address is not tied to that port (either it was learned on a different port, or it is
unknown to the system), the protection mechanism is invoked, and can provide
various options. Unauthorized packets arriving at a locked port are either:
• Forwarded
• Discarded with no trap
• Discarded with a trap
• Cause the port to be shut down.
Locked port security also enables storing a list of MAC addresses in the
configuration file. The MAC address list can be restored after the device has been
reset. Disabled ports are activated from the Port Security Page.
NOTE To configure port lock, 802.1x multiple host mode must be enabled.
