I have two sites connected using 600Mbps (CIR) terminated as a fiber link provided by the service provider. The WAN devices are C3750G, IPS image. So one C3750G is in site-A (C3750G-A) and one C3750G in site-B (C3750G-B).
From the LAN side I have two separate networks (LAN-1 and LAN-2) in site A and two separate networks in site B (LAN-1 and LAN-2), so I already configured VRF-lite for this on the WAN by configuring the WAN link is a trunk with two VLANs and terminated the two VLANs in to two SVIs, and two VRFs is configured.
The LAN-1 in site A can speak to LAN-1 in siteB, LAN-2 in site A can speak to LAn-2 in site B.
The problem is that LAN-1 contains corporate users that are consuming the bandwidth between the two sites so I want to rate limit the traffic between LAN-1 in the two sites to 100Mbps and leave the remaining bandwidth for LAN-2. On the other hand in LAN-2 I have video, audio and FTP and I want to give high priority for the video and audio.
So what is the best QoS for this scenario? I have good understanding of QoS MQC. But I read in the manual that C3750 support another features like mls qos. So can I use MQC or I have to use âmls qosâ configurations? Please advice?
