Also, the WLC needs a trap receiver configured ( Management > SNMP > Trap Receivers) on the GUI as well. Background Informationįor each AP dissociation/association event, the WLC must send a SNMP trap with the following Object Identifiers (OIDs):ġ.3.6.1.2.1.1.3.0 (sysUpTime) SNMP > Trap Controls > AP > AP Register). If your network is live, ensure that you understand the potential impact of any step. All of the devices used in this document started with a cleared (default) configuration.
