9800 vs AireOS snmp traps

[k.gabelsberger]

I'm trying to configure the 9800 snmp traps similar to AireOS.  I'm comparing 9800 version 17.2 to AireOS 8.5.  I have the following configured on the 9800:

snmp-server enable traps wireless bsnMobileStation bsnAccessPoint bsnGeneral AP wireless_mobility
snmp-server enable traps rf
snmp-server host 1.2.3.4 version 2c secret

In AireOS, I would commonly see the following snmptrap OIDs:

ciscoLwappDot11ClientAssocDataStatsTrap
bsnDot11StationAssociate
ciscoLwappDot11ClientMovedToRunState
ciscoLwappDot11ClientSessionTrap
bsnDot11StationDeauthenticate
ciscoLwappDot11ClientDisassocDataStatsTrap

In 9800, I don't see those types of events logged.  What configuration am I missing?

If possible upgrade to 17.3.1 & test.

There are some bugs listed that may be related (an example is given below. It is fixed in 17.3.x, so worth upgrading first)

9800 Controller does not send SNMP Trap when AP is reset using the GUI or CLI

CSCvs29013

Description

Symptom:
SNMP Trap for an AP being reset manually from the 9800 Wireless Controller GUI or CLI does not get generated.
Nor is the trap generated when the AP joins back

Conditions:
9800 WLC configured to send SNMP Traps and AP traps are enabled

Workaround:
Enter "trapflag AP register" in the Controller CLI.

Further Problem Description:
This command should be enabled by default in order to have the traps sent.
The fix would include this to be enabled out-of-the-box.

Upgrading to 17.3.1 plus adding all the applicable trapflags solved the issue!  Thank you!
