That would work. I'm not sure I'd go so far as to do Flow WRED, but I'd
ask the proctor. You can just as easily tag it and go on.
Class-map telnet
match ip address 142
Access-list 142 permit tcp any any eq telnet
Policy-map mark-telnet
class telnet
set ip dscp 1
Set the service policy inbound to any interfaces to mark traffic as it
arrives.
On the outbound interface, have:
Random-detect dscp 1 20 40 10
And that will take all previously marked traffic and limit it
effectively.
You CAN indeed specify a queue like you have done there and use the same
generic random-detect command. So multiple ways to skin the cat!
Hope this helps,
Scott

So this means using class to match the traffic of interest and
applying the WRED parameters won't work?
Ex.
Class-map WRED_TELNET
match ip address 142
access-list 142 permit tcp any any eq telnet
Policy-map DROP_TELNET
class WRED_TELNET
bandwidth 2048
random-detect flow
random-detect flow average-depth-factor 20
random-detect flow count 40
and applying service policy DROP_TELNET to the interface??? or I am off
base here? What is the best way of applying WRED to a specific traffic
type?

There are a couple different ways to do it, but the bottom line is
that
you classify your traffic before deciding how to handle it.
For example, set up a CBWFQ and one queue deals with telnet traffic.
Within this queue you use random-detect with the parameters you have
mentioned.
Another way is to mark the traffic on ingress perhaps even with
policy
routing. Set a DSCP tag onto the traffic. Then use random-detect
dscp
with the values you have listed on the egress point.
AFAIK, there isn't an ACL parameter on any of the random-detect
command
lines.
Enjoy!

Subject: WRED
I am trying to configure WRED. I can configure WRED based on
precedence
but I am having difficulty finding in CCO how to configure based on
different types of ip traffic.
For example.
Configure WRED so that telnet traffic will be randomly dropped if
queue
lenght is over 20 and completely droped if over 40
I am having proble with specify telnet traffic in the configuration.
Please help. .
