Router(config)# interface atm 2/0/0
Router(config-if)# atm framing g751plcp

Creating and Entering Subinterfaces

Use the interface command to segment an E3 or T3 ATM main interface into multiple subinterfaces to
simplify line card management, to create interfaces with different MTU sizes, and to create connections
to different networks.
interface atm slot/subslot/port.subinterface type
no interface atm slot/subslot/port.subinterface type

slot is 1 to 5 for a Cisco 10005 router.
slot is 1 to 8 for a Cisco 10008 router.
subslot is always 0 for a full-height line card.
port is 0 to 3.
subinterface is a value from 1 to 4294967295.
type is always point-to-point or multipoint.
Create subinterface number 1 at port 3 for 8-Port E3/DS3 ATM line card in slot 1.
Router(config)# interface atm 1/0/3.1 point-to-point
Router(config-subif)#
Enter an existing subinterface.
Router(config)# interface atm 1/0/3.1
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 4/0/2.2 multipoint
Router(config-subif)#
