eltIpArpInspectPortNumOfArpMismatched
Module: ELTEX-MES-BRIDGE-SECURITY
OID (symbolic): ELTEX-MES-BRIDGE-SECURITY::eltIpArpInspectPortNumOfArpMismatched
OID (numeric): 1.3.6.1.4.1.35265.1.23.112.7.1.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of dropped ARP packets that were not validated by ARP inspection and inconsistency was found for IP and MAC (mismatch)
What is eltIpArpInspectPortNumOfArpMismatched?
This read-only counter tracks specifically how many ARP packets on this interface were dropped because the sender's IP and MAC address didn't match the switch's trusted bindings. A rising count here strongly suggests ARP spoofing/poisoning attempts on this port.
Examples
