eSWIPSpoofing
Module: ASANTE-SWITCH-MIB
OID (symbolic): ASANTE-SWITCH-MIB::eSWIPSpoofing
OID (numeric): 1.3.6.1.4.1.298.0.5
Node type: NOTIFICATION-TYPE
Description: This trap is caused by the detection of a duplicate IP address. It means that there are 2 or more stations using the same IP address. The first three parameters are the IP address, MAC address, and port number of the existing workstation. The remaining three parameters are the IP address, MAC address, and port number of to the workstation which is trying to spoof the network environment. Therefore, the IP addresses should be the same, but the MAC addresses are different.
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> '' ASANTE-SWITCH-MIB::eSWIPSpoofing snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.298.0.5
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]:63921->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (241445809) 27 days, 22:40:58.09 SNMPv2-MIB::snmpTrapOID.0 = OID: ASANTE-SWITCH-MIB::eSWIPSpoofing
