Glossary-2
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 telnet command or through Brocade Web Tools.
The disparity at the transmitter or receiver when the special character associated
with an ordered set is encoded or decoded. See also disparity.
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.
A two way connector used in some SilkWorm switches to provide a connection
between the motherboard and the power supply.
As applies to Fibre Channel, upper-level application data that is transferred in a
single sequence.
The transmission of data from a single source to all devices in the fabric,
regardless of zoning. See also multicast, unicast.
to buffer
- - Management of the frame transmission rate in either a point-to-point topology or
in an arbitrated loop. See also BB_Credit.
Two or more interconnected Fibre Channel switches. SilkWorm 2000 and later
switches can be cascaded up to 239 switches, with a recommended maximum of
seven interswitch links (no path longer than eight switches). See also fabric, ISL.
The metal frame in which the switch and switch components are mounted.
An established communication path between two ports. Consists of two virtual
circuits capable of transmitting in opposite directions. See also link.
The class of frame switching service for a dedicated connection between two
communicating ports (also called connection-oriented service), with
acknowledgement of delivery or nondelivery of frames.
A connectionless class of frame switching service that includes acknowledgement
of delivery or nondelivery of frames.
A connectionless class of frame switching service that does not include
acknowledgement of delivery or nondelivery of frames. Can be used to provide a
multicast connection between the frame originator and recipients, with
acknowledgement of delivery or nondelivery of frames.
The class of frame switching service for a direct connection between two
switches, allowing communication of control traffic between the E_Ports, with
notification of delivery or nondelivery of data.
A specified set of delivery characteristics and attributes for frame delivery.
Command line interface. Interface that depends entirely on the use of commands,
such as through telnet or SNMP, and does not involve a GUI.
A unique pattern (either 1100000 or 0011111) used in 8B/10B encoding to
specify character alignment within a data stream. See also K28.5.
A relationship between a group of SNMP managers and an SNMP agent, in which
authentication, access control, and proxy characteristics are defined. See also
SNMP.
