I need help to interpret a portion of Client Session report in Prime Infrastructure. I placed a call with TAC and the engineer was unable to explain what the output means (for which I am si disappointed)
|Client Username||Association Time||AP Name||Session Duration||Avg. Session Throughput(Kbps)||SNR (dBm)||RSSI|
|0160mp1||2015-Nov-29, 12:38:43 EST||0160APFR2||40min 2sec||3.5||0||-128|
I'd like to know what it means when the device is showing an SNR of 0 and an RSSI of -128. Technically the device should be unreachable on the network, however my monitoring tool doesn't show it as down! So the device is reachable but the RSSI is -128! It doesn't make sense to me!
And also, session duration is 40 min 2 sec, doesn that mean during 40 minutes the RSSI was -128? Or this value is just a sample?
Thanks for your help,
