Limit bandwidth per SSID

Hello,

Is there any possibility to limit the bandwidth per SSID on Cisco Aironet 1100 that is connected to Cisco router 876?

So the main goal is to have two SSID one for the guests and one for the colleagues and to limit for example half the bandwidth of internet link per SSID so we dont get into situation that colleagues overload whole internet link so that guests can always surf without problem.

Few Facts:

IF you are talking about autonomous AP:

- Upstream traffic from the wireless client

QoS for wireless LANs does not affect this traffic.

-The Ethernet upstream flow is traffic sent from  the access point Ethernet port to a switch or router on the wired LAN.  The access point does not prioritize traffic that it sends to the wired  LAN based on traffic classification.

Based on the above , if you want to divide the bandiwdth from two ssids users accessing the internet

you have to define two clss maps , based on the source ip address subnet given that every ssid is mapped to different vlan , hence different subnet . This should be done on the first l3 hop device .

based on the two class maps you have to configure policing based on the internet available bandwidth .

Dear Maldehne,

Upstream traffic sent from Access Point is not our concern - only the downstream.

As I have no experience with class and policy maps - could you please help me creating this two class maps?

I have read the Cisco guide to configuring class maps and policy maps, but unfortunately I cant figure out how could I create the necessary..

well, you need to create two ACLs

one ACL to match traffic sourced by certain subnet that represent clients on ssid 1

another ACL to match traffic sourced by the other subnet the represent ssid 2

Then you create two class maps and use to match the ACL that is alligned with each class

configure policing based on the classes the you have created using policy map

Then apply it

Hi,

I haven't come across this type of issue

But information is provided on below link is complete, so where you are stucking ?.

You can use QOS to do this. When you configure QoS on the access point, you can select specific network traffic, prioritize it, and use congestion-management and congestion-avoidance techniques to provide preferential treatment. Implementing QoS in your wireless LAN makes network performance more predictable and bandwidth utilization more effective. For more information on this read the document available at http://www.cisco.com/c/en/us/td/docs/wireless/access_point/12-2_11_JA/configuration/guide/b12211sc/s11qos.html
