Downloading the Autolearning Database
You must download the contents of the Autolearning database to the
Security Module ports in order for the MAC Addresses to be associated
with the ports. When Autolearning Capture is complete, download the
Autolearning database to initiate port security. Depending on the amount
of network traffic transmitted to the Security Module ports, you may elect
to defer the Autolearn download for a day, several days, or a week.
Waiting to download the captured MAC addresses allows all of a port's
associated MAC addresses to be entered into the Autolearning database.
The Autolearning database for an EMM can contain a maximum of 360
MAC addresses. The Autolearning database for a TRMM can contain a
maximum of 400 MAC addresses.
Since a maximum of four MAC addresses can be associated with one port,
only four MAC addresses are downloaded. The four MAC addresses with
the lowest alpha-numerical values are downloaded from the Autolearning
database to a Security Module ports.
Issue the following command to download the Autolearning database to
port 1 on the Security Module in slot 3.
ONline> set security autolearn 3.1 download [ENTER]
If MAC addresses for the specified port currently exists in the port MAC
address table, the following message is displayed when the Autolearn
Download command is issued:
Note: overwriting existing addresses in the Security database.
The following message is displayed upon completion of the Autolearn
Download command (where y indicates the total number of addresses
copied to the port's MAC address table):
Autolearn download done; downloaded y addresses total.
If a port has more than four MAC addresses in the Autolearning database
at the time of the download, the following message displays upon
completion of the Autolearn Download command:
