Ethernet Port Configuration: Port Security
TABLE
DESCRIPTION
Active
Select this check box to enable the port security feature on selected ports.
Address Learning MAC address learning reduces outgoing broadcast traffic. For MAC address
learning to occur on a port, the port itself must be active with address learning
enabled. Select the
Address Learning
check box.
Limited Number
of Learned MAC
Address
Use this field to limit the number of (dynamic) MAC addresses that may be learned
on a port. For example, if you set this field to "5" on port 2, then only the devices
with these five learned MAC addresses may access port 2 at any one time. A sixth
device would have to wait until one of the five learned MAC addresses aged out.
MAC-address aging out time can be set in the
Switch Setup
screen. The valid
range is from 0 to 16K. 0 means this feature is disabled, so the switch will learn
MAC addresses up to the global limit of 16K.
MAC Freeze
Click
MAC Freeze
to convert all current dynamic MAC addresses to static MAC
addresses. When you click the
MAC Freeze
button, the
MAC
Address Learning
check box is cleared but port security becomes
Active
.
Apply
Click
Apply
to save the changes.
