Configuring Port Security

Use the Port Security page to lock the address table for specified ports. If
you enable port security, the switch will stop learning new addresses on the
specified port. Only incoming traffic with source addresses already stored
in the dynamic address table will be accepted. The MAC addresses already
in the address table will be retained and will not age out. This can be used
to prevent unauthorized access to the switch.
To use port security, first allow the switch to dynamically learn the source
MAC address for frames received on an interface for an initial training
period, and then enable port security to stop address learning. Be sure you
enable the learning function long enough to ensure that all valid members
have been registered on the selected interface.
To add new members at a later time, you can manually add static addresses,
or turn off port security to reenable the learning function long enough for
new members to be registered. Learning may then be disabled again, if
desired, for security.
Console – Click Switch Static Configuration=>Misc Configuration=>Port
Security. Enable security on the required ports, then save your settings.
