SLB-mode

What are the operational details of the "channel and radio based" mode - there is no explanation in the guides of how this mode operates.

Re: SLB-mode

This feature, Spectrum Load Balancing is supposed to

 

- Group access points into "Neighborhoods"

- Load Balance Clients among those groupings either by radio or number of clients.

 

Spectrum Load Balancing has been replaced by Client Match in Instant 4.2.x.x

Re: SLB-mode

Well, on 6.4.4.8-4.2.4.3 (ED) these commands are still present.

And this is what interests me.

 

We can configure a ClientMatch client threshold which is a 'Number of clients associated to each radio before the SLB algorithm kicks in' with default 30 clients per radio.

arm
   client-match client-thresh {threshold}

and then we have possibility to configure SLB mode, under Client-Match commands in ARM profile

   client-match slb-mode {1:Channel based; 2:Radio based; 3:Channel+Radio}

Are those (SLB) settings not used for client load-balancing by ClientMatch feature on Instant?

Re: SLB-mode

Spectrum Load Balancing is an integrated configuraton component of Client Match.  In the past, it was separate.

Re: SLB-mode

Ok, thanks.

So is:

arm
   client-match client-thresh {threshold}

the same setting as CM threshold in GUI?

Sorry to be such a pain in the ... but just want to be sure, because descriptions for both suggest these two configure different things.

For example:

For CLI: When the number of clients on a radio exceeds the value, SLB algorithm will be triggered.

For GUI: acceptance client count difference among all the channels of Client match into account.

Re: SLB-mode

So, there are some ARM ClientMatch tuning parameters that can only be changed in the CLI (7 of them), instead of the GUI on Instant .  You will find those additional commands along with the descriptions in the CLI Guide here:  https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/Command/Core_Download/Default.aspx?EntryId=22480 starting on page 39.

 

EDIT:  To directly answer your question, the "CM Threshold" in the GUI corresponds to the "calc-threshold" commandline parameter.

 

The GUI of the controller also ONLY has a few CM commands in the GUI (with the rest being on the commandline).
