The following list defines or identifies technical terms, abbreviations, and acronyms used in Dell™ user documents. A fabric software facility that supports multicast group management. The FC Arbitrated Loop (FC-AL) is a standard defined on top of the FC-PH standard. It defines the arbitration on a loop where several FC nodes share a common medium. In Class 2 service, the fabric and destination N_Port provide connectionless service with notification of delivery or nondelivery between the two N_Ports. Class 3 service provides connectionless service without notification of delivery between N_Ports. The transmission and routing of Class 3 frames is the same as for Class 2 frames. A class of service used for interswitch control traffic. It provides connectionless service with notification of delivery or nondelivery between two E_Ports. An SNMP community is a relationship between an SNMP agent and a set of SNMP managers that defines authentication, access control, and proxy characteristics. Credit, applied to a switch, is a numeric value that represents the maximum number of receive buffers provided by an F_Port or FL_Port to its attached N_Port or NL_Port respectively such that the N_Port or NL_Port may transmit frames without overrunning the F_Port or NL_Port. The domain number uniquely identifies the switch in a fabric. This switch domain ID is normally automatically assigned by the switch and may be any value between 0 and 31. This number may also be assigned manually. E_D_TOV (Error-Detect Time-Out Value) defines the time the switch waits for an expected response before declaring an error condition. The error detect time out value is adjustable in 1 ms increments from two seconds up to 10 seconds. A port is designated an E_Port when it is used as an interswitch expansion port to connect to the E_Port of another switch to build a larger switch fabric. The name applied to a network resulting from the interconnection of switches and devices by interswitch links (ISLs). A fabric is an active, intelligent, nonshared interconnect scheme for nodes. support.dell.com Glossary 1
