QOS on Cisco 3600 Autonmous AP

[Abdel Amyay]

Hello,

We have our guest SSID, seperate vlan,  running on our production APs with an IP filter on APs and Layer 3 switches. The Guest SSID has access to DHCP internally and internet only. I am tasked to cap the throughput on Guest SSID to limit the bandwidth usage when going to the internet.

What s the best practice to approach this. Should I classify and mark traffic on access points and do QOS on the layer 3 switch? Is there somewhere on the AP where I can cap the throuput?

Thanks

When rate limiting, you should always place that near the point of traffic.

For guest i would implement rate limiting at the L3 edge that is connecting to the internet.

HTH,

Steve. Thanks for the quick response.

So if my internet circuit is 20 Mbps, I should create two ACLs one for Guest and the other for the rest of the users. Then I should create two classes for the above traffic  and create a polocy that would police Guest traffic to 2 Mbps and shape default traffic to 18 Mbps.

Will that work?

[Stephen Rodriguez]

That should work

Yes, you can use two ACLs for Guest and rest of the users. You can then create 2 classes and police Guest to 2-4 Mbps and shape default traffic to 16-18 Mbps.
