Priority Configuration
Example
[Sysname] domain system
[Sysname-isp-system] scheme local
[Sysname-isp-system] ip pool 80 10.1.1.2 10.1.1.100
# Configure a VE interface.
[Sysname] interface virtual-ethernet 1
# Enable PPPoE Server on the VT specified on the virtual Ethernet interface.
[Sysname-Virtual-Ethernet1] pppoe-server bind virtual-template 0
[Sysname-Virtual-Ethernet1] mac-address 0022-0022-00C1
[Sysname-Virtual-Ethernet1] quit
# Configure ATM interface 1/0.
[Sysname] interface atm1/0
[Sysname-Atm1/0] pvc 0/32
[Sysname-atm-pvc-Atm1/0-0/32] map bridge virtual-ethernet 1
After the above-mentioned configuration, the link layer is able to work normally,
and the PCs can communicate with the server via the ATM upper layer protocols.
Network requirements
As shown in Figure 12, you need to create PVC 1 and PVC 2 on the same ATM
155 Mbps interface, each assigned 100 Mbps of bandwidth and associated with
the UBR service. Set the transmission priority of PVC 1 to 1 and that of PVC 2 to 3.
Let Router A distribute equal amount of traffic to Router B on two PVCs and
observe the statistics about received/sent/dropped packets.
