Table 477 Values of matching rules for class
Value	Description
rtp start-port	Define RTP port matching rule. start-port-number is the starting RTP
start-port-number	port number which is valued in the range 2000 to 65535;
end-port	end-port-number is the ending RTP port number which is valued in
end-port-number	the range 2000 to 65535.
qos-local-id	Define qos-local-id matching rule; local-id-valueis the local QoS ID in
local-id-value	the range 1 to 4095.
source-mac	Define source MAC address matching rule.
mac-address

n You can also use the undo if-match[ not ] command in the following syntax to change the ACL used for traffic classification to a new one: undo if-match[ not ] acl [ ipv6 ] { acl-number name acl-name } [ update acl [ ipv6 ] { acl-number name acl-name } ].

Description Use the if-matchcommand to define the matching rule of all packets that match the specified matching rules.

Use the undo if-matchcommand to delete the matching rules.

Use the if-match not command to define the match rule of all packets that do not match the specified matching rules.

Use the undo if-match not command to delete the matching rules.

When defining the rules, take the following into consideration:

1Define ACL matching rule

■If the ACL referenced in a class is not created, the class cannot be applied.

■A class can reference the same ACL by ACL name and ACL number respectively.

2Define destination MAC address matching rule.

■For a class, you can configure multiple commands which cannot be overwritten.

■The match rules of the destination MAC address are only meaningful for interfaces of Ethernet type.

3Define source MAC address matching rule.

■For a class, you can configure multiple commands which cannot be overwritten.

■The match rules of the source MAC address are only meaningful for interfaces of Ethernet type.

4Define matching rule for the class.

When defining both logical AND and logical OR match rules for a class, you may use this command.

For example, to define classA to match rule1 & rule2 rule3 requires to define:

■traffic classifier classB operator and
