CMT comma community (SNMP) compact flash configuration congestion connection initiator connection recipient core PID COS CP CPLD CRC credit CSCN cut-through DAS Central memory test. A unique pattern (either 1100000 or 0011111) used in 8b/10b encoding to specify character alignment within a data stream. See also K28.5. A relationship between a group of SNMP managers and an SNMP agent, in which authentication, access control, and proxy characteristics are defined. See also SNMP. Flash (temporary) memory that is used in a manner similar to hard disk storage. It is connected to a bridging component that connects to the PCI bus of the processor. Not visible within the processor's memory space. (1) The number, type, and arrangement of components that make up a system or network. (2) The set of parameters that guide switch operation. May include general system parameters, IP address information, domain ID, and other information. Modifiable by any login with administrative privileges. Use the configShow command to view the current configuration of a switch. (3) 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. A condition that occurs when the offered load for a data communication path exceeds its capacity. For example, a congested link is one on which multiple devices are contending for bandwidth. A port that has originated a Class 1 dedicated connection and received a response from the recipient. A port that has received a Class 1 dedicated connection request and transmitted a response to the originator. Core switch port identifier. The core PID must be set for Fabric OS 3.1 and earlier switches included in a fabric of Fabric OS 4.1 switches. This parameter is located in the configure command of Fabric OS 3.1 and earlier firmware. All Fabric OS 4.1 switches and later use the core PID format by default; this parameter is not present in the configure command for these switches. See also PID. See Class of service. Control processor. Complex PLD. Also called Enhanced PLD (EPLD, Super PAL, and Mega PAL. See also PLD. Cyclic redundancy check. A check for transmission errors that is included in every data frame. As it applies to Fibre Channel technology, the number of receive buffers available to transmit frames between ports. See also BB_Credit, EE_Credit. Common services connection framework. A switching technique that allows the route for a frame to be selected as soon as the destination address is received. See also route. Direct attached storage. Fabric OS 5.x master glossary 7
