2 Checking the configuration
11.3.2 Configuring IPoA mapping on a PVC
Do as follows on the routers:
Step 1 Run:
system-view
The system view appears.
Step 2 Run:
interface atm interface-number[.subinterface ]
The ATM interface or the sub-interface view appears.
Step 3 Run:
pvc { pvc-name vpi/vci | vpi/vci }
The command creates a PVC and the PVC view appears.
Step 4 Run:
encapsulation aal5-encap
The command configures the encapsulation type of the PVC as AAL5.
The AAL5 encapsulation type for PVC can be aal5snap , aal5mux .
By default, it is aal5snap .
InARP is not supported when you adopt aal5mux . To change the encapsulation type for PVC
to aal5mux , first delete the InARP.

NOTE
• When the encapsulation command is run on the high-speed ATM interface card, the four types of
AAL5 encapsulation display in the prompt information: aal5snap, aal5mux, aal5muxunstandard, and
aal5nlpid. The PVC of the low-speed ATM interface card supports these four types of AAL5
encapsulation. The PVC of the high-speed ATM interface, however, supports only two types of
encapsulation: aal5snap and aal5mux.
• When you configure the AAL5 encapsulation type of the PVC of the high-speed ATM interface as
aal5muxunstandard and aal5nlpid, the system prompts the alarm information for the error
configuration.
Step 5 Run:
map ip { ip-address [ mask ] | inarp [ minutes ] } [ broadcast ]
The command configures the IPoA mapping on the PVC.
When configuring the ip-address, if the specified is the network segment address or the
multicast address, you must choose the key word broadcast .
