Define the Traffic Classes With the class-map Command

Each instance of the class-map command shown in this example links each of the defined traffic classes shown in the prior examples with an identifier by using the set class command. Use the identifiers with the policy-map command, as in the examples in the following sections.

1. Define the traffic class.

   SEFOS# configure terminal 
   SEFOS(config)# class-map 1000 
   SEFOS(config-cls-map)# match access-group ip-access-list 200 
   SEFOS(config-cls-map)# set class 3000 
   SEFOS(config-cls-map)# exit 
   SEFOS(config)# class-map 1001 
   SEFOS(config-cls-map)# match access-group ip-access-list 101 
   SEFOS(config-cls-map)# set class 3001 
   SEFOS(config-cls-map)# exit 
   SEFOS(config)# class-map 1002 
   SEFOS(config-cls-map)# match access-group ip-access-list 102 
   SEFOS(config-cls-map)# set class 3002 
   SEFOS(config-cls-map)# exit 
   SEFOS(config)# class-map 1003 
   SEFOS(config-cls-map)# match access-group mac-access-list 50 
   SEFOS(config-cls-map)# set class 3003 
   SEFOS(config-cls-map)# exit 
   SEFOS(config)# class-map 1004 
   SEFOS(config-cls-map)# match access-group priority-map 500 
   SEFOS(config-cls-map)# set class 3004 
   SEFOS(config-cls-map)# exit 
   SEFOS(config)# exit 

2. Review the information for class-map 1000.

   SEFOS# show class-map 1000

   PriorityMapId        : None 
   CLASS                : 3000 
   PolicyMapId          : None 
   PreColor             : None 
   Status               : Active 

3. Review the information for class-map 1001.

   SEFOS# show class-map 1001

   PolicyMapId         : None 
   PreColor            : None 
   Status              : Active 

4. Review the information for class-map 1002.

   SEFOS# show class-map 1002
   ClassMapId          : 1002 
   L2FilterId          : None 
   L3FilterId          : 102 
   PriorityMapId       : None 
   CLASS               : 3002 
   PolicyMapId         : None 
   PreColor            : None 
   Status              : Active

5. Review the information for class-map 1003.

   SEFOS# show class-map 1003
   QoS Class Map Entries 
   --------------------- 
   ClassMapId          : 1003

   PriorityMapId       : None 
   CLASS               : 3003 
   PolicyMapId         : None 
   PreColor            : None 
   Status              : Active 

6. Review the information for class-map 1004.

   SEFOS# show class-map 1004
   QoS Class Map Entries 
   --------------------- 
   ClassMapId         : 1004 
   L2FilterId         : None 
   L3FilterId         : None 
   PriorityMapId      : 500 
   CLASS              : 3004 
   PolicyMapId        : None 
   PreColor           : None 
   Status             : Active
