Just to make sure that I understand this right:
AF11 = 001011
11 = 001011 ?? Decimal 11?
AF12= 001100
-----------------Logical OR in binary?
xxxxxxx000111 -
On the match of the DSCP bit is it an AND comparison? Stating a 1 is care a 0
is don't care. I guess a test will explain that theory.... :)
Help?
Douglas

Matching values on a single line means logical OR and matching on different
lines is logical AND.
The following two class maps mean the same. Note that, in the first
class-map it's matching any of the dscp values in 3 different lines and in
the second class-map it defines to match all lines, but all the values are
in a single line.
class-map match-any XYZ
match ip dscp af11
match ip dscp 11
match ip dscp af12
class-map match-all XYZ_2
match ip dscp af11 11 af12
Hope this makes sense.

Hi,
is this correct?
Switch(config)# class-map class2
Switch(config-cmap)# match ip dscp 10 11 12
Switch(config-cmap)# end
Switch#
by default class-map is match-all and I think a single packet can not
have dscp of 10,11 or 12.
is not it should be match-any?
This was taken from doc cd
