Configuring the Limited Security Mode
The Limited security mode lets you set the maximum number of
dynamic MAC addresses each port on a switch can learn. When you
activate this security level, the switch deletes all MAC addresses in the
dynamic MAC address table and immediately begins to learn new
addresses as frames are received on the ports. Once the maximum
number of MAC addresses have been learned by a port, ingress frames
with new source MAC addresses received on the port are discarded and
are not forwarded.
You can assign the same limit to all ports or different limits to different
ports.
Static MAC addresses are not deleted from the static MAC address table.
Static MAC addresses are not included in the count of the maximum
MAC addresses a port can learn. You can continue to add static MAC
addresses even after a port has learned its maximum number of dynamic
MAC addresses.
To configure Limited security mode, perform the following procedure:
1. From the Main Menu, type 1 to select Port Menu.
2. From the Port Menu, type 5 to select Port Security.
The Port Security menu is shown in Figure 18 on page 79.
3. From the Port Security menu, type 2 to select Configure Limited
Mode Parameters.
