segment. When that specific MAC address does not exist on the look-up table, the port is blocked to all
the devices.
An example of this is a researcher who has a number of LAN devices (a PC, a printer, a notebook,
testing equipment, etc.) hooked-up to a "local lab segment" connected to the organization's network
through manageable Mosaic switch secured access port. The researcher has assigned his notebook as
the approved address. When low security is enabled, all the devices on the lab segment cannot access
the network unless the researcher’s notebook is connected to the lab segment.
Another example is the company conference room that has a local segment. Visitors may plug into the
segment but it will stay isolated from the network unless a company authorized representative is
present and connected.
NOTE
: The Low Security Level blocks data transmission through the port after the aging
time of the approved address has elapsed. It is important to keep this in mind when
configuring the aging time parameters.
5.2.1.3 To Configure MAC Access Security
There are two modes of MAC security:
•
MAC Access Security is locally authenticated according to the approved MAC
•
The Approved MAC is authenticated by the Radius server before continuing with the
MAC Access Security process.
The MAC security mode is selected only through the Telnet application. See Section 8.5.
Set a locally approved MAC address as follows:
1. In the
Embedded web interface
main
screen, click on the required Port icon.
The
Port
View
window appears. Expand the
MAC Security
tab.
