My company is getting Microsoft OCS (Unified Communication) installed, and therefore I need to configure QoS for Voice And Video. It's gonna be softphone (Microsoft Office Communicator) so I cannot segment the Voice and Video traffic into sepereate VLAN's, the Voice/video data is gonna flow on the normal Data VLAN.
All of our switches is HP and all of our routers is Cisco.
We have 9 departments, all with some Access layer switches (HP) that connects to a Cisco router, the routers then connect to our Core Switches in the Datacenter.
My question is...:
Do I need to mark the traffic with som COS values on the Access switches, or should I just create some LLQ queues on the routers that match the DSCP value from the Client? Can the DSCP value in the IP packet go from the client though the Access switche (layer 2) and still remain their DSCP value when hitting the routers?
Correct me if i'm wrong, but as I have understood it, is it not possible to make any QoS / traffic priority on a layer 2 switch, it's only possible to mark traffic. But when my clients are marking the traffic, i dont see why i should do any COS (layer 2 marking)
So will it be enough to just match the DSCP values on the routers, without any switch config.
But it's it correct understood that a layer 2 device cannot make any QoS/traffic priority, they can only mark traffic with COS values 802.1p right?
On the other hand I see a problem in trusting DSCP directly from the clients, they could manipulate with the ip packet and send wrong DSCP values with traffic that should not have high priority - right?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
