Advanced Configuration
111
The port-based mode is configured on port 1. The default priority of port 1 is 6. Packets from
port 1 are mapped to queue 3. The 802.1p priority carried by packets from port 2 is 2, which
is mapped to queue 1. The 802.1p priority carried by packets from port 3 is 4, which is
mapped to queue 2. The DSCP priority carried by packets from port 4 is 6, which is mapped
to queue 3. Port 5 adopts the WRR scheduling mode.
Configuration steps:
1. Select WRR for QoS mode and keep the default values for the WRR queue weight ratio,
as shown in Figure 99 and Figure 100.
2. Configure highest priority-queue mapping on port 1, 802.1p on port 2 and port 3, and DIFF
on port 4, as shown in Figure 101.
3. Configure 802.1p priority 6, 2, and 4 to map to queue 3, 1, and 2 respectively, as shown in
Figure 102.
4. Configure DSCP priority 6 to map to queue 3, as shown in Figure 103.
Figure 110 QoS Configuration Example
Packets received through port 1 and port 4 are put into queue 3; packets received through
port 2 are put into queue 1; packets received through port 3 are put into queue 2. According
to the mapping between queues and weights, the weight of queue 1 is 2, the weight of queue
2 is 4, and the weight of queue 3 is 8. As a result, the packets in queue 1 enjoy 2/(2+4+8)
bandwidth, those in queue 2 enjoy 4/(2+4+8) bandwidth, and those in queue 3 enjoy
8/(2+4+8) bandwidth. Packets received through port 1 and port 4 are put into queue 3 and
forwarded according to the FIFO mechanism. The total bandwidth ratio of port 1 and port 4 is
8/(2+4+8).
