Show policy-map interface fa0/24 will show you stats specific to the policy
map attached to that interface.

Subject: 3550 + Match VLAN - QOS

Hello ,

I am trying to match a VLAN and assign the ip precedence value instead of
using matching ACL to assign the ip precedence.

Match Vlan XX . Assign ip precedence 1

I tried the following first.

!
mls qos
!
class-map VLAN15
match vlan 15
!
Policy-map PREC1_VLAN15
class VLAN15
set ip precedence 1
!
int Fa0/24
service-policy input PREC1_VLAN15
!
service-policy input PREC1_VLAN15
QoS: match class-map must follow match vlan in class-map VLAN.

***************************

Then I tried the following by adding the match class-map class-default under
class-map VLAN15 .

mls qos
!
class-map VLAN15
match vlan 15
match class-map class-default
!
Policy-map PREC1_VLAN15
class VLAN15
set ip precedence 1
!
int Fa0/24
service-policy input PREC1_VLAN15
!

Question .

1. Whatever am I doing is correct ?
2. How to verify is it working ? show mls qos int Fa0/24 statistics
doesn't show anything related with my configuration.

Thanks,
Rajakumar
