set precedence

After precedence bits are set, other quality of service (QoS) features can then operate on the bit settings.

The network gives priority (or some type of expedited handling) to marked traffic. Typically, you set the

precedence value at the edge of the network (or administrative domain) and data is then queued

according to the precedence. Class-based weighted fair queuing (CBWFQ) can speed up handling for

high-precedence traffic at congestion points. Weighted Tail Drop (WTD) ensures that high-precedence

traffic has lower loss rates than other traffic during times of congestion.

You can verify your settings by entering the show policy-map privileged EXEC command.

This example shows how to give all FTP traffic an IP precedence value of 5:

Switch(config)# policy-map policy_ftp

Switch(config-pmap)# class ftp_class

Switch(config-pmap-c)# set precedence 5

Switch(config-pmap-c)# exit
