Configuring Marking Using Table Maps - Cisco Nexus 7000 Series Configuration Manual

Configuring Marking Using Table Maps

Note You can use only one of the system-defined table maps in this procedure. For information on the system-defined
table maps, see "Using Modular QoS CLI."
Configuring Marking Using Table Maps
You can use the system-defined table maps to perform marking in the set and police policy map class
commands.
Note
For the list of system-defined table maps, see "Using Modular QoS CLI."
A source field and destination field are specified in the command that maps to the source and destination
values supplied in the referenced table map. The QoS fields that can be used in these commands are listed in
the table below.

By using the system-defined table maps, you cannot change unlike values, but you can only change one value
to another when it is the same variable. You can use the markdown system-defined table maps for the exceed
or violate action of the police command by using the same syntax as the set command.
Note The internal label QoS group is not supported through table maps.
Note Marking down in the police command requires the use of a table map.
For information on the police command, see "Configuring Policing."
