■
Assign the VC class to the individual PVC when you create or modify the
PVC.
■
Assign the VC class to the associated ATM major interface or ATM 1483
subinterface before you create the PVC.
Configuring VC Classes
To configure a VC class, you issue the vc-class atm command to create and name
the VC class. The vc-class atm command accesses ATM VC Class Configuration mode,
from which you configure a set of attributes to apply to an ATM data PVC.
Table 8 on page 59 lists the commands that you can use in ATM VC Class
Configuration mode to configure a set of attributes for a data PVC. These commands
are identical to the commands in ATM VC Configuration mode described in
“Configuring Individual ATM PVC Parameters” on page 45. For more information
about the syntax of each command, see the
JUNOSe Command Reference Guide .
Table 8: Commands to Configure VC Class Attributes
oam-pvc cbr
oam retry encapsulation
ubr inarp
vbr-nrt oam ais-rdi
vbr-rt oam cc
For example, the following commands configure two VC classes:
premium-subscriber-class and dsl-subscriber-class. You must issue the
exit command
from ATM VC Class Configuration mode for each VC class configuration to take effect.
! Configure VC class premium-subscriber-class.
host1(config)#
vc-class atm premium-subscriber-class
host1(config-vc-class)# encapsulation aal5autoconfig
host1(config-vc-class)# cbr 200
host1(config-vc-class)# oam-pvc manage 60
host1(config-vc-class)# oam ais-rdi 5
host1(config-vc-class)# exit
! Configure VC class dsl-subscriber-class.
host1(config)#
vc-class atm dsl-subscriber-class
host1(config-vc-class)# encapsulation aal5autoconfig
host1(config-vc-class)# ubr
host1(config-vc-class)# exit
host1(config)#
In premium-subscriber-class:
■
The encapsulation command sets the encapsulation method to aal5autoconfig .
■
The cbr command sets the service category to CBR with a PCR of 200 Kbps.
