Configuration -WAN Access

10 Low-speed ATM configuration

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 }

A PVC is created and the PVC view appears.

CQ NOTE

In normal cases, the vci values 3 and 4 are reserved for special usage. Nortel recommends users to
not use these two values.

The values of vpi and vci cannot be 0 at the same time.

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

,

aal5muxunstandard

or

aal5nlpid

. By default, the encapsulation type is

aal5snap

.

Step 5

Run:

map ip { ip-address [ mask ]

| default | inarp [ minutes ]

} [ broadcast ]

The command configures the IPoA mapping on the PVC.

When configuring the ip-address, if the specified address is the network segment address or
the multicast address, the key word

broadcast

must be chosen.

InARP is not supported when

aal5mux

,

aal5muxunstandard

and

aal5nlpid

encapsulations

are adopted. To change the encapsulation type for PVC to

aal5mux

,

aal5muxunstandard

or

aal5nlpid

, delete InARP first.

On one ATM interface, configure one PVC with InARP or you can set it as

default

.
