The MAC addresses can be dynamically learned, up to that point, or they can be statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet's source MAC address is not tied to that port (either it was learned on a different port, or is unknown to the system), the protection mechanism is invoked, and can provide various options. Unauthorized packets arriving to a locked port are either: • Forwarded • Discarded with no trap • Discarded with a trap • The ingress port is disabled Configuring Device Information 209
