We have a pair of Microsoft Surface Hubs we're testing out between our main office and our remote office in another part of the country. The offices are connected by a 10mbit MPLS circuit.
Currently we use Skype for Business internally and have assigned QoS and port ranges to the clients via a GPO and this seems to be working fine. We have a QoS policy in our switches (QP6) for any traffic with set DSCP values:
configure diffserv examination code-point 24 qosprofile QP6
configure diffserv examination code-point 34 qosprofile QP6 configure diffserv examination code-point 46 qosprofile QP6
Problem is, the surface hub doesn't behave like a normal SFB client and its not reading the GPO objects so its sending all of its traffic untagged, which is causing issues when the link gets busy.
I started reading about using diffserv replacement, but got lost to be honest.
Rocket1.30 # sh diffserv replacement QOSProfile->CodePoint mapping: QP1 -> 00 QP6 -> 40 QP8 -> 56 What I'd like to do is all traffic coming from host 10.22.0.125(plugged into port 4) be tagged with DSCP 46 until I can work with Microsoft to get this box to apply the proper GPO to the client.
I understand that I need to enable diffserv replacement port 4 and use an ACL to catch all traffic from 10.22.0.125 and use replace-dscp like this:
entry surfacehub { if { source-address 10.22.0.125/32 } then { Qosprofile qp6; replace-dscp; }But if I'm understanding it right, that would tag all the traffic with DSCP 40, not 46. Should I create a new qosprofile or adjust the QP6 codepoint mapping. If so, how do I change the codepoint mapping from 40 to 46?
EDIT:
Of course not 10 seconds after posting this I found the command to change the QP6 code-point, now it shows:
Rocket1.36 # sh diffserv replacement QOSProfile->CodePoint mapping: QP1 -> 00 QP6 *> 46 QP8 -> 56
Is the * there after QP6 because I've changed it from default? Will that cause any issues?
