How do we know packets using Strict Priority queue for VoIP

Hi,

We have an VoIP network where an IP phone is connected to c2950 switch. I have configured the IP phone to trust dscp values, L3 Sig = 24 and L3 Voice = 46 (Bearing in mind using Cisco default values of VoIP COS=3, COS=5). The IP phone is not Cisco IP phone. It is working but I would like to check packets are send out from the strict priority queue for DSCP values of 46 (cos=5).

Below is the port interface configuration:

interface FastEthernet0/14

description LAN port for IP phone/PC

switchport access vlan 103

switchport voice vlan 115

no ip address

mls qos trust dscp

spanning-tree portfast

!

interface FastEthernet0/44

description LAN port for IP phone

switchport mode trunk

no ip address

mls qos trust dscp

spanning-tree portfast

!

Here is the switchport status of the port

#show interface fa0/14 switchport

Name: Fa0/14

Switchport: Enabled

Administrative Mode: dynamic desirable

Operational Mode: static access

Administrative Trunking Encapsulation: dot1q

Operational Trunking Encapsulation: native

Negotiation of Trunking: On

Access Mode VLAN: 103 (VLAN0103)

Trunking Native Mode VLAN: 1 (default)

Administrative private-vlan host-association: none

Administrative private-vlan mapping: none

Operational private-vlan: none

Trunking VLANs Enabled: ALL

Pruning VLANs Enabled: 2-1001

Protected: false

Voice VLAN: 115 (VLAN0115)

Appliance trust: none

Re: How do we know packets using Strict Priority queue for VoIP

Well,

I did try to enter this command,

it does not have word 'statistics' in the command field.

Any ideas

Thanks
