Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Руководство по настройке

Страница: 101 / 774

In the following example, assume that RADIUS has been configured to apply a service
category of CBR with a PCR of 400 Kbps to the PVC. Initially, the PVC uses the service
category configured in my-premium-class, CBR with a PCR of 200 Kbps. However,
when the subscriber logs in through RADIUS, the router applies the RADIUS-configured
service category, CBR with a PCR of 400 Kbps.
While the subscriber is still logged in, my-premium-class is modified to change the
service category to CBR with a PCR of 600 Kbps. Because this VC class modification
results in the most recent, explicitly specified value for the service category, the
router now uses CBR with a PCR of 600 Kbps as the service category for the PVC
instead of the service category configured through RADIUS.
host1(config)# interface atm 2/0.200
host1(config-subif)# pvc 200 0/200
host1(config-subif-vc)# class-vc my-premium-class
host1(config-subif-vc)# exit
! Subscriber logs in through RADIUS, which applies service category of CBR
! with a PCR of 400 Kbps to PVC.
host1(config)#
vc-class atm my-premium-class
host1(config-vc-class)# cbr 600
host1(config-vc-class)# exit
! Router now applies service category of CBR with a PCR of 600 Kbps to PVC.
Configuring Dynamic ATM 1483 Subinterfaces
As an alternative to the static ATM interface configurations described in this chapter,
you can also configure dynamic ATM 1483 subinterfaces over static ATM AAL5
interfaces over ATM. Dynamic ATM 1483 subinterfaces can perform autodetection
and dynamic creation of the following upper-layer encapsulation types:
■
Bridged Ethernet
■
IP
■
PPP
■
PPPoE
For details, see “Configuring ATM 1483 Dynamic Subinterfaces” on page 628 in
“Configuring Dynamic Interfaces Using Bulk Configuration” on page 623.
Monitoring ATM
This section explains how to set a statistics baseline, display bit rate and packet rate
statistics for ATM virtual circuits (VCs), and use the
show commands to view your
ATM configuration and monitor ATM VCs and VPs.
NOTE: The E120 and E320 routers output for monitor and show commands is
identical to output from other E Series routers, except that the E120 and E320 routers
output also includes information about the adapter identifier in the interface specifier
(
slot / adapter / port ).
