Command Usage
• If you enable port security, the 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 accepted.
• First use the port security max-mac-count command to set the
number of addresses, and then use the port security command to
enable security on the port.
• Use the no port security max-mac-count command to disable port
security and reset the maximum number of addresses to the default.
