[c-nsp] Cisco 1720 and ip cef

[Nigel]

Hi All,
 
I am running into some trouble regarding the cisco 1720 and ip cef load
balancing.
 
The router has 2 adsl wics in it. Each dsl connection is 1.5M/256.
 
The problem is that on the outbound path the traffic is only ever going out
1 specific wic. I have tried forcing cef to per packet in order to push
traffic out both interfaces, but this still results in traffic only going
out the 1 interface still. If I shutdown the interface that is passing
outbound traffic the router drops of the network completely.
 
The inbound traffic comes down both wics. So far the ios has been upgraded
to 12.3(10) and the wic has been swapped out. Neither has made a difference.
 
It leaves the actual wic slot on the 1720 or the possibility that the 1720
just can't deal with load balancing.
 
Here are the outputs from the interfaces:
 
Router#sho int atm0 | inc rate
  Queueing strategy: Per VC Queueing
  5 minute input rate 112000 bits/sec, 38 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
 
 
Router#sho int atm1 | inc rate
  Queueing strategy: Per VC Queueing
  5 minute input rate 110000 bits/sec, 37 packets/sec
  5 minute output rate 32000 bits/sec, 98 packets/sec

 
Any ideas at all?
 
Thanks in advanced.

Regards,

Nigel
