Policy routing can't be applied inbound direction??
I didn't know that...
If it is right, this config is possible??
Which command is processes first?
and
How can I test (precedence or WRED)??
Any debug command?
<Another Config>
class-map match-all telnet
match protocol telnet
class-map match-all ftp
match protocol ftp
!
!
policy-map kms
class telnet
set ip precedence 1
bandwidth percent 40
random-detect
random-detect precedence 1 10 30 20
class ftp
set ip precedence 2
bandwidth percent 40
random-detect
random-detect precedence 2 10 25 20
class class-default
set ip precedence 0
bandwidth percent 20
random-detect
random-detect precedence 0 30 60 20
interface Serial0/0 -----> Engress traffic interface
service-policy output kms

Policy routing is applied in an outbound (egress) direction. Packets
coming
into your Ethernet interface will not have there precedence changed.
