The Port Addressing menu allows you to set up security and to add static MAC addresses to a port. When
entering this option, you must first identify a port to configure, as listed in Table 15.2.
Table 15.2: The available configurable ports on a Catalyst 2820 from the Port Addressing menu.

When the port is a secured port, its MAC address will be 00−00−00−00−00−00. The following is the list of
options and parameters for the Port Addressing menu:
[T] Address table size—Defines the number of allowable MAC addresses if the port is secure port
enabled. The range can be any value from 1 to 132. The default is 132; it cannot be changed if the
port is not secure port enabled.
•
[S] Addressing security—Allows you to enable or disable secure port, which is also known as
addressing security.
•
[U] Flood unknown unicast—Allows you to enable or disable flooding of unknown unicasts out all
the ports.
•
[M] Flood unregistered multicast—Allows you to enable or disable flooding unregistered multicasts
out all the ports.
•
[A] Add a static address—Allows you to add a static unicast hexadecimal MAC address to the table,
if the table is not full.
•
[D] Define restricted static address—Allows a source MAC address to be identified, thereby
allowing only the device using that MAC address to use the port.
•
[L] List addresses—Displays all the static and dynamic MAC addresses that the switch has learned
are attached to the port. The screen displays the first 15 entries beginning with those that have been
statically configured.
•
[E] Erase an address—Allows you to remove a statically or dynamically configured MAC address
associated with the port.
•
[R] Remove all addresses—Allows you to remove all statically or dynamically configured MAC
address associated with the port.
