Re: Anyone successfully using a Cisco 877 with Qwest?

I have an 877 at a couple of sites using Qwest DSL and Qwest.net as the ISP. This is what I use:

interface ATM0
no ip address
no ip mroute-cache
atm vc-per-vp 64
no atm ilmi-keepalive
pvc 0/32
encapsulation aal5mux ppp dialer
dialer pool-member 1
dsl operating-mode auto
interface Dialer1
description outside interface
ip address negotiated
ip access-group fw_acl in
no ip redirects
no ip unreachables
no ip proxy-arp
ip nat outside
ip ips fw_ips in
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication chap pap callin
ppp chap hostname xxxx
ppp chap password 7 nnnn
ppp pap sent-username xxxx password 7 nnnn
ppp ipcp dns request
ppp ipcp address accept
dialer-list 1 protocol ip permit

I also have a crypto map and service policy on the dialer1 interface but that isn't Qwest specific.

The very first time I setup a router with Qwest I configured both PAP and CHAP since I wasn't sure which one Qwest.net uses. I've left it that way since it doesn't hurt anything.
Turns out Cisco is very consistent. The above config is used on my 827, 837, 877 and the WIC on my 1841 and 2811.

What sort of performance are you seeing?

What does "show dsl int atm0" (or whatever) tell you?

All of my ATM configuration is pretty much at the default. I didn't adjust any of my layer 2 stuff, so I may actually be getting less than my ideal thruput. Of course, I'm pleased as hell that I can get DSL out here in the sticks. Best I could do 3 years ago was 24 Kbps.
