How to configure AIM-ATM in 2811?

Unanswered Question
Mar 15th, 2007


I have a 2M ATM circuit on RJ45. Is there any special requirement for a 2811 with AIM-ATM module to use the ATM circuit? Any sample config?

I have this problem too.

Lets say you have AIM card in slot 1 and VWIC card installed in WIC2 slot

network-clock-participate wic 2

network-clock-participate aim 1

network-clock-select 1 E1 0/2/0

controller E1 0/2/0

mode atm aim 1

interface ATM0/IMA3

no ip address

no atm ilmi-keepalive

interface ATM0/IMA3.77 point-to-point

pvc 1/77

ubr 3840

oam-pvc manage 0

encapsulation aal5snap

interface ATM0/2/0

no ip address

no scrambling-payload

ima-group 3

no atm ilmi-keepalive

Hope this helps.

Unfortunately I do not have any VWIC card installed. Can I used the FastEther since the 2M ATM that the ISP provide is on RJ45?

Unfortunately you cannot get away by terminating at FastE, I know ISP provides RJ45 but that must be getting terminated on VWIC on 2811. RJ45 do not understand ATM format hence you would need a vwic at a minimum in order to turn up the ckt.
