Port Security

Port Security Settings

A given ports' (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.
