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
drop-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.
