Parameter
ip-dscp value: DSCP value in the range of 0 to 63.
Description
Using the if-match dscp command, you can define DSCP match rule. Using the
undo if-match dscp command, you can delete DSCP match rule.
You can configure this command for a class for several times. When a command is
configured, the ip-dscp-value will be sorted in the ascending order automatically. Only
when the specified DSCP values are identical with those in the rule (sequence may
be different), can the command be deleted.
Up to 8 DSCP values can be configured by a command. If several DSCPs are
configured with the same value, they will considered as one by default. The relation
between different DSCP values is “OR”.
For the related command, see qos class.
Example
Define the match rule of class1 as matching the packets with the DSCP value as 1, 6
or 9.
