I have a doubt about my config on a IOS 6500 for Voice QOS :

sup 2

interface config :

interface Vlan323

description IPT

bandwidth 100000

service-policy output QosVoice

Policy config :

show policy-map QosVoice

Policy Map QosVoice

class QosVoice

priority percent 10

class QOSdefault

bandwidth percent 89

lass Map match-all QosVoice (id 3)

Match ip dscp 46

DSCP 46 is mapped to COS 5

Physical interface :

interface GigabitEthernet4/2

description Smals LB

logging event link-status

load-interval 30

speed 100

duplex full

udld port

mls qos vlan-based

mls qos trust dscp

What is strange is that no packet are

flagged on the show policy-map.

A show interface Gig4/2 show fifo queueing.

But a show queueing int gig 4/2 shows wrr + pq

Any help would be greatly appreciated.

show policy-map will just display the configuration. "show policy-map interface" will give you QoS statistics. But also be aware, that not every packet may show up though if it is cef switched and the interface is not overloaded. Have a look at

"Understanding Packet Counters in show policy-map interface Output"


Hope this helps!

Thanks Martin,

What I don't get is why the queueing method showed is different with show interface and show queueing ?

Thanks again,
