Technical data

229
Single mode Fibre-optic cabling standard that provides for distances of up to 10 kilometers
between devices.
SNMP 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. Uses IP for network
layer functions and UDP for transport layer functions, or TCP/IP for both.
See also Community (SNMP).
SNMPv1 The original standard for SNMP, now labeled v1.
SNS Simple Name Server. See Name server.
Switch 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.
Switch Domain_ID Unique identifier for a switch, used in routing frames. Usually automatically
assigned by the switch, but can be manually assigned by administrator.
Switch name Arbitrary name assigned to switch by administrator. See also Switch
Domain_ID.
Switch Port Port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
SWL Short wavelength fiber-optic cable. Based on 850-nm lasers supporting
1.0625-Gbps link speeds. Connectors are color-coded black. See also LWL.
Target Storage device that receives communications from a server or workstation
over a fibre channel network. See also Initiator.
Tenancy The time from when a port wins arbitration in a loop until the same port
returns to the monitoring state. Also referred to as loop tenancy.
Throughput The rate of data flow achieved within a cable, link, or system. See also
Bandwidth.
Topology 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.
Transfer State A state in which a port can establish circuits with multiple ports without
reentering the arbitration cycle for each circuit. This state can only be
accessed by an L_Port in the Open state.
