1 Configuring IPoA mapping on a PVC
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.
z
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.
z
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.
