Creating and Entering Subinterfaces
Use the interface command to divide the 1-Port OC-12 ATM line card interface into multiple
subinterfaces to simplify management of the card, create interfaces with different MTU sizes, and create
connections to different networks.
interface atm slot/subslot/port.subinterface type
no interface atm slot/subslot/port.subinterface type

To enter the subinterface at a later time, you do not need to specify the type.
To remove a subinterface and its PVCs, use the no interface command. To change a subinterface type,
you must first remove the subinterface.

slot is 1 to 8
subslot and port are both 0
subinterface is a number from 1 to 4,294,967,295
type is point-to-point or multipoint
Create subinterface number 1 for an 1-Port OC-12 ATM line card in slot 1.
Router(config)# interface atm 1/0/0.1 point-to-point
Router(config-subif)#
Enter an existing subinterface.
Router(config)# interface atm 1/0/0.1
Router(config-subif)#
Use a multipoint subinterface.
If you want multiple PVCs to go to the same network, you must create a multipoint subinterface.
For example:
Router(config)# interface atm 4/0/0.2 multipoint
Router(config-subif)#
After creating the subinterface, you can create PVCs that go to the same network.
a multipoint subinterface on a fully meshed network. Fully meshed indicates that any workstation
can communicate with any other workstation.
