class-map
Create/access a class map. Class maps differentiate traffic so that you can apply separate quality-of-service policies to each
class.
Syntax
class-map {match-all | match-any} class-map-name [cpu-qos] [layer2]
Parameters
match-all Determines how packets are evaluated when multiple match criteria exist. Enter
the keywords match-all to determine that the packets must meet all the match
criteria in order to be a member of the class.
match-any Determines how packets are evaluated when multiple match criteria exist. Enter
the keywords match-any to determine that the packets must meet at least one of
the match criteria in order to be a member of the class.
class-map-name Enter a name of the class for the class map in a character format (32 character
maximum).
cpu-qos Enter the keyword cpu-qos to assign this Class Map to control plane traffic only
(CoPP).
layer2 Enter the keyword layer2 to specify a Layer 2 Class Map. The default is Layer 3.
Defaults Layer 3
