Configuring Layer 3 and Layer 4 Class Maps Chapter 4 Configuring Class Maps and Policy Maps When you create a class map, you will enter class map configuration mode. To classify network traffic passing through the ACE, include one or more of the following commands to configure the match criteria for the class map: • description-See the "Defining a Class Map Description" section • match access-list-See the"Defining Access-List Match Criteria" section • match any-See the "Defining Match Any Criteria" • match destination-address-See the "Defining Destination IP Address and Subnet Mask Match Criteria" section • match port -See the "Defining TCP/UDP Port Number or Port Range Match Criteria" section • match source-address -See the "Defining the Source IP Address and Subnet Mask Match Criteria" section • match virtual-address-See the "Defining the VIP Address Match Criteria" section Following these guidelines when creating a class map to define a Layer 3 and Layer 4 match classification: • You can include only one match any command within a class map and you cannot combine the match any command with other types of match commands in a class map since the other match criteria will be ignored. • You may combine multiple match access-list, match source-address, match destination-address, and match port commands in a class map. • You can include multiple match virtual-address commands within a class map. The match virtual-address command, however, cannot be combined with the other types of match commands in a class map. This command is intended to define a 3-tuple flow of VIP address, protocol, and port as matching criteria for server load balancing. 4-26 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
