Which statement about the default action of MAC limiting is true when the number of...

According to the Juniper documentation 1 , MAC limiting is a feature that enhances port security by limiting the number of MAC addresses that can be learned within a VLAN. When the MAC limit is exceeded, the switch can perform different actions, such as ignoring, dropping, logging, shutting down, or disabling the offending port.  The default action is to drop the packets with new MAC addresses and log a message 2 . Therefore, the correct answer is B.

The other options are not correct because:

A. The switch will not shut down the offending port for five minutes by default.  This is a configurable action, but not the default one 2 .

C. The switch will not flood traffic out of all ports for the offending MAC address by default.  This is a possible consequence of ignoring the packets with new MAC addresses, but not the default action 2 .

D. The switch will not shut down MAC learning on the offending port for five minutes by default.  This is another configurable action, but not the default one 2 .
