Description: A a3BogusDhcpSvr trap signifies that an unauthorized DHCP or BOOTP server has been detected on the network.
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> '' A3Com-System-r8-MIB::a3BogusDhcpSvr snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.43.0.100
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]:54986->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (133012682) 15 days, 9:28:46.82 SNMPv2-MIB::snmpTrapOID.0 = OID: A3Com-System-r8-MIB::a3BogusDhcpSvr
