Port Security
Port Security Settings
A given port’s (or a range of ports') dynamic MAC address learning can be locked such that the current source MAC
addresses entered into the MAC address forwarding table cannot be changed once the port lock is enabled. The port
can be locked by changing the Admin State pull-down menu to Enabled and clicking Apply.
Port Security is a security feature that prevents unauthorized computers (with source MAC addresses) unknown to the
Switch prior to locking the port (or ports) from connecting to the Switch's locked ports and gaining access to the
network.
