2 Define the traffic from PC1.
# Create a number-based basic ACL 2000 and enter it.
[SW8800] acl number 2000
# Define ACL rule for the traffic from PC1.
[3Com-acl-basic-2000] rule 0 permit source 1.0.0.1 0 time-range 3Com
3 Modify the next hop for the packets from PC1.
# Define the next hop for the packets from PC1 as 2.0.0.1.

Queue Scheduling
Configuration Example
Network requirements
Modify the correspondence between 802.1p priority levels and local priority levels
to change the mapping between 802.1p priority levels and queues. That is, put
packets into outbound queues according to the new mapping. Use WRR
algorithm for the queues 0 to 5 at the port GE7/1/1. Set the queues 0, 1 and 2
into WRR queue 1, with weight respectively as 20, 20 and 30; set the queues 3, 4
and 5 into WRR queue 2, with weight respectively as 20, 20 and 40. The queues 6
and 7 use SP algorithm. See Queue Scheduling for the default mapping.
