arpInspectionPortConfigSourceMacValidation
Module: G6-DHCP-MIB
OID (symbolic): G6-DHCP-MIB::arpInspectionPortConfigSourceMacValidation
OID (numeric): 1.3.6.1.4.1.3181.10.6.2.49.12.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Checks the source MAC address in the Ethernet header against the sender MAC address in the ARP body. This check is performed on both ARP requests and responses. Packets with different MAC addresses are dropped.
What is arpInspectionPortConfigSourceMacValidation?
When enabled, drops ARP packets (both requests and responses) where the Ethernet header's source MAC address doesn't match the sender MAC address carried inside the ARP payload, catching a classic ARP-spoofing mismatch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3181.10.6.2.49.12.1.7 snmpwalk -v2c -c public <target> G6-DHCP-MIB::arpInspectionPortConfigSourceMacValidation
Get a specific instance (index 1):

Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.3181.10.6.2.49.12.1.7.1 i <value>
