Voip and Video Qos

[illcrx]

Hello I have 2 ProCurve 2810-48G switches, current firmware, and we have issues with voip and with video all the time.  I am new to IT and am not quite sure what to do to get past this. 

One issue that I do not think I can get around is we cannot VLAN out of this issue, all of our VOIP clients are browser based. We are using Switch.co an online Chrome based browser service, we only have 2 land lines and they are rarely used. 

I am not sure on the Qos side what I can do to help prioritize data, can it be based on port or another metric? Voip has a dediated port I belive, video however doesnt as far as I know. 

Any ideas?

Check your applications to see what QoS they can have enabled for the packets they generate.

Assuming they can do IP Precedence or DSCP, then on the Access switch you can enable either one of

qos type-of-service ip-precedence

qos type-of-service diff-services

Then make sure your VLAN is a tagged VLAN on the uplink.

Then on the uplink switch (distribution or core) enable 

qos type-of-service diff-services

To make sure your applications' priority is covered, you can do a 

show qos dscp-map

and check out that the ones your applications use are prioritised as 4 (video) or 5 (voice).

Voice should use 46 which is 101110 for DSCP, or just the first 3 bits for ToS, which is 5 (binary 101)

Video should use 34 which is 100010, or for ToS uses 4 (binary 100) 

You should never use a ToS of 6 or 7, (even though HP seems to have 6 configured by default for voice, this will muck you up if you have any non-HP infrastructure which will use the standards-based values, which do not include 6 or 7).
