In-band method and apparatus for reporting operational statistics relative to the ports of a fibre channel switch

摘要

An in-band method/apparatus whereby a host is enabled to secure predetermined operational information relative to predetermined ports of a fiber channel switch. A set command is generated at the host and sent in-band to the switch. The information content of the set command defines the ports for which operational-parameters are to be monitored. The information content of the set command also defines which operational parameters are to be monitored. In response to receiving the set command, the switch establishes statistical counters for monitoring port operational parameters in accordance with received operational parameter identifiers. An accept signal is then sent in-band to the host, and a time period of port monitoring begins. After a predefined time period has expired, the host sends a read command in-band to the switch. The switch now generates a monitor record in accordance with the count content of the statistical counters that were established in response to the set command. This monitor record contains one port field for each of the ports that were specified by the set command, and each of the port fields contains one or more count fields that contain port operational count data for the port operational parameters that were specified by the set command. The monitor record is then sent in-band to the host. Recycling of the timed process may be provided.
