Command Mode

User Guidelines
Received frames are assigned to a CoS queue on ingress depending on
configuration items 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 DSCP value in the ToS value 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 how to mark all packets with an IP DSCP
value of "cs4."
console(config-policy-classmap)#mark ip-dscp cs4
mark ip-precedence
Use the mark ip-precedence command in Policy-Class-Map Configuration
mode to mark all packets for the associated traffic stream with the specified
IP precedence value.
This command is not available on the N1500 Series switches.
NOTE:
Syntax
