The mode of operation in which a port is configured to operate may be selected so that the manner in which the port will interpret a loss of signal on a receive fiber may be specified. In an immediate mode, the port will interpret a loss of signal on a receive fiber as an indication of a fault on the transmit fiber (or interfaces associated with the transmit fiber) and will immediately shut its transmit interface down. In a multiple cycle detection mode, the port will not immediately interpret a loss of signal on a receive fiber as an indication of a fault on the transmit fiber, but rather will begin monitoring the receive fiber to look for a specified loss of signal pattern on the receive fiber. In this mode the port will interpret a repetitive loss of signal on the receive fiber as an indication of a fault on the transmit fiber. By providing a mode selector, the manner in which the ports are configured to operate may be adjusted individually, as a group, or globally. |
