snoopingPortConfigMacAddressVerification
Module: G6-DHCP-MIB
OID (symbolic): G6-DHCP-MIB::snoopingPortConfigMacAddressVerification
OID (numeric): 1.3.6.1.4.1.3181.10.6.2.49.9.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When a packet is received on an untrusted interface, and the source MAC address and the DHCP client MAC address do not match and this feature is enabled, the packet is dropped.
What is snoopingPortConfigMacAddressVerification?
When enabled, packets arriving on an untrusted port are dropped if the Ethernet source MAC address doesn't match the DHCP client MAC address inside the packet, catching a common DHCP-spoofing technique.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3181.10.6.2.49.9.1.6 snmpwalk -v2c -c public <target> G6-DHCP-MIB::snoopingPortConfigMacAddressVerification
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3181.10.6.2.49.9.1.6.1 snmpget -v2c -c public <target> G6-DHCP-MIB::snoopingPortConfigMacAddressVerification.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.3181.10.6.2.49.9.1.6.1 i <value>
