How to check trusted traffic

[Sandesh Chavan]

We have SG-500 Switch in our network where Polycom IP phones are connected. We are using basic QOS mode. Below is the configuration for port where phone is connected.

AP-PUNE-ASW05#sh run int gi1/1/2
interface gigabitethernet1/1/2
 spanning-tree bpduguard enable
 qos cos 5
 switchport mode access
 switchport access vlan 53
!
AP-PUNE-ASW05#

Now let me know how to check if traffic from phone on above port is getting assigned with cos 5.

Hi Sandesh,

You can try to check with qos statistics queues if you can see queue 4 statistics is good. If you still not sure than you may need to run wireshark on Linux and mirror traffic from uplink ports and search for dot1q tag. On Windows unfortunately is not easy to see.

This is queue 4 stats i see on port GE1/1/2 & 18 where phones are connected.

I am not able to mirror trunk port on this switch. It shows status not ready.

Gi1/1/49 is trunk port & below is its configuration.

AP-PUNE-ASW05#sh run int g1/1/49
interface gigabitethernet1/1/49
 description TRUNK2CORE
 channel-group 5 mode on
!
AP-PUNE-ASW05#

AP-PUNE-ASW05#sh run int Port-Channel 5
interface Port-channel5
 description TRUNK2CORE
 switchport trunk allowed vlan add 2,52-54,501-502,552
 switchport trunk native vlan 551
!
AP-PUNE-ASW05#

AP-PUNE-ASW05#sh run int g1/1/13
interface gigabitethernet1/1/13
 port monitor GigabitEthernet 1/1/49
 no qos trust
!
AP-PUNE-ASW05#

Please suggest.
