Cisco 881 - Cellular Interface with dialer

[HOT HOT]

Hi Everyone,

I have a cisco router 881 with Cellular interface to backup the Fa4 connection

I was Configured the Interface dialer 1 on my 881 but when I'm configuring the interface cellular and typing the command:

"dialer-group 1" I'm getting the error: "%Remove Dialer Profile Configuration first".

Interface                  IP-Address      OK? Method Status                Protocol

Dialer1                         unassigned      YES manual up                       up

This is the configuration of the interface cellular0:

interface Cellular0
 no ip address
 ip virtual-reassembly in
 zone-member security Untrust
 encapsulation ppp
 dialer in-band
 dialer pool-member 1
 async mode interactive
 no ppp lcp fast-start
end

This is the configuration of the interface dialer 1:

interface Dialer1
 ip address negotiated
 ip nat outside
 ip virtual-reassembly in
 zone-member security Untrust
 encapsulation ppp
 dialer pool 1
 dialer idle-timeout 0
 dialer string xxx
 dialer-group 1
 no ppp lcp fast-start
 ppp chap refuse
 ppp pap sent-username xxx password 7 XXXXXXX
 no cdp enable
end

I was trying to remove the int dialer1 and type the command "dialer-group 1" under the interface cellular0 but I got the same error.

What am I doing wrong?

I have a router that works fine and this is his profile

RTR881G#show cellular 0 profile
Profile password Encryption level: 7

Profile 1 = ACTIVE*
--------
PDP Type = IPv4
PDP address = 192.168.17.43
Access Point Name (APN) = xxx
Authentication = None
Username:
Password: 10

 * - Default profile

Configured default profile for active SIM 1 is profile 1.

What you say about this router?

Hello,

it is possible that your provider doesn't require authentication.

Since you have a working router, what does the chat script look like on that one ?

Is that router connected to the same provider ? Not all chat scripts work the same for all providers. Can you post the working one and the one from your 881 (the one that is not working) ?

[HOT HOT]

chat-script xxx""  "ATDT*99*1#" TIMEOUT 30 "CONNECT"

this is my chat-script

[Georg Pauwen]

Hello,

do a 'debug chat' to see if the chat script is working. You also might want to try this one, it depends on the kind of modem you have in your router:

chat-script xxx "" "AT!SCACT=1,1" TIMEOUT 60 "OK"

Can you post a 'sh version' ?

I posted on the information you need on my first comment

Hello,

try the new chat script and SLIP encapsulation. It would look like this:

chat-script hot "" "AT!SCACT=1,1" TIMEOUT 60 "OK"

interface Cellular0
ip address negotiated
encapsulation slip
dialer in-band
dialer pool-member 1
async mode interactive
!
interface Dialer1
no ip address
ip virtual-reassembly out
encapsulation slip
dialer pool 1
dialer idle-timeout 0
dialer string hot
dialer persistent
dialer-group 1

[HOT HOT]

What doe's it means?

Why did you change the chat script and the encapsulation?

[Georg Pauwen]

It is just a suggestion, maybe it works with that configuration...
