Hi Deepak
I presume you mean how to collect via SNMP or did you mean from CLI ?
You can collect/monitor info about any auth source (be it radius, internal or tacacs etc.) from the SNMP MIB specifically wlsxAuthenticationServerTable OID. I am not sure what you mean that it doesnt need to be based on aaa auth, as this is the only place it would show auth rate/success - can you clarify what you mean ?
The equivalent CLI command has to be run against each server type, i.e. for radius you would use "show aaa authentication-server radius statistics"
'session drop rate due to interference' is not something that can really be measured. For detecting APs with high interference, you can monitor this from SNMP using wlsxWlanAPChStatsTable. Where you need to derive interference by the following:
interference = wlanAPChUtilization - wlanAPChTxUtilization - wlanAPChRxUtilization
for example, for some AP (here 18:64:72:c6:6b:ea) which has 2 radios active, where [1] is 5ghz, then for each band we can determine the interference is as follows:
$ snmpwalk -v2c -c public -mALL -M. -O0X 10.1.2.3 wlsxWlanAPChStatsTable | grep 18:64:72:c6:6b:ea | grep Util
WLSX-WLAN-MIB::wlanAPChRxUtilization[STRING: 18:64:72:c6:6b:ea][1] = INTEGER: 2
WLSX-WLAN-MIB::wlanAPChRxUtilization[STRING: 18:64:72:c6:6b:ea][2] = INTEGER: 34
WLSX-WLAN-MIB::wlanAPChTxUtilization[STRING: 18:64:72:c6:6b:ea][1] = INTEGER: 0
WLSX-WLAN-MIB::wlanAPChTxUtilization[STRING: 18:64:72:c6:6b:ea][2] = INTEGER: 0
WLSX-WLAN-MIB::wlanAPChUtilization[STRING: 18:64:72:c6:6b:ea][1] = INTEGER: 5
WLSX-WLAN-MIB::wlanAPChUtilization[STRING: 18:64:72:c6:6b:ea][2] = INTEGER: 53
radio [1] = 5 - 2 - 0 = 3% interference on 5ghz
radio [2] = 53 - 34 - 0 = 19% on 2.4ghz
or you can use the CLI command "show ap radio-summary" and refer to the column named "NF/U/I" where the "I" value is the same as shown above, within a few % since I ran these two commands at slightly different times.
