mask—Subnet mask of the client entry in dotted-decimal notation (for

example, 255.255.255.0).
A single class map can have multiple match source-address commands. You may
combine multiple match source-address, match access-list, match
destination-address, and match port commands in a class map.
For example, to specify that the class map is to match on source IP address
172.16.20.1 255.255.0.0, enter:
host1/Admin(config)# class-map L4_SOURCE_IP_CLASS
host1/Admin(config-cmap)# match source-address 192.168.10.1
255.255.255.0
To clear the source IP address and subnet mask match criteria from the class map,
enter:
host1/Admin(config-cmap)# no match source-address 192.168.10.1
255.255.255.0
To define a 3-tuple flow of VIP address, protocol, and port as matching criteria
for server load balancing, use the match virtual-address command in class map
configuration mode.You can configure multiple match criteria statements to
define the VIPs for server load balancing. See the Cisco 4700 Series Application
Control Engine Appliance Server Load-Balancing Configuration Guide for
details about configuring the ACE to perform server load balancing.
The syntax of this command is:
[line_number] match virtual-address vip_address {[netmask]
protocol_number | any | {tcp | udp} {any | eq port_number | range port1
port2}}
The keywords, arguments, and options are:

commands. Enter an integer from 2 to 255 as the line number. You can enter
no line_number to delete long match commands instead of entering the entire
line. The line numbers do not dictate a priority or sequence for the match
statements.
• vip_address—VIP server IP address of the ACE, specified in dotted decimal
format (for example, 192.168.1.2).
