MSLQoS marking IP Prec from one SVI to another SVI on 3560

   I am trying to find a way to set the IP Precedence on traffic leaving one
SVI and received on another. I've tried all kind of things. So many I
can't even remember the details any more. lol. I don't care if it's an
output or an input policy. I just have not been able to find one that works
for traffic on the same SW from one SVI to another.

I do have traffic going all the way through with the IP prec set. So this
is not a matter of the qos getting stripped off. Right now I have a policy
on R1 setting the ip prec to 3. On R4 I have another policy setting the IP
prec to 4. I'm trying to get svi to svi MQC to work here.

1. This didn't work as either an input or output. As an output the sw took
the config, but it didn't show up on the interface.

Policy-map TEST

class class-default

set ip prec 2

interface vlan 234

     service-policy input TEST

OR

interface vlan 234

     service-policy output TEST

2. This didn't work. I got an error stating that the child policy can only
match a physical input interface.

class-map match-all vlan

match input-interface Vlan234

Policy-map CHILD

class vlan

Policy-map PARENT

class class-default

set ip prec 2

service-policy CHILD

interface vlan 234

     service-policy input TEST

3. This didn't work as an output on the physical interface. That is not
permitted.

Policy-map TEST

class class-default

set ip prec 2

*the topology*

rR4---Sw1---Sw2---(vl 234) Sw3/Sw4 (vl 243) ---Sw1--- R3 - that's the
physical topology

R4---Sw1---Sw3/Sw4---R3 is the logical topology

Config on R4

class-map match-all test1

policy-map test1

class test1

class class-default

  set ip precedence 3

Config on Sw1

class-map match-all test1

match access-group 199

policy-map test

class test1

class class-default

  set precedence 4

*Serenity NOW!!*

thanks for the input!
