dot11Deauthenticate
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11Deauthenticate
OID (numeric): 1.2.840.10036.1.6.0.2
Node type: NOTIFICATION-TYPE
Description:
The deauthenticate notification shall be sent when the STA sends a Deauthentication frame. The value of the notification shall include the MAC address of the MAC to which the Deauthentication frame was sent and the reason for the deauthentication.
ifIndex - Each 802.11 interface is represented by an ifEntry. Interface tables in this MIB module are indexed by ifIndex.
What is dot11Deauthenticate?
This OID triggers an alert when a wireless client disconnects and sends a deauthentication frame, including the client's MAC address and the reason for disconnecting. The alert helps operators track which devices are leaving the network and why. A WiFi administrator investigating excessive dropouts reviews these alerts to see if certain devices, clients, or reasons for disconnection are recurring.
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::dot11Deauthenticate snmptrap -v2c -c public <manager> '' 1.2.840.10036.1.6.0.2
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:
