Field Attributes
• Port - The front-panel port-number of the port. This cannot be changed.
• Allowed number of Learned MAC addresses - Set the maximum of MAC
addresses that can be learned by this port. The Mode settings for the port are set
by a single drop-down list.
• No Limit - No limitation on the number of dynamcally learned MAC address.
This means port security is disabled.
• 8/7/6/5/4/3/2/1 - The maximum number of dynamically learned MAC address.
• 0 - No dynamically learned MAC address is allowed on this port. This does not
affect any static MAC addresses that are configured for the port.
Note:
Port security only handles dynamically learned MAC addresses and has no
limitations on static MAC addresses. On this switch, 24 static MAC address can be
configured by System > Static MAC.
Note: The MAC addresses already in the address table will be retained and will not age
out. Any other device that attempts to use the port will be prevented from
accessing the switch.

MAC addresses. The string ‘-’ is displayed if a port is set with “No Limit” mode in
the Allowed number of Learned MAC addresses field.
• Intrusion Action - Action to be carried out if unauthorized MAC addresses are
detected.
• Deny New Stations - The station with unauthorized MAC address will be denied
to access the port.
• Send Trap and Deny New Stations - Besides denying the new station, a trap
message is sent by the switch to report an intrusion action.
