Command Usage
• If you enable port security, the switch will stop dynamically learning new
addresses on the specified port. Only incoming traffic with source
addresses already stored in the dynamic or static address table will be
accepted.
• To use port security, first allow the switch to dynamically learn the
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 VLAN members have been registered on the selected port.
