UCS QoS, VoIP applications and upstream switch

[harrygranger]

Hi,

We have followings:

Chassis 5108

FI 6248

FEX 2208

Adapter VIC(1240), 2 vNIC for VMData (VoIP applications), a few others vNIC for mgmt, vmotion etc.

ESXi 5.1

CUCM, Unity, etc

For example, CUCM and Unity marked VoIP media as CoS 5 and signaling as 3.

Will FI overwrite all markings to CoS 5 if VMData vNIC QoS policy is created as platinum with host control FULL (see picture)?

In other words, will the upstream switch see the same QoS markings from VoIP applications?

Thanks,
Harry

If you enable host control and enable COS 5, then yes the FI well overwrite the host assigned QOS.

Hello Harry,

Here is a good link ondesign recommendations on QoS + UC ( VoIP apps ) + UCS

Thanks for the link. It was a very good read.We don't have n1k and will be using vswitch.

I hate to mark non-voip traffics to cs3. So we may have to leave QoS policy out for UC data since we have way more bandwith provision UC apps required.What a tough choice.
