Chapter 12 Configuring Quality of Service on the ML-Series Card

QoS Configuration Examples

class-map match-any and class-map match-all Commands Example

This section illustrates the difference between the class-mapmatch-anycommand and the class-mapmatch-allcommand. The match-anyand match-alloptions determine how packets are evaluated when multiple match criteria exist. Packets must either meet all of the match criteria (match-all) or one of the match criteria (match-any) in order to be considered a member of the traffic class.

Example 12-6shows a traffic class configured with the class-mapmatch-allcommand.

Example 12-6 Class Map Match All Command Example

ML_Series(config)# class-map match-all cisco1

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# match bridge-group 10

If a packet arrives with a traffic class called cisco1 configured on the interface, the packet is evaluated to determine if it matches the cos 1 and bridge group 10. If both of these match criteria are met, the packet matches traffic class cisco1.

In a traffic class called cisco2, the match criteria are evaluated consecutively until a successful match criterion is located. The packet is first evaluated to the determine whether cos 1 can be used as a match criterion. If cos 1 can be used as a match criterion, the packet is matched to traffic class cisco2. If cos 1 is not a successful match criterion, then bridge-group 10 is evaluated as a match criterion. Each matching criterion is evaluated to see if the packet matches that criterion. When a successful match occurs, the packet is classified as a member of traffic class cisco2. If the packet matches none of the specified criteria, the packet is classified as a member of the traffic class.

Note that the class-mapmatch-allcommand requires that all of the match criteria must be met in order for the packet to be considered a member of the specified traffic class (a logical AND operator). In the example, cos 1 AND bridge group 10 have to be successful match criteria. However, only one match criterion must be met for the packet in the class-mapmatch-anycommand to be classified as a member of the traffic class (a logical OR operator).

Example 12-7shows a traffic class configured with the class-mapmatch-anycommand. In the example, cos 1 OR bridge group 10 OR ip dscp 5 has to be successful match criteria.

Example 12-7 Class Map Match Any Command Example

ML_Series(config)# class-map match-any cisco2

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# match bridge-group 10

ML_Series(config-cmap)# match ip dscp 5

match spr1 Interface Example

In Example 12-8, the SPR interface is specified as a parameter to the match input-interfaceCLI when defining a class-map.

Example 12-8 Class Map SPR Interface Command Example

ML_Series(config)# class-mapspr1-cos1

ML_Series(config-cmap)#match input-interface spr1

ML_Series(config-cmap)# match cos 1

ML_Series(config-cmap)# end

ML_Series# sh class-map spr1-cos1

Class Map match-all spr1-cos1 (id 3)
