configuration (1) A set of parameters that can be modified to fine-tune the operation of a switch. Use the configShow command to view the current configuration of your switch. 2) In HP Zoning, a zoning element that contains a set of zones. The Configuration is the highest-level zoning element and is used to enable or disable a set of zones on the fabric. See also zone configuration. congestion The realization of the potential of oversubscription. A congested link is one on which multiple devices are contending for bandwidth. connection initiator A port that has originated a Class 1 dedicated connection and received a response from the recipient. connection recipient A port that has received a Class 1 dedicated connection request and transmitted a response to the originator. controller A computer module that interprets signals between a host and a peripheral device. The controller typically is part of the peripheral device. COS Class of service. CP Control processor. CRC Cyclic redundancy check. A transmission error check that is included in every data frame. credit As it applies to Fibre Channel technology, the number of receive buffers available to transmit frames between ports. See also BB_Credit, EE_Credit. cut-through A switching technique that allows the route for a frame to be selected as soon as the destination address is received. See also route. D_ID Destination identifier. A 3-byte field in the frame header, used to indicate the address identifier of the N_Port to which the frame is headed. DAS Direct attached storage. data word A type of transmission word that occurs within frames. The frame header, data field, and CRC all consist of data words. See also frame, ordered set, transmission word. DCC Direct cable connection. DCC does not require network interface cards (NICs), making it relatively inexpensive and simple; however, it provides a limited connection between two PCs, and the data transfer rate is slower than with a true LAN. dedicated simplex A connection method that permits a single N_Port to simultaneously initiate a session with one N_Port as an initiator and have a separate Class 1 connection to another N_Port as a recipient. defined zone configuration The set of all zone objects defined in the fabric. Can include multiple zone configurations. See also enabled zone configuration, zone configuration. deskew Related to the HP Trunking feature. The time difference between traffic traveling over each ISL other than the shortest ISL in the group and traffic traveling over that shortest ISL. The deskew number corresponds to nanoseconds divided by 10. The firmware automatically sets the minimum deskew value of the shortest ISL to 15. DHCP Dynamic Host Configuration Protocol. DHCPD Dynamic Host Configuration Protocol daemon. 800 Glossary
