Priority Marking

The priority marking function is to reassign priority for the traffic matching an ACL referenced for traffic
classification.
If 802.1p priority marking is configured, the traffic will be mapped to the local precedence
corresponding to the re-marked 802.1p priority and assigned to the output queue corresponding to
the local precedence.
If local precedence marking is configured, the traffic will be assigned to the output queue
corresponding to the re-marked local precedence.
If IP precedence or DSCP marking is configured, the traffic will be marked with new IP precedence
or DSCP precedence.

Traffic Policing and Traffic Shaping

The network will be made more congested by plenty of continuous burst packets if the traffic of each
user is not limited. The traffic of each user must be limited in order to make better use of the limited
