This object carries the MAC address of a wireless client involved in an event, and is included as a variable binding in the corresponding SNMP trap sent by a Ruckus wireless controller or access point. A network administrator reads this value from a received trap to identify exactly which client device triggered the event, such as an association failure or rogue detection. For example, ruckusEventClientMacAddr in a deauthentication event trap identifies which specific laptop or phone was disconnected from the wireless network.
