Glossary
Fx_Port
A fabric port that can operate as either an F_Port or FL_Port.
G_Port
Generic Port; a port that can operate as either an E_Port or F_Port. A port is defined as a
G_Port when it is not yet connected or has not yet assumed a specific function in the fabric.
Gateway
A device such as a switch that connects different subnets together. A switch can be used as a gateway from the Ethernet to the Fibre Channel. Set the gateway address on one switch to the Fibre Channel IP address of another switch to enable the other switch to forward IP traffic to the ethernet port on the second switch.
Gbps
Gigabits per second (1,062,500,000 bits/second).
GBps
GigaBytes per second (1,062,500,000 bytes/second).
HBA
Host Bus Adapter; the interface card between a server or workstation bus and the Fibre Channel network.
Hub
A Fibre Channel wiring concentrator that collapses a loop topology into a physical star topology. Nodes are automatically added to the loop when active and removed when inactive.
Idle
Continuous transmission of an ordered set over a Fibre Channel link when no data is being transmitted, to keep the link active and maintain bit, byte, and word synchronization.
ISL
Interswitch Link; a Fibre Channel link from the E_Port of one switch to the E_Port of another. See also E_Port, Cascade.
Isolated E_Port
An E_Port that is online but not operational due to overlapping domain IDs or nonidentical parameters (such as E_D_TOVs).
IU
Information Unit; a set of information as defined by either
