Usage guidelines
In a traffic class with the logical OR operator, you can configure multiple if match commands for any
of the available match criteria.
When you configure ACL-based match criteria, follow these restrictions and guidelines:
•
If the ACL used as a match criterion does not exist, the traffic class cannot be applied to
hardware.
•
In a traffic class, you can add two if-match statements that use the same ACL as the match
criterion. In one statement, specify the ACL by its name. In the other statement, specify the ACL
by its number.
•
If the ACL contains deny rules, the if-match command is ignored and the matching process
continues.
To configure an input interface match criterion, you must first disable fast forwarding load sharing by
using the undo ip fast-forwarding load-sharing command. By default, fast forwarding load sharing
is enabled.
The source MAC address and destination MAC address match criteria are applicable only to
Ethernet interfaces.
You can use both AND and OR operators to define the match relationships between the criteria for a
class. For example, you can define relationships among three match criteria in traffic class classA
as follows:
traffic classifier classB operator and
if-match criterion 1
if-match criterion 2
traffic classifier classA operator or
if-match criterion 3
if-match classifier classB
When you configure the packet length match criterion, follow these restrictions and guidelines:
•
If you configure only the min min-value option, the match criterion matches packets longer than
min-value.
•
If you configure only the max max-value option, the match criterion matches packets shorter
than max-value.
•
If you configure both min min-value and max max-value (max-value must be greater than
min-value), the match criterion matches packets longer than min-value and shorter than
max-value.
When you configure a match criterion that can have multiple values in one if-match command,
follow these restrictions and guidelines:
•
You can specify up to eight values for any of the following match criteria in one if-match
command:
Description
Matches RTP protocol ports.
The value ranges for the start-port-number and end-port-number
arguments are both 2000 to 65535. This criterion matches RTP packets
with an even UDP destination port number in the specified RTP port
number range.
Matches inner MPLS EXP values.
The exp-value&<1-8> argument is a space-separated list of up to eight
EXP values. The value range for the exp-value argument is 0 to 7.
Matches a source MAC address.
