Configuring Point-to-Multipoint PVC Connections
Note This parameter specifies the weight assigned to the output VC for we ighted round robin scheduling and
is an integer in the range of 1 to 15.This parameter is valid only on systems equipped with the switch
processor feature card. (Catalyst 8540 MSR and Catalyst 8510 MSR and LightStream 1010 with
FC-PFQ). For more information on scheduling, see “Scheduling Output” in the Guide to ATM
Technology.
Note The sched option is only available on OC-48c interfaces. Each OC-48c interface has four OC-12
schedulers. The sched variable is used to select the specific OC-12 scheduler for which the virtual circuit
is assigned for output on an interface and is therefore a number between 1 and 4.
Examples
The following example shows how to configure the root-point PVC on ATM switch router interface
ATM0/0/0, VPI = 50, VCI = 100, to the leaf-point interfaces (see Figure7-4):
Switch(config)# interface atm 0/0/0
Switch(config-if)# atm pvc 50 100 cast-type p2mp-root interface atm 0/1/0 60 200 cast-type
p2mp-leaf
Switch(config-if)# atm pvc 50 100 cast-type p2mp-root interface atm 0/1/1 70 210 cast-type
p2mp-leaf
Switch(config-if)# atm pvc 50 100 cast-type p2mp-root interface atm 0/1/2 80 220 cast-type
p2mp-leaf
Displaying Point-to-Multipoint PVC Configuration
To display the point-to-multipoint PVC configuration, use the following EXEC mode command:
