Expressions We will now have a look at this expression. Therefore go to the expression page and
select the Service tab:
Expert mode -> IP Router -> Expressions
This will show you a list of service expressions defined, if a default configuration is
used.
When we click on the + next to the DiffServ expression name we can see the
definitions used for this expression.
Here we can see that the expression DiffServ is used for packets:
 with the dscp set to a value different from 0. (dscp=!0)
The
!
sign means that the value is allowed to be
anything but
0.
These are all parameters needed to enable classification for packets with
DSCP set. The actual Quality of service is defined later on.
