Maybe a stupid question but here it goes..
I have a 6248 with 4 vlans. 3 vlans are for regular data traffic and one vlan for video traffic. The three vlans for data are routable with IP interfaces so they talk to each other. The vlan for video is isolated and only a video communication system goes here.
My question is since the only traffic flowing in this vlan is the video traffic, do I need to configure QoS on this vlan? Users are experiencing really poor video quality with a lot of packet drops. In that case how do I apply QoS on that vlan.
The 6248 is trunked with a 5548 where the video equipment is attached.
