QoS and switching

[TinRam]

Hello... Question for you gurus

If QoS is in use on our video conference system, what happens if the switch gear between the video conference system and the router is not QoS compliant? (3com Surestack) Will it strip the frame tag or will it just pass it along? Is it dependant on the switching type (store & forward, fragment free, etc.)? If it forwards the frame without stripping the frame tag out, all is good. However if it is stripping the tag, we have a complication. If the frames getting to the router don't have QoS tagging, the router will have to tag all frames from the Vid system with QoS.

Can anybody give me some tips here?

What tagging are we talking, 802.1p, Diffserv DSCP???

If its layer 2 tagged and the 3com isn't 802.1p/q compliant, the frames will get dropped because it doesn't know what to do with them. If its layer 3 tagged, then the 3com will work...
