C1111-8PLTE / LTE Troubles

[solarwinds123]

I'll keep this brief as possible; I'm having trouble bring up my LTE / Cell0/2/0 connection on my C1111-8PLTE.

I can get the connection up with nearly no action by me on a fresh start (no startup-config). After adding a static route, I can pass traffic in/out the LTE connection. Once I reboot, Cell0/2/0 connection does not come back up with a valid IP.

 Any thoughts on this? What am I doing wrong?

Hello,

post the full non working running configuration, as it is difficult to see what you actually have configured.

The line

access-list 1 permit ip any

alone would not allow external access.

Make sure the config look something like below:

Thank you, this gave me what I needed to get this working.

This is what I was missing:

Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)#dialer-list 1 protocol ip permit
Router(config)#interface Cellular0/2/0
Router(config-if)# dialer in-band
Router(config-if)# dialer-group 1
Router(config-if)# pulse-time 1
Router(config-if)#end

*Oct 25 17:15:00.994: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0/2/0, changed state to up

[Georg Pauwen]

Hello,

can you post the working running configuration for reference ?

[solarwinds123]

Absolutely. Keep in mind this config is lacking a LAN port and NAT statements... It's ultra basic and allowing for only access out to the internet for testing:

Router#show run
