Port priority configuration example

Network requirements

As shown in
of traffic from Router B to Router C is 1.
Configure Router C to preferentially process packets from Router A to the server when GigabitEthernet
2/1/2 of Router C is congested.

Configuration procedure

# Assign port priority to GigabitEthernet 2/1/0 and GigabitEthernet 2/1/1. Make sure the priority of
GigabitEthernet 2/1/0 is higher than that of GigabitEthernet 2/1/1, and no trusted packet priority type
is configured on GigabitEthernet 2/1/0 or GigabitEthernet 2/1/1.
