Atm Pvc Transmission Priority Configuration Example - HPE FlexNetwork MSR series Configuration Manual

Verifying the configuration
Both ADSL Router A and ADSL Router B can ping Router C successfully.

ATM PVC transmission priority configuration example

Network requirements
As shown in
assigned 100 Mbps of bandwidth and is associated with the UBR service. Set the transmission
priority of PVC 1 to 1 and that of PVC 2 to 3.
Configure Router A to distribute equal amount of traffic to Router B and Router C on the two PVCs
and observe the statistics of received/sent/dropped packets.

Router A
ATM2/4/0
202.38.160.1/24
Configuration procedure
1. Configure Router A:
# Configure the ATM interface.
<RouterA> system-view
[RouterA] interface atm 2/4/0
[RouterA-Atm2/4/0] ip address 202.38.160.1 255.255.255.0
# Create two PVCs, and assign them different transmission priorities.
[RouterA-ATM2/4/0] pvc 1 0/33
[RouterA-ATM2/4/0-pvc-1-0/33] map ip 202.38.160.2
[RouterA-ATM2/4/0-pvc-1-0/33] service ubr 100000
[RouterA-ATM2/4/0-pvc-1-0/33] transmit-priority 1
[RouterA-ATM2/4/0-pvc-1-0/33] quit
[RouterA-ATM2/4/0] pvc 2 0/32
[RouterA-ATM2/4/0-pvc-2-0/32] map ip 202.38.160.3
[RouterA-ATM2/4/0-pvc-2-0/32] service ubr 100000
[RouterA-ATM2/4/0-pvc-2-0/32] transmit-priority 3
After two equal amount of traffic exceeding the ATM bandwidth are sent to Router B and Router
C, you can use the display atm pvc-info command on Router B and Router C to view statistics
of each PVC. You can make several tests and observe the average statistics. The output shows
that the PVC with higher priority receives more packets than that with lower priority. The PVC
with the higher priority takes preference in getting bandwidth. Other PVCs, regardless of their
priority values, are treated equally in terms of bandwidth allocation.
