Brocade

A Brocade product that runs on Fabric OS and allows partitioning of the fabric

ZoningTM

into logical groupings of devices. Devices in a zone can only access and be

 

accessed by devices in the same zone. See also Zone.

Buffer-to-bufferManagement of the frame transmission rate in either a point-to-point topology or Flow Control in an arbitrated loop. See also BB_Credit.

Cascade

Two or more interconnected fibre channel switches. SilkWorm 2000 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.

Chassis

The metal frame in which the switch and switch components are mounted.

Circuit

An established communication path between two ports. Consists of two virtual

 

circuits capable of transmitting in opposite directions. See also Link.

Class 1

Service that provides a dedicated connection between two ports (also called

 

connection-oriented service), with notification of delivery or nondelivery.

Class 2

Service that provides multiplex and connectionless frame switching service

 

between two ports, with notification of delivery or nondelivery.

Class 3

Service that provides a connectionless frame switching service between two ports,

 

without notification of delivery or nondelivery of data. Can also be used to

 

provide a multicast connection between the originator and recipients, with

 

notification of delivery or nondelivery.

Class F

Class of

Service

Comma

Community (SNMP)

Connectionless service for control traffic between switches, with notification of delivery or nondelivery of data between the E_Ports.

A specified set of delivery characteristics and attributes for frame delivery.

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.

CRC

Cyclic Redundancy Check; a check for transmission errors included in every data

 

frame.

Credit

As applies to fibre channel, the number of receive buffers available for

 

transmission of frames between ports. See also BB_Credit, EE_Credit.

Cut-through

A switching technique that allows the route for a frame to be selected as soon as

 

the destination address is received. See also Route.

Data Word

Type of transmission word that occurs within frames. The frame header, data

 

field, and CRC all consist of data words. See also Frame, Ordered set,

 

Transmission Word.

Defined Zone Configuration

Disparity

The set of all zone objects defined in the fabric. May include multiple zone configurations. See also Enabled Configuration, Zone Configuration.

The relationship of ones and zeros in an encoded character. “Neutral disparity” means an equal number of each, “positive disparity” means a majority of ones, and “negative disparity” means a majority of zeros.

DLS

Dynamic Load Sharing; dynamic distribution of traffic over available paths.

 

Allows for recomputing of routes when an Fx_Port or E_Port changes status.
