Glossary
ARR Asynchronous Response Router. Refers to the Management Server
GS_Subtype Code E4, which appears in the command
portlogdump
output.
ASD Alias Server Daemon. Used for managing multicast groups by
supporting the create, add, remove, and destroy functions.
ASIC Application-specific integrated circuit.
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. See also Digital Certificate, Switch-to-Switch
Authentication.
AW_TOV Arbitration wait time-out value. The minimum time an arbitrating
L_Port waits for a response before beginning loop initialization.
B
Bandwidth
The total transmission capacity of a cable, link, or system. Usually
measured in bps (bits per second). May also refer to the range of
transmission frequencies available to a network. See also Throughput.
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
Buffer-to-Buffer Flow Control and EE_Credit.
Beacon When 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 the Telnet
command or through Web Tools.
Beginning Running The disparity at the transmitter or receiver when the special character
Disparity associated with an ordered set is encoded or decoded. See also
Disparity.
BER Bit error rate. The rate at which bits are expected to be received in
error. Expressed as the ratio of error bits to total bits transmitted. See
also Error.
