Hi
I have edge switches connected to core switch using trunk. We have attached cisco Ip phone to end switches , we are going to deploy QOS . As below we implemented auto qos voip cisco-phone under cisco access switches interfaces and under trunk we did "auto qos voip trust ". I have two questions as below:-
interface GigabitEthernet0/4 //trunk interface to core switch/
switchport trunk allowed vlan 30,106,107
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
queue-set 2
priority-queue out
udld port aggressive
mls qos trust cos
auto qos voip trust
interface FastEthernet0/38 //access switch interface connect to IP phone//
switchport access vlan 30
switchport mode access
switchport voice vlan 107
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
service-policy input AutoQoS-Police-CiscoPhone
Q1- "service-policy output AutoQoS-Police-CiscoPhone" should be applied under the trunk between access and core switches?.
Q2- From Core side ,should i apply "auto qos voip trust" under the trunk which connected to the edge switch?.
Thanks
