a solution has been found?

You can't mark your own replies as answers I'm afraid.
11-08-2013 08:09 AM
I guess that is right. In that case I will Endorse your response and it will be flagged in a somewhat similar way (not quite the same impact as you saying it is solved but at least it may get it a bit more attention as people read the forum).
