Authorized
Addresses
Appears when Learn Mode is set to Static. Enables you to enter up to eight authorized devices (MAC
addresses) per port, depending on the value specified in the Address Limits field. If you enter fewer devices
than you specified in the Address Limits field, the port learns the remaining addresses from the inbound
traffic it receives. For example, if you specify four devices, but enter only two MAC addresses, the first two
(non-specified) devices subsequently detected on the port will be added to the Authorized Address list, and
all subsequent (non-specified) devices detected on the port will be handled as “unauthorized”.
Caution: If you enter fewer devices (MAC addresses) than specified in the Address Limits parameter, it is
possible to unintentionally allow a device to become “authorized” that you do not want to include in your
Authorized Address list. This can occur because the port, in order to fulfill the number of devices allowed
by the Address Limits parameter, will automatically add devices it detects until the specified limit is reached.
For this reason it is recommended that you configure the Address Limit to allow only as many devices as
you plan to type in to the Authorized Addresses list.
