arbitration A method of gaining orderly access to a shared-loop topology.
area number In Fabric OS 4.0 and later, ports on a switch are assigned a logical area
number. These area numbers can be viewed by entering the switchShow
command. They are used to define the operative port for many Fabric OS
commands; for example, area numbers can be used to define the ports within
an alias or zone.
ARP Address Resolution Protocol. A TCP/IP function for associating an IP address
with a link-level address.
ARR Asynchronous response router. A term that refers to Management Server
GS_Subtype Code E4, which appears in portLogDump command output.
ASD Alias server daemon. Used for managing multicast groups by supporting the
create, add, remove, and destroy functions.
ASIC Application-specific integrated circuit. A chip designed for a particular
application, as contrasted with integrated circuits that control general functions,
such as RAM in a PC.
ATM Asynchronous Transfer Mode. A transport used for transmitting data over
LANs or WANs that transmit fixed-length units of data. Provides any-to-any
connectivity and allows nodes to transmit simultaneously.
authentication The process of verifying that an entity in a fabric (such as a switch) is what it
claims to be.

autocommit A feature of the firmwareDownload command. Enabled by default,
autocommit commits new firmware to both partitions of a control processor.
autoreboot Refers to the -b option of thefirmwareDownload command. Enabled by
default.
AW_TOV Arbitration wait timeout value. The minimum time an arbitrating L_Port waits
for a response before beginning loop initialization.
backbone fabric An optional capability that enables scalable meta-SANs by allowing the
networking of multiple Fibre Channel (FC) routers, which connect to the
backbone fabric via EB_Port interfaces.
backup FCS Relates to the Secure Fabric OS feature. The backup fabric configuration server
switch serves as a backup in case the primary FCS switch fails.

BB_Credit Buffer-to-buffer credit. The number of frames that can be transmitted to a directly
connected recipient or within an arbitrated loop. Determined by the number
of receive buffers available.
See also
BB fabric A backbone fabric that connects MP Routers. The MP Routers communicate over
the backbone fabric using FCRP (Fibre Channel Router Protocol).
beacon An activity in which all the port LEDs on a switch are set to flash from one side
of the switch to the other, to enable identification of an individual switch in a
large fabric. A switch can be set to beacon by a CLI command or through HP
Advanced Web Tools.
beginning running The disparity at the transmitter or receiver when the special character associated
disparity with an ordered set is encoded or decoded.
