Primap configuration example
Network requirements
As shown in Figure 6 , Device A is connected through its GigabitEthernet 1/0/1 port to Device C. The
DSCP value of traffic sent out the port is 11. Device B is connected through its GigabitEthernet 1/0/2 port
to Device C. The DSCP value of traffic sent out the port is 13.
Configure priority mapping to satisfy requirements 1 as follows:
• Mark packets from Device A with DSCP 50 and packets from Device B with DSCP 30.
• When Ethernet 1/3 of Device C is congested, Device C schedules the packets according to their
priority prior to priority mapping, and allows Device B to preferentially access Server.
Configure priority mapping to satisfy requirements 2 as follows:
• Mark packets from Device A with DSCP 50 and packets from Device B with DSCP 30.
• When GigabitEthernet 1/0/3 of Device C is congested, Device C schedules the packets according
to their priority after priority mapping, and allows Device A to preferentially access Server.
