dhcpSnoopVerifyMACAddress
Module: AT-GS950-8-MIB
OID (symbolic): AT-GS950-8-MIB::dhcpSnoopVerifyMACAddress
OID (numeric): 1.3.6.1.4.1.207.1.4.165.181.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Determine if to verify MAC address for incoming DHCP packets.
What is dhcpSnoopVerifyMACAddress?
Controls whether the switch verifies that the source MAC address in the Ethernet frame matches the client hardware address field in the DHCP packet, helping to prevent MAC spoofing attacks. When enabled, mismatched packets are dropped before they can be forwarded.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.207.1.4.165.181.4 snmpwalk -v2c -c public <target> AT-GS950-8-MIB::dhcpSnoopVerifyMACAddress
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.207.1.4.165.181.4.1 snmpget -v2c -c public <target> AT-GS950-8-MIB::dhcpSnoopVerifyMACAddress.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.207.1.4.165.181.4.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dhcpSnoopVerifyMACAddress.1
