I have a problem to get the 3g interface to work, attached it's a configuration and an output for a debug chat.
The 3g interface dont support ppp and it only support slip, with slip I can't configure username and password becauseslip dont support authentication.
my second issue is the chat fails, it's indicated on the debug output attached.I need to know the following:
- how can I configure the username and password for this connection?
- is it possible to enforce ppp encapsulation?
- when to choose to use the virtual-template or a dialer string?
Changed an IOS and the 3G interface worked.
Hi, can you post what was the original IOS and what is the new one? It will be helpful to other people facing the same issue.
Did the IOS upgrade fix both issues?
I am having a similar problem to you with a Vodafone 3G SIM in my Cisco 887VAG+7. I have uppgraded to 15.2(3)T from an earlier release but still can't get the problem resolved.
Was the only thing you did was the upgrade? Was there no other configuration other that what you have attached to the case?
Sorry for this late response, I never had a chance.
Is your problem sorted now?
Thanks for the email. I did get this working in the end. I have shared the important bits of the configuration.
