The auth throttling feature was introduced in AOS 6.3 code version to prevent high cpu utilization for Auth process.(Aruba3600) #show dot1x counters 802.1x CountersThrottling CountersDot1x high watermark..................200Dot1x low watermark...................190Dot1x stm throttling percent..........50Dot1x auth pass count.................22Dot1x auth fail count.................2447Double dot1x context init counts......269/269Active dot1x station count............0Max collisions in active table........0Pending station count.................0Max collisions in pending table.......0AP Up.............................34 Down...........................34 Acl............................10Station Up.............................2944 Down...........................2657EAP RX Pkts........................63 EAPOL-Failure...................2447 TX Pkts........................65WPA Message-1......................22 Message-2......................21 Message-3......................22 Message-4......................21 Group Message-1................21 Group Message-2................21Radius Accept.........................22Station Deauths.................2449When "Active dot1x station count" reaches high watermark, requests start being put in Pending queue.If "Active dot1x station count" is between high and low water mark, then active queue requests are processed, but pending queue requests are not processed.If "Active dot1x station count" is below low water mark, then both active clients and pending clients get processed.If "Pending station count" reaches 80% of the active queue, then STM module on the controller will drop the new requests until pending queue is below 80% of the active queue. In this situation, we will see the "associations dropped due to auth throttling" will increase.(Aruba3600) #show ap debug client-mgmt-counters | include ThrottAssociations Dropped Due to Auth Throttling 0In this case, device will have to try again.Dot1x throttling is applied for dot1x termination and non-termination cases.Following are the default platform configurations:Platform HighWaterMark (HWM LowWaterMark(95%of HWM)7210 550 5227220 600 5707240 750 712M3 450 4273600 200 1903400 60 573200 40 38600 20 19
