What is the difference between STP and Loop Protection?
The ProCurve 1810GG switch software is equipped with an automatic Loop Protection feature. Loop Protection is enabled and disabled globally and on a port-by-port basis. When enabled globally, the software sends loop protection packets to a reserved layer 2 multicast destination address on all the ports on which the feature is enabled. Transmission of the packet can be disabled selectively on certain ports, even when Loop Protection is enabled. If this multicast packet comes back to the switch with any of the ports’ MAC addresses as the source, the switch determines that a loop has occurred. The port that received the loop protection packet from the switch can be shut down for a configurable period, and a log entry can be made. Ports on which Loop Protection is disabled drop the loop protection packets silently. To configure Loop Protection, click Switching > Loop Protection in the navigation pane.
