Limit bandwidth per SSID using radio limits

Hi All,
I have a question that I am sure someone will be able to answer really easily.
I have tried setting a bandwidth limit on my IAP105 on my test network.  I have set this to 15Mbps, however the throughput chart is showing in excess of 20 Mbps.


Looking a bit closer, it seems that its set per radio.  My initial assumption is that this is now set to 15 Mbps for b/g/n and 15 Mbps for a / ac

 

I have attached 2 screen grabs, showing the limit I have set and the helper text.

 

What I am trying to achieve is that no more that 15 Mbps can be used by wireless users to protect the network for my wired users.

 

Should I set the limit per radio at 7.5 Mbps to give a total throughput of 15 Mbps or am I completely off the mark??

 

Thanks in advance

It should be like the description, yes.

Re: Limit bandwidth per SSID using radio limits

Hi Colin,

 

Thanks for the reply. 

 

I dont understand what you mean? To get 15 meg overall, i need to set the radio limits at 7.5 meg each (7.5 for 2.4Ghz and 7.5 for 5Ghz)?

 

Sorry, I am having one of those weeks :)

 

TIA

Re: Limit bandwidth per SSID using radio limits

If you want to limit the bandwidth for your wireless users, you should do it on the role level;  http://www.arubanetworks.com/techdocs/Instant_42_WebHelp/InstantWebHelp.htm?_ga=1.43038629.1615771646.1440445030#UG_files/Roles_and_policies/ConfUserRole.htm

 

Put user in a role - configure that role to only allow 15 megabits/second.  That way you don't have to make separate configurations for the radios.

 

Honestly, wireless traffic backs off from contention far more than wired traffic, so you have less bandwidth issues to worry about there, unless you have a 1 megabit circuit.

Re: Limit bandwidth per SSID using radio limits

and yes, the bandwidth limits are per radio so on a dual radio AP you would limit to 7.5 if you want the total max output to be 15. 

If you would have mixed dual radio and single radio AP's this would mess it up a bit.
