Fabric port
The zone set that defines the current zoning for the fabric.
The firmware image on the switch that is in use.
A port LED that indicates when frames are entering or leaving the port.
State that determines the operating state of the port, I/O blade, or switch. The configured
administrative state is stored in the switch configuration. The configured administrative state
can be temporarily overridden using the Command Line Interface.
A message generated by the switch that specifically requests attention. Alarms are
generated by several switch processes. Some alarms can be configured.
Arbitrated Loop Physical Address
An FC topology where ports use arbitration to establish a point-to-point circuit.
A unique one-byte value assigned during loop initialization to each NL_Port on a loop.
Application Specific Integrated Circuit. A chip designed for a specific applications, such as
a transmission protocol or a computer.
Zoning parameter that determines whether changes to the active zone set that a switch
receives from other switches in the fabric will be saved to permanent memory on that switch.
Boot Strap Protocol. A type of network server.
A measure of port buffer capacity equal to one frame.
A fabric in which the switches are connected in series. If you connect the last switch back to
the first switch, you create a cascade-with-a-loop topology.
Challenge Handshake Authentication Protocol.
A service which multiplexes frames at frame boundaries to or from one or more N_Ports
with acknowledgment provided.
A service which multiplexes frames at frame boundaries to or from one or more N_Ports
without acknowledgment.
A measure of fabric latency represented by the ISL that any frame crosses when travelling
from one switch to another. A frame that travels from one switch to another over an ISL
experiences one chassis hop.
A component of fabric security that provides for the authorization and authentication of
devices that attach to a switch through the use of groups and security sets.
User defined number that identifies the switch in the fabric.
Enterprise Fabric Connectivity Manager
McDATA Element Manager. Switch management application that is accessible through the
High Availability Fabric Manager (HAFM).
Log of messages describing events that occur in the fabric.
E_Port that connects to another FC-SW-2 compliant switch.
The set of fabrics that have been opened during a McDATA Web Server session.
An interface by which device host bus adapters can be managed through the fabric.
The switch through which the fabric is managed (the switch connected to the Ethernet
network).
User defined name associated with the file that contains user list data for the fabric.
An F_Port or FL_Port.
