snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps tty
snmp-server enable traps entity
snmp-server enable traps disassociate
snmp-server enable traps deauthenticate
snmp-server enable traps authenticate-fail
snmp-server enable traps dot11-qos
snmp-server enable traps switch-over
snmp-server enable traps rogue-ap
snmp-server enable traps wlan-wep
snmp-server enable traps config
snmp-server enable traps syslog
snmp-server enable traps cpu threshold
