I was reviewing some of the configuration for 10.07. The configuration guide kind of helpped and I put some stuff together. Wanted to get some input.
I am trying to do QoS for our video conferencing software and the vendor advised me that I need to QoS tcp/udp port 41552 and AF41. All our users will be using this so it needs to be deployed across VMs.
class ip QoS_in_ZVideo
10 match udp any any eq 41552
20 match tcp any any eq 41552
policy Policy_ZVideo
10 class ip QoS_in_ZVideo action dscp AF41
qos trust dscp ### Question 2
qos dscp-map 34 local-priority 7 color red name Zvideo_Priority_7
vlan 320 ### Question 1
apply policy Policy_ZVideo routed-in ### Question 1
vlan 330 ### Question 1
apply policy Policy_ZVideo routed-in ### Question 1
interface 1/1/1
qos trust dscp ### Question 2
apply policy Policy_ZVideo routed-in ### Question 3
apply policy Policy_ZVideo in # Question 3
Question 1: Can I just apply it on the VLAN if I don't want to target all physical interfaces? We use different VLANs for different departments. Does it hurt to apply the policy on both the VLAN and interface? If not, which one is recommended?
Question 2: Since I enabled qos trust dscp on the global level, do I need to enable it on the interfaces?
Question 3: There is a apply policy routed-in and apply policy in command. What is the difference between the two?
