Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 87 / 774

■
Use to enable Inverse ARP on an ATM PVC that resides on an ATM 1483 NBMA
subinterface and uses the default encapsulation method,
aal5snap .
■
You can optionally specify an Inverse ARP refresh rate, in the range 1–60 minutes;
the default value is 15.
■
You must issue the exit command from ATM VC Configuration mode for the
configuration to take effect.
■
Example
host1(config-subif-atm-vc)# inarp 5
host1(config-subif-atm-vc)# exit
■
Use the no version to restore the default behavior, which disables Inverse ARP
on the router.
■
See inarp.
Configuring ATM VC Classes
As an alternative to configuring individual parameters for ATM data PVCs, you can
access ATM VC Class Configuration mode to configure a class of attributes for an
ATM data PVC. A
VC class is a set of attributes for a virtual circuit (VC) that can include
the service category, encapsulation method, F5 OAM options, and Inverse ARP.
After you configure the VC class, you then apply the attributes in the class as a group
by assigning the VC class to one of the following:
■
An individual PVC
■
All PVCs created on a specified static ATM major interface
■
All PVCs created on a specified static ATM 1483 subinterface
■
A base profile from which bulk-configured VC ranges are created on a dynamic
ATM 1483 subinterface
VC class assignments are valid only for ATM data PVCs created with the pvc
command. Assigning a VC class to a PVC created with the atm pvc command, or to
a control (ILMI) PVC, has no effect. For information about creating a data PVC by
using the
pvc command, see “Creating Data PVCs” on page 47.
NOTE: For information about the total number of VC classes supported on the router,
see JUNOSe Release Notes , Appendix A , System Maximums .
Benefits
Using VC classes to configure and assign attributes to ATM data PVCs provides the
following benefits:
■
VC classes enable you to classify and group ATM PVCs based on the OAM and
traffic requirements of their associated subscribers.
