Yes, WRED can apply to an individual IP Precedence value if you
call it from the MQC. Create a class-map that matches just that
precedence value (or values) that you want, call it from a policy-map,
when apply WRED along with a bandwidth reservation (required). You
config would look something like:
class-map IP_PREC_5
match ip precedence 5
!
policy-map WRED_IP_PREC_5
class IP_PREC_5
bandwidth percent 1
random-detect
!
interface FastEthernet0/0
service-policy output WRED_IP_PREC_5
For the outbound marking on the interface the policy-map is
processed in a top-down fashion (like a route-map or access-list) so
once a match occurs it breaks out of the map. If you want to mark and
then do WRED based on those markings you need to mark inbound on the
incoming interface and then to WRED outbound on the outgoing interface.

Subject: WRED simple question, thank you
Hi, group
I tested WRED on my routers recently, i found servaral questions as
follows:
1. Can WRED be activated based on individual ip precedence value,
that is, only enabling WRED on a specific precdence value while
disabling others?
(As i know, WRED has to be enabled on all precedence value once enabled,
right?)
2. I configured WRED on a 100M fastethernet interface, the default
queueing method is "weighted fair". Do i have to disable it by using
command
"no fair-queue" on that interface?
3. If i set a particular ip precedence on the output of fastethernet
interface, the WRED has happenned before marking or after this marking?
I'am very appreciated every single comment.
