dscp-map
Description
In a network, each IP packet is assigned a DSCP code that decides its priority. In special
situations, it may be necessary to change this priority.
This change is made using a table in which the DSCP codes are assigned to another queue.
With this command, you configure the assignment table for DSCP codes.
With queues 1 - 6 frames with a lower priority are occasionally processed even if there are
frames with high priority in the queue.
With queues 7 - 8 only frames with a high priority are processed as long as there are frames
with high priority in the queue.
Requirement
You are in the QOS configuration mode.
The command prompt is as follows:
cli(config-qos)#
