Configure PQ on GigabitEthernet 1/0/2 of Router A, so that the critical packets from the server are
transmitted preferentially when congestion occurs.

# Configure a PQ list to assign the packets from the server to the top queue when congestion occurs.
[RouterA] qos pql 1 protocol ip acl 2001 queue top
# Configure a PQ list to assign the packets from Host A to the bottom queue when congestion
occurs.

# Set the maximum queue size of the top queue to 50 and that of the bottom queue to 100 in the PQ
list.
