atm pvc
■
Use to configure a PVC on an ATM interface.
■
Specify one of the following encapsulation types:
■
aal5snap —Specifies an LLC encapsulated circuit; LLC/SNAP header precedes
the protocol datagram.
■
aal5mux ip —Specifies a VC-based multiplexed circuit. This option is used
for IP only.
■
aal5autoconfig —Enables autodetection of the 1483 encapsulation (LLC/SNAP
or VC multiplexed) for dynamic interfaces. See “Configuring Dynamic
Interfaces” on page 515, for more explanation.
■
ilmi —Defines the PVC for ILMI keepalive messages. You can set this option
only on major interfaces. After the PVC is set up for ILMI, use “atm
ilmi-keepalive” on page 30 to cause the router to generate ILMI keepalive
messages on the interface.
■
You can optionally set the peak , average , and burst sizes. To use VBR-RT or
VBR-NRT as the service type, you must specify each of these options.
■
The default service type is UBR. To set a different service type, specify one of
the following keywords:
■
rt —Selects VBR-RT as the service type. You can select rt only if you set the
peak , average , and burst parameters.
■
cbr —Selects CBR as the service type. You must set the CBR rate in Kbps.
