Hi, all

I'm configuring WRED.

But There are some confusing issues.

1) Telnet randomly dropped if queue is over 10 and completely dropped if
over 30
2) FTP randomly dropped if queue is over 10 and completely dropped if
over 25
3) Rest of the traffic randomly dropped if queue is over 30 and
completely
dropped if over 60
4) Drop probability is 1 in 20 packet

<my config>

access-list 101 permit tcp any any eq telnet
access-list 102 permit tcp any any eq ftp-data
access-list 102 permit tcp any any eq ftp

route-map kms permit 10
 match ip address 101
 set ip precedence priority
!
route-map kms permit 20
 match ip address 102
 set ip precedence immediate
!

route-map kms permit 30
!

interface Ethernet0 ----------> ingress traffic interface
 ip policy route-map kms
!
interface Serial0
 random-detect
 random-detect precedence 0 30 60 20
 random-detect precedence 1 10 30 20
 random-detect precedence 2 10 25 20
!
!

------------------------------------------------------

My config is right ??

<My Question>

1. Is that right that "route-map" is used in Ehternet0 (ingress
interface) ?

Engress is right? I guess "Ingress" is right...

2. Is it possible to use "policy-map" instead of "route-map"???

If it is possible, plz give me examples...

3. "precedence 0 30 60 20" means any traffic is......30 60 20..

By default, All of traffic are "precedence is 0". Right??

thanks..
