Active Select this check box to enable the port security feature on this port. The Switch forwards

packets whose MAC address(es) is in the MAC address table on this port. Packets with no

matching MAC address(es) are dropped.

Clear this check box to disable the port security feature. The Switch forwards all packets

on this port.

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.

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 “16384”. “0” means

this feature is disabled.

Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses

these changes if it is turned off or loses power, so use the Save link on the top navigation

panel to save your changes to the non-volatile memory when you are done configuring.

Cancel Click Cancel to begin configuring this screen afresh.
