Management capacity of WiNG Virtual controller

Son_Nguyen2 — Wed, 13 Dec 2017 22:26:00 GMT

Hi community,

Could someone let me know the management capacity of a WiNG AP (virtual controller) such as max concurrent clients, user entry, WLAN,...like a real controller.

Thanks so much.

You can find most information in the data sheet.

The limit is maybe not at the controller, but at the RF Domain.

For example a AP can just "control" 128 per RF Domain. With the AP84xx, AP85xx and AP7632 the limit is extend to 256 APs.

To you would build one big network or manage several locations?

Thank you Timo, but I want to know some information not shown in the datasheet such as limited concurrent clients per site, limited user entry, WLAN, user database with Virtual controller?

You can get this information from your local Extreme Networks SE.

I'm sure, that there are some documentation where you can get this information. But you need to point your needed information.

Client count for example is 128 or 256 per radio. I think it depend on you AP type. Also that's a number you hopefully would never see on a AP, because it's mostly not possible.

Thanks Timo, the important information I need to know is the limitation of Captive portal database of entire wifi system when using Virtual controller mode with internal Radius server?

Hi Son;
Here is the datasheet for the ExtremeWireless™ WiNG VX 9000 Controller

Thanks Robert, but I want the information of the Virtual controller by using an AP?

Hello Son Nguyen,

From my own experience, for example AP7502 you can create 2 simultaneous SSH sessions but when creating the 3 or 4 connection is prohibited with out of RAM message. When with AP6532 or the newest AP models don't had that problems. So only limitation is RAM.
If you searching for a management configuration limitation of device, I can give you a direction to see in to the config file in the internal memory of your device. Update me if you want to know the file path.

Regards,

Aviv

Hello,

Check here with CLI for limitations:
more system:/proc/dataplane/limits

Otherwise your limit is the RAM memory.

Aviv

Thank you so much Aviv. Can I get the limitation of Captive portal database of entire wifi system when using Virtual controller mode with internal Radius server?

Hello Son,

I don't sure for 100% but maybe this limitation is the file descriptors, you can check with CLI:

AP-lab>service show sysinfo

AP6521 have a limit of 128 local radius user. All other APs limited by 256 user in the database.

This user can be EAP-MSCHAPv2 or Captive Portal user.

If you use local radius with LDAP as database, there is no limit. Also for PEAP-TLS or TLS there is "no limit", because in both cases the database is not local. Same, if you use central VX or NX. The limit is for the user database mapped on an AP.

Thank you Timo, very clear information.
