Glossary
P
Packet A set of information transmitted across a network. See also Frame.
Participating Mode A mode in which an L_Port in a loop has a valid AL_PA and can
arbitrate, send frames, and retransmit received transmissions. See
also L_Port and Nonparticipating Mode.
Path Selection The selection of a transmission path through the fabric. EMC switches
use the FSPF protocol.
PLOGI Port Login. The port-to-port login process by which initiators
establish sessions with targets. See also FLOGI.
Point-to-Point A Fibre Channel topology that employs direct links between each
pair of communicating entities. See also Topo log y.
Port_Name The unique identifier assigned to a Fibre Channel port.
Communicated during login and port discovery.
Port Cage The metal casing extending out of the optical port on the switch, and
in which the GBIC or SFP can be inserted.
Port Card A Fibre Channel card that contains optical port interfaces. See also
16-Port Card.
Port Module A collection of ports in a switch.
POST Power-on self test. A series of tests run by a switch after it is turned
on.
Principal Switch The switch that assumes the responsibility to assign Domain IDs. The
role of Principle Switch is negotiated after a Build Fabric event.
Primary FCS Switch Primary fabric configuration server switch. The switch that actively
manages the configuration and security parameters for all switches in
the fabric. See also Backup FCS Switch and FCS Switch.
Private Device A device that supports arbitrated loop protocol and can interpret
8-bit addresses, but cannot log in to the fabric.
Private Loop An arbitrated loop that does not include a participating FL_Port.
