Dial in backup

Unanswered Question

I have a remote network that I need to install modems for. The network has a few routers and I would like to plug each router to their own external modem via the aux or console port. This is only for management purposes, this is not a backup data link. I have no experience with modems. Can anyone give some advice or point to a white paper that would help me with this.

This link will tell you pretty much everything, I only have a few suggestions -


- use the aux line, not the con line, as con doesn't support hardware flow control on most routers and also is very liberal when it comes to security


- try 'modem autoconfigure discovery' first, it works most of the cases and it will save you from configuring chat scripts where you don't need to


- make sure you have 'modem dialin' or 'modem inout' (if you want callback) in your line configuration


- make sure you configure authentication (i.e., 'login' and 'password' or 'aaa new-model') on the aux line or else you will be refused access.


Hope this helps,

Steju
