dhcpSnoopingPortConfigMacVerify
Module: TPLINK-DHCPSNOOPING-MIB
OID (symbolic): TPLINK-DHCPSNOOPING-MIB::dhcpSnoopingPortConfigMacVerify
OID (numeric): 1.3.6.1.4.1.11863.6.27.1.3.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 0. disable 1. enable Select Enable/Disable the MAC Verify feature. There are two fields of the DHCP packet containing the MAC address of the Host. The MAC Verify feature is to compare the two fields and discard the packet if the two fields are different.
What is dhcpSnoopingPortConfigMacVerify?
This read-write integer enables (1) or disables (0) the MAC Verify feature on a port under DHCP Snooping. Per the description, DHCP packets carry the client's MAC address in two separate fields, and when enabled the switch compares them and discards the packet if they don't match, guarding against MAC address spoofing. For instance, an admin enables dhcpSnoopingPortConfigMacVerify on client access ports so a host can't fake its hardware address in the DHCP request while presenting a different one at Layer 2.
