Configuring Layer 3 and Layer 4 Class Maps

A single class map can have multiple
match destination-address
commands.
You may combine multiple
match destination-address
,
match access-list
,
match source-address
, and
match port
commands in a class map.
For example, to specify that the ACE is to match on destination IP address
172.16.20.1 255.255.0.0, enter:
host1/Admin(config)#
class-map L4_DEST_IP_CLASS
host1/Admin(config-cmap)#
match destination-address 172.16.20.1
255.255.0.0
To clear the destination IP address and subnet mask match criteria from the class
map, enter:
host1/Admin(config-cmap)#
no match destination-address 172.16.20.1
255.255.0.0
Defining TCP/UDP Port Number or Port Range Match Criteria
To specify a TCP or UDP port number or port range as the Layer 3 and Layer 4
network traffic matching criteria, use the
match port
command in class map
configuration mode.
The syntax of this command is:
[
line_number
]
match port
{
tcp
|
udp
} {
any
| {
eq
port_number
} |
range
port1
port2
}
The keywords, arguments, and options are:
•
line_number
—(Optional) Line number to identify individual
match
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.
•
tcp | udp—
Specifies the protocol, TCP or UDP.
•
any
—
Specifies a wildcard value for the TCP or UDP port number. With
any
used in place of either the
eq
or
range
values, packets from any incoming port
match.
