Okay when you say you pass the tag though lets look an example and let see if i got it
Scenario1
if the packet is coming from the switch to the wireless controller
if it got a voice packet tagged with DSCP(not the default one you use on Wireless controller) does it pass the tag it has whatever it is to the AP?
Scenario2
if the packet goes from the AP to the controller it will tag it with DSCP 56 the controller will keep this tag automatically and pass it to the Switch... now on the switch i can take that DSCP value and maintain it all the way to the ip pbx or all around my network(so it will has priority) even if its using another DSCP value, but the issue with this is that if i got another thing inside the company let say that in the company DSCP 56 was assigned to video... then on the switches they willl have the same priority all over the wired network
What we want is to have the same DSCP value in all the system for my understanding thats is what we should do(im not an expert in QoS neither in Voice) thtas why im asking.
Extra Questions
1-Now if the company is already running another values for Voice and video guess is less work just changing them on the controller, on the WMM option on the SSID right?
2-When the packet is in the air let say i got an IP phone, and im using the same corporate SSID(not needing another SSID for voice like other brands)How does aruba recognize its a voice traffic? with application aware? how does it recognize is a voice traiffc? when im using WMM and the client support it i mean.
3-If the client does not support wmm i got no other option that on the firewall rule to put maybe the ports on a rule and the network its using and give it priority but the problem here is that i cannot use DSCP values on the rule i just can use TOS or 802.1p. How can i manage that? if we are using on our switches DSCP values for priority.
