Version Description
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
The unit of bandwidth percentage is 1%. A bandwidth percentage of 0 is allowed and disables the
scheduling of that class. If the sum of the bandwidth percentages given to all eight classes exceeds 100%,
the bandwidth percentage automatically scales down to 100%.

Commands
qos-policy-output — creates a QoS output policy.
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 [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).
layer2 Enter the keyword layer2 to specify a Layer 2 Class Map. The default is Layer 3.
