Description: Enable/disable validating of the source media access control (MAC) address against the link-layer address.
What is rlNdInspectionPolicyValidateSrcMac?
This read-write RlIpv6FhsSettingStatusType in the ND inspection policy table enables or disables validating that a neighbor discovery message's source MAC address matches its link-layer address option. An admin cares because this check catches a classic spoofing technique where the claimed link-layer address doesn't match the actual Ethernet source, which plain ND inspection without this check would miss. For example, enabling this on policy "ndi-access" causes ND inspection to drop a Neighbor Advertisement whose embedded link-layer address doesn't match the frame's real source MAC.
