4.13 Port Security
(To be Continued)
Port security is a feature that allows you to configure a switch port with one or more device MAC addresses that are authorized
to access the network through that port.
When port security is enabled on a port, the Managed Switch stops learning new MAC addresses on the specified port when it
has reached a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static
address table will be authorized to access the network through that port. If a device with an unauthorized MAC address attempts
to use the switch port, the intrusion will be detected and the switch can automatically take action by disabling the port and
sending a trap message.
<source MAC address, VLAN> pair for frames received on the port.
Note that you can also manually add secure addresses to the port using the Static Address Table. The selected port will stop
learning. 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 Table Learning

The page includes the following fields:
Object Description
• Auto
Learning is done automatically as soon as a frame with unknown SMAC is
received.
• Disable
No learning is done.
• Secure
Only static MAC entries are learned, all other frames are dropped.
