SNMP TRAP WLC 5508

[mdrangell22]

Hello guys

I have a WLC 5508 Software 8.0.133.0 and I configured the following SNMP Traps:

General: Link (port) Up/Down

AP: AP Register and AP Interface UP/DOWN

But my monitoring team is receiving this trap KTS VOIP CALL FAILURE:

"A "ciscoLwappKtsVoipCallFailureNotif" event has occurred, from GnCiscoDev device, named WLC-XXXX"

If I only checked 3 options in SNMP trap why My team is receiving this trap? And what this trap mean? I have tried to find information and I don't find something specific aside this is the OID

.1.3.6.1.4.1.9.9.524.0.5

maybe you've got the wrong mibs loaded?

according to this link the mib value of "ciscoLwappKtsVoipCallFailureNotif"  is different

you may need the  http://www.circitor.fr/Mibs/Html/C/CISCO-LWAPP-AP-MIB.php

and oid's

searching for VOIP call failure I found this:Cheat-Sheet-Common-Wireless-issues

VoIP Call Failure: '1x:xx:1x:xx:xx:xx' client, detected by 'xx-xx-xx' AP on radio type '802.11b/g'. Reason: 'Call failed: TSPEC QOS Policy does not match'.
Means platinum QoS was not configured on WLAN

hope this helps
