Sequence Single mode SNMP SNS Switch Switch Domain_ID Switch name SWL Target Topology Translative mode Transmission character Transmission word Trap (SNMP) A fibre channel structure containing one or more frames transmitted in a unidirectional manner between N_Ports. See also Exchange, Frame. Fibre-optic cabling standard that provides for distances of up to 10 km between devices. Simple Network Management Protocol. Internet management protocol that does not rely on underlying communication protocols and can therefore be made available over other protocols, such as UDP/IP. See also Community (SNMP). Simple Name Server. See Name server. A combination of hardware and firmware that routes frames according to fibre channel protocol. Switches can have G_Ports, E_Ports, F_Ports, and FL_Ports. Unique identifier for a switch, used in routing frames. Usually automatically assigned by the switch, but can be manually assigned by administrator. Arbitrary name assigned to switch by administrator. See also Switch Domain_ID. Short wavelength fiber-optic cable. Based on 850-nm lasers supporting 1.0625-Gbps link speeds. Connectors are color-coded black. See also LWL. Storage device that receives communications from a server or workstation over a fibre channel network. See also Initiator. As applies to fibre channel, the structure of the fibre channel network and the resulting possible communication paths. There are three fibre channel topologies: point-to-point, fabric, and arbitrated loop. Mode in which public devices can communicate with private devices across fabric. A 10-bit character encoded according to the rules of the 8b/10b algorithm. See also 8b/10b encoding, Transmission word. Group of 4 transmission characters, totaling 40 bits. Two types: data words and ordered sets. See also Data word, Ordered set, Transmission character. Message sent by SNMP agent to inform SNMP management station of critical error. See also SNMP. 50 QuickLoop User's Guide
