Hello,
I think this works as following:
Split the DSL controller in 4:
2811(config)# controller shdsl 0/1/0
2811(config-controller)# dsl-group 0 pairs 0
2811(config)# controller shdsl 0/1/0
2811(config-controller)# dsl-group 1 pairs 1
2811(config)# controller shdsl 0/1/0
2811(config-controller)# dsl-group 2 pairs 2
2811(config)# controller shdsl 0/1/0
2811(config-controller)# dsl-group 3 pairs 3
Then use the procedure below to assign IP addressing and other config to the groups:
1. dsl-group
2. interface atm <slot>/<HWIC subslot>/<dsl-group>
3. ip-address IP-address
4. atm-ilmi-keepalive seconds
5. pvc [name] vpi/vci
6. protocol ip IP-address
7. vbr-rt peak-rate average-rate burst
The document linked below lists this and other options:
