WLC Bandwidth Shaping

[Dr Why]

Hi,

I don't understand the differences between limiting the data rates on a per-user basis, versus limiting the data rates on a per-SSID basis.

Could someone please provide me some practical examples to help me to clarify ?

On a per-SSID basis scenario if for example there are 5 AP with a WLAN "foo" configured with a bandwidth limit of 20Mbps Down and 10Mbps Up, is this limit applied to each WLAN on each AP for whole value or is it shared accross between the WLANs "foo" on each APs ?

Thank you in advance

Hi 

Let's take an example for explanation:

Let's say the bandwidth is limited to 20Mb for the SSID. That means if you have 10 clients, each one will have a bandwidth of 20Mb/nb clients. In our example it's 2Mb. More clients you have less bandwidth they get. 

If you limit 2Mb per user that means each one will have 2Mb. No matter how many clients you have each one will be served with a max of 2Mb. 

Hope that's clear 

Thanks

Hi,

thanks for the answer! From the QoS configuration panel for WLAN it seems that you can also limiting the data rates on a per-user basis AND per-SSID basis, if for example the bandwidth is limited to 20Mb for the SSID and 2Mb for the user,when the number of clients are more then 10 in this case how does the WLC limits the bandwidth ?

Thanks

Hi 

If I'm not wrong the SSID rates limit should take precedence. 

Thanks
