ip mac-validate

Syntax

ip mac-validate [ strict | loose ]

no ip mac-validate

Release Information

Command introduced before JUNOSe Release 7.1.0.

Description

Enables MAC address validation on a per interface basis. When MAC address validation is enabled, the router checks the entry in the MAC validation table that corresponds to the IP source address of an incoming packet. The MAC source address of the packet must match the MAC source address of the table entry for the router to forward the packet. The no version disables the feature.

Options

strict—Prevents transmission of IP packets that do not reside in the validation table
loose—Allows IP packets to pass through even though the packets do not have entries in the validation table; only packets that have matching IP–MAC pair entries in the table are validated
