Enabling MFF
Restrictions and guidelines
An MFF-enabled device and a host cannot ping each other.
When MFF works with static IP source guard bindings, you must configure VLAN IDs in the static bindings. Otherwise, IP packets allowed by IP source guard are permitted even if their destination MAC addresses are not the MAC address of the gateway.
MFF is not supported in a network where VRRP load balancing mode is configured.
Prerequisites
For MFF to take effect, make sure ARP snooping is enabled on the VLAN where MFF is enabled.
