Cisco 1801 on Magnet Business Broadband

plenderj · 25-12-2008 12:14pm #1

Hi All

This is now starting to wreck the head. We're moving from an existing - and working - cheapo Zyxel DSL router to a Cisco 1801 DSL router. We can get as far as the Cisco unit sync'ing up on the line, but that's about it. When I turn on atm debugging for errors and events, I can see lots of information about the remote end, so I'm pretty sure it's managing to talk to Magnet at least on a low level.

Zyxel used ENET ENCAP. Magnet have told us to use RFC1483 AAL5SNAP on the Cisco. We've tried configuring the router using SDM, SDM Express and CLI. Nothing has worked so far unfortunately.

Below is the running-config and some of the output from bringing up the ATM interfaces. This is about iteration 50 of the config file, ranging from including NAT setups to all manner of other things. Any thoughts/bright ideas?

Additional information; the VPI/VCI are definitely 0/35. When we configure the router using SDM or SDM Express, the following is the running-config with some debugging information below.

I don't see any PPP / CHAP settings there in either config. I assume magnet uses PPPoE and authentication? You will need to get these. Maybe someone can correct me but this is how I would go about it.

Also you have assigned the static address to the ATM interface while also saying the Dialer is getting an assigned address. Without knowing how magnet authenticates its DSL I would say this is incorrect.

I would try get a sample cisco config from Magnet its possible they are doing it differently from the other providers.

Some commands to run:

debug dialer
show dsl int atm0

Post the output of these.

plenderj · 26-12-2008 9:25pm

Thanks for the reply Ronoc

Magnet don't use any authentication, and they use RFC1483/AAL5SNAP. You're also assigned a static IP address. Below is the sample config we received from Magnet. When I'm back in the office tomorrow I'll post the output of those commands. Thanks again!

So it looks like the thing is sync'ing up and connecting to the other end... but nothing seems to happen past that...

Some more updates;

Following a Cisco configuration/troubleshooting guide, when we started to fiddle with PPP, the above changed to 4 packets input, but went no further. Nothing came out on debug ppp neg either.

Any thoughts?

27-12-2008 7:54pm

Just for pure pig iron stick a dialer in magnets suggested config and modify the default route to point to the Dialer.
something like:

interface dialer0
   encapsulation ppp
   ip address IP_HERE SUBNET_HERE
   dialer pool 1
 !
 interface atm 0
   no ip address
 !
 interface atm 0.1 point-to-point
   pvc 0/100
   encapsulation aal5snap 
   protocol ppp dialer
   dialer pool-member 1
!
ip route 0.0.0.0 0.0.0.0 Dialer0

You will need to modify a few line there obviously its just to illustrate.

Do a debug dialer and show ppp and variations of these to get a handle on where its going wrong. Give the router some interesting traffic by (attempting to) ping external hosts from the router and it should try bring up the Dialer or give you some possibly more informative debug output.

plenderj · 28-12-2008 7:24pm

Got it going at last, but unfortunately, only in bridging mode. Our Cisco 1801 is performing NAT/Routing and the ZyXel DSL modem is just doing its ATM/DSL stuff. I'm not happy with the solution because the Cisco router has its own DSL modem, but at least we're up and running on the web now!
