Client Association Successful / Failed

[td_td]

How will the SCG / ZD determine a failed associations and what is the main reason of the failed association?

Will it related to frequency jam? or Will it related to the maxium number of client the AP supported?

[td_td]

Or may I check it on the SCG to get those info?

[td_td]

I think I found it some like reason=?

or other location?

As I found some log stated "Calling node_leave as Assoc capacity reached on Test if reach the configured SSID limit

[monnat_systems]

Will it related to frequency jam? not possible as during frequency JAM...there is no communication possible however for a situation to lead to association failure, STA need to do probing, clear authentication and then comes association stage.

or Will it related to the maxium number of client the AP supported?

yes, its possible. see Code-17 Association denied; the access point is resource constrained. AP's capacity to handle client is full or near full. this may happen.

Someone in ruckus can confirm how AP is expecting to behave if client limit reaches max

[td_td]

So will there any possible way to check it myself first by AP log or SCG log? Since at that time nearly 100 client on 2.4G and 100 client on 5G that concurrent using on the single AP Where can I get those log?

if you are in the CLI of the AP you can run "get syslog log"

Although as already mentioned above you are better getting the supportinfo.txt file from the AP (obtained via web ui) - this will also help you look at possible radio related issues like airtime utilisation per radio:

------------ Airtime Stats ------------
Airtime utilized (percent) since clearing delta stats (1 sec)
   Busy:100    RX:  0    TX:  0    Total:100
Histograms of airtime (pcttime in each range) since clearing all stats
        0  0-10  ..20  ..30  ..40  ..50  ..60  ..70  ..80  ..90 ..100
busy:  14     0     0     0     0     0     0     0     0     0    86
rx:   100     0     0     0     0     0     0     0     0     0     0
tx:   100     0     0     0     0     0     0     0     0     0     0
tot:   14     0     0     0     0     0     0     0     0     0    86


The above shows a radio fault which will kick clients and make the radio interface unusable (requires RMA)

The below is what I would expect to be seeing:

------------ Airtime Stats ------------
Airtime utilized (percent) since clearing delta stats (1 sec)
   Busy:  3    RX: 30    TX:  0    Total: 33
Histograms of airtime (pcttime in each range) since clearing all stats
        0  0-10  ..20  ..30  ..40  ..50  ..60  ..70  ..80  ..90 ..100
busy:  13    76    11     0     0     0     0     0     0     0     0
rx:     0    65    22    12     1     0     0     0     0     0     0
tx:    95     5     0     0     0     0     0     0     0     0     0
tot:    0    47    25    14    13     1     0     0     0     0     0

I have a couple of questions for you:

Is your question in relationship to you witnessing an AP drop clients when the AP is loaded with 100 clients on each radio?

If so, what AP type are we talking about here, and what happens after, does the AP reboot?

If the AP reboots then you have lost your syslog, but you can always contact support and get them to enable himem which will retain logs on reboot
