SNMP Clarification. Number of Stations Reported do not match Number of Stations listed by RuckusZDWLANStaTable

unknown

We're trying to understand the ZoneDirector SNMP tables better.
 (we've testing with ZD1100 v9.8.2  and ZD1200 v9.10.2)

We observe that the number of reported stations is different depending on the table use:
for example,





ruckusZDSystemStatsNumSta
1.3.6.1.4.1.25053.1.2.1.1.1.15.2
here we get 56

does not match the listed number of stations by:




ruckusZDWLANStaMacAddr
1.3.6.1.4.1.25053.1.2.2.1.1.3.1.1.1
here we get 68

Any suggestion? (are we misunderstanding this)

How often are the Statistics updated in:
ruckusZDSystemStats


Regarding a specific (Stations) TX & RX BW usage in bytes:
ruckusZDWLANStaTable




ruckusZDWLANStaRxBytes
1.3.6.1.4.1.25053.1.2.2.1.1.3.1.1.11



ruckusZDWLANStaTxBytes
1.3.6.1.4.1.25053.1.2.2.1.1.3.1.1.13

Are these zeroed after each Association Period?  (in other words, when they disconnect)

What happens if a Station MAC reconnects again later in the day, is this BW usage accumulated or is the usage reported for a specific Association Time?

Thank you for all taking time to help us understand.
