Description: When this variable is set to 'true', DHCP Snooping will verify that the MAC address in the chaddr field of the DHCP header matches the source MAC address in all DHCP packets received on untrusted ports. When this variable is set to 'false', DHCP Snooping will omit this check. The value of this variable is ignored when DHCP Snooping is disabled.
What is hpicfDhcpSnoopVerifyMac?
When set to true, this option makes DHCP Snooping check that the client hardware address (chaddr) inside each DHCP packet arriving on an untrusted port matches the packet's actual source MAC address, dropping packets where they disagree. Admins enable this to catch spoofed DHCP requests; the check is skipped entirely if DHCP Snooping itself is disabled or if this is set to false.
