3550 24 port SMI / EMI QoS

[darylhunter]

Hi there... consider the following scenario:

3550 24 port EMI at 172.168.20.7 (Campus 1) - first switch seen at this campus, uplinked to the "transparent lan" fibre

3550 24 port SMI at 172.168.21.3 (Campus 2) - first switch seen at this campus, uplinked to the "transparent lan" fibre

Both with IOS 12.1(13)EA1a

connecting the two campuses is a 100 Megabit fibre connection

lots of different traffic goes across this link but one particular type is more important than any other

On the backend of campus 1 is a 192.168.1/24 network

On the backend of campus 2 is a 192.168.2/24 network

We are doing MPEG streaming across the 100 Meg fibre and that needs to be the MOST IMPORTANT information.

That video comes from 192.168.1.250/24 and goes to 192.168.2.250/24 and also vice-versa

So, any traffic that goes between 192.168.1.250 and 192.168.2.250 is the most important

Other things need to go, but always behind the video.

So, did you catch that? Video from 192.168.1.250 is routed into 172.16.20.7 and then sent across the fibre along with other data, VoIP traffic to 172.16.21.3 and then routed toward 192.168.2.250.

How would I go about marking all traffic between those two 192.168.1.250 and 192.168.2.250 IPs as being most important?

Consider my QoS knowledge minimal.

I don't mind learning and reading, but get me started please.

Thanks,
