I would submit that the threshold for RED is exactly what you're looking
for here. If you set a threshold at 60%, at that point RED kicks in and
begins to drop packets. Before that time, packets flow normally.

Hmmm, I am not sure if you can control "when" RED is in effect. Other
than based on dscp or precedence. Maybe someone else has some ideas on
this one.

yep,
thats what i want , if traffic exceed 60 % enable random detect on the
interface

That is an interesting lab question....it appears the first

would provide a minimum of 60 percent of the link for all
traffic and
also do random detect on the same traffic, since they are both
part of
the same class. The second one is similar, but shaping to 60%
and also
doing random detect on that traffic. However, the way I read
your
question is...to only do random detect when the threshold of 60%
is
exceeded. Is this what you are looking to do?

dear all,
I have a question, if said all traffic on an interface will use
60 % and
you
must enable random detection if traffic pass this limit,
I have 2 things in minds but i dont know who will be the correct
answer.
1- by using the bandwidth command
policy-map xx
class all-traffic
bandwidth percent 60
random detect
!
where class all-traffic will match all the traffic
but as far as I know the bandwidth command will not reserve the
60 %
untill
there is a congetion on the physical interface itself, and
random detect
will not work there is a main interface congestion and the
traffic will
exceed 60 % Am i right about that ????
2- by using the shaping command and i think this will be the
right
answer:
policy-map xx
class all-traffic
shape average percent 60
random detect
!
I think this will be the solution?
any comment or any other solutions about that?
