dot11Disassociate
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11Disassociate
OID (numeric): 1.2.840.10036.1.6.0.1
Node type: NOTIFICATION-TYPE
Description: The disassociate notification shall be sent when the STA sends a Disassociation frame. The value of the notification shall include the MAC address of the MAC to which the Disassociation frame was sent and the reason for the disassociation.
ifIndex - Each 802.11 interface is represented by an ifEntry. Interface tables in this MIB module are indexed by ifIndex.
What is dot11Disassociate?
This is a notification event sent when a wireless station (STA) disconnects from an access point by transmitting a Disassociation frame. The notification includes the MAC address of the access point being disconnected from and the reason code explaining why the disconnection occurred. Network operators use this to monitor wireless client disconnection events for troubleshooting connection reliability and understanding client behavior.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' IEEE802dot11-MIB::dot11Disassociate snmptrap -v2c -c public <manager> '' 1.2.840.10036.1.6.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:57431->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (226871895) 26 days, 6:11:58.95 SNMPv2-MIB::snmpTrapOID.0 = OID: IEEE802dot11-MIB::dot11Disassociate
