User Guidelines.
Received frames are assigned to a CoS queue on ingress depending on
configuration such as whether the ingress port is trusted for CoS, DSCP or IP
precedence value and it's mapping onto an internal CoS queue.
IP packets may be remarked using either an in or an out policy map.
Changing the IP precedence value in the ToS value field of an IP packet does
not alter the internal CoS assigned to the packet; it only rewrites the ToS
value in the IP packet header.
Example
The following example displays
console(config)#policy-map p1 in
console(config-policy-map)#class c1
console(config-policy-classmap)#mark ip-precedence 2
console(config-policy-classmap)#
