ingress-map
The mapping process maps the initial packet's PCP/DSCP value to a designation. The profile map maps from designation to the profile queue. An ingress map also lets you assign a drop-precedence to packets, which may have a value of green
, yellow
or red
. These values are used by WRED queues.
Each ingress interface can have different mappings. For example, you may have customer-facing ports that use one ingress map and some core-facing ports that use a different ingress map.
