Port Security

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 can not be changed once the
port lock is enabled. Using the Admin State pull-down menu to Enabled, and clicking Apply can lock
the port.
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.
