Configuring a Blackhole MAC Address Entry

Configuring a Blackhole MAC Address Entry

Blackhole MAC address entries can be used to filter out invalid MAC addresses.


To protect a device or network against MAC address attacks from hackers, configure MAC addresses of untrusted users as blackhole MAC addresses. The device then directly discards the received packets of which the source or destination MAC addresses match the blackhole MAC address entries.


The AR510 series do not support blackhole MAC address entry.

The 4GE-2S cards forward packets with the source MAC address as the blackhole MAC address.
