Example 2—This example generates segment loopback cells for VPI=0 and VCI=105
on ATM interface 2/0. The destination is set to 0xFFFFFFFF, the count value is 3 OAM
loopback cells, and the timeout value is 1 second.

You configure an ATM NBMA 1483 subinterface in a manner similar to configuring a
standard ATM 1483 subinterface. When you specify a subinterface, however, you must
select the multipoint option if you plan to add multiple circuits to form an NBMA interface.
If you do not select multipoint, the subinterface defaults to point-to-point, and only a
single circuit can be affiliated with that subinterface.
You can configure one or more PVCs and associate them with the subinterface you create.
Also, you can enable InARP and identify a refresh rate on each specific circuit. For each
NMBA interface, either InARP must be enabled, or a static map entry must be provided
for each circuit owned by the interface; otherwise, transmitting over that circuit is
impossible.
NOTE: NBMA interfaces support only the aal5snap encapsulation.
To configure an NBMA interface:
Configure a physical interface.
1.
host1(config)#interface atm 2/0
Configure an ATM 1483 subinterface.
2.
host1(config-if)#interface atm 2/0.2 multipoint
Configure PVCs by specifying the VCD, VPI, VCI, and encapsulation type.
3.
host1(config-subif)#atm pvc 1 1 1 aal5snap inarp 10
host1(config-subif)#atm pvc 2 2 2 aal5snap
(Optional) Specify InARP and a refresh rate (also optional).
4.
host1(config-subif)#atm pvc 3 3 3 aal5snap inarp 5
host1(config-subif)#atm pvc 4 4 4 aal5snap inarp
Assign an IP address and subnet mask to the PVC.
