In the regular bit addressing mode, the portaddress --auto command supports addresses from 0x00 to 0x8F. This means a logical switch can support up to ports that can each support devices. Hence these ports support only 64 NPIV devices per port. These events include login failures, zone configuration changes, firmware downloads, and other configuration changes—in other words—critical changes that have a serious effect on the operation and security of the switch.

It is also for those individuals who do not have the time to attend the formal training, but who still wish to be certified as a BCFP. This guide is for those who work with Brocade switches and are proficient in their knowledge of the features and functionality as well as the day-to-day operations of the Brocade Product Line.
It is not intended as a substitute for classroom training, and hands-on time. It is organized closely around the exam objectives. We hope you find this guide useful in your journey towards BCFP Certification, and we welcome your feedback. For example: v4. Translative mode allows a fabric server to access a private target In v3.
Link incidents are problems that occur on a link between a host or storage CU port and the switch port. All cladding sizes are ? Serial Port - DB-9 female-female cable , 8 data, 1 stop, no parity, no flow Telnet only 1 session active on any switch. A telnet overrides a serial connection in v2.
FDMI Fabric Device Management Interface support allows firmware downloads to Emulex HBAs Switch naming Monitor and manage port groupings Port level support Advanced license key management with e-licensing Enhanced discovery and subnet scanning Advanced topology views circular, hierarchical, core-to-edge Multiple at-a-glance views New detail and summary views Call home Fabric and zone merge checking 5.
Requires a license key Uses ports in the same quad 1 ISL will show as a trunk group if license installed Automatically enabled by default - switchcfgtrunk 0 to disable trunking switch-wide Creates one virtual fat ISL Trunking is at the frame level 5. Allows a private initiator to access a non-private target QuickLoop and Zoning licenses are required Supported in v2. An FA host cannot be on a QL enabled switch.
In v2. It should be run after each time the switch has had something change. A good supportshow can save a support department? Contents vary by firmware revision of the Fabric OS. After that, the timed test will begin. This is a sample of how the questions will look. In this example, you see a multiple-choice question. Figure Sample Question? Access fairness A process by which contending nodes are guaranteed access to an Arbitrated Loop. Access method The method used to access a physical medium in order to transmit data.
ACK Acknowledgement frame; used for end-to-end flow control; verifies receipt of one or more frames from Class 1,2 or F services. Active copper A Fibre Channel connection that allows copper cabling up to 33 meters 36 yards in length between devices.
Address identifier A bit number used to indicate the link-level address of communicating devices. The default value is 15 milliseconds ms. Arbitration A method of gaining orderly access to a shared-loop topology. It provides any-to-any connectivity and nodes can transmit simultaneously.
Bandwidth The transmission capacity of the cable, link, or system. Boot code Software that initialized the system environment during the early phase of the boot up process. For example, boot code may determine the amount of available memory and how to access it.
Boot flash Flash temporary memory that stores the boot code and boot parameters. Bypass circuitry Circuits that automatically remove a device from the data path when valid signals are dropped.
CAM Content addressable memory. Seven levels of cascading is the limit for Brocade switches. CDR Clock and data recovery circuitry. Channel A point-to-point link whose task is to transport data from one point to another.
CIM Common Information Model; a management structure enabling disparate resources to be managed by a common application. Class 1 A connection-oriented class of service that requires acknowledgment of frame delivery. Class 2 A connectionless class of service that requires acknowledgment of frame delivery.
Class 4 A connection-oriented service that allows fractional parts of the bandwidth to be used in a virtual circuit.
Class 6 A connection-oriented multicast service geared toward video broadcasts between a central server and clients. Compact flash Flash temporary memory that is used in a manner similar to hard disk storage. It is connected to a bridging component, which connects to the PCI bus of the processor. Congestion The realization of the potential of over subscription. A congested link is one on which multiple devices actually are contending for bandwidth.
Controller A computer module that interprets signals between a host and a peripheral device. The controller typically is part of the peripheral device. COS Class of service. Datagram A Class 3 Fibre Channel service that allows data to be sent quickly to devices attached to the Fabric, with no confirmation of receipt.
Disparity The relationship of 1s and 0s in an encoded character; positive disparity contains more 1s, negative disparity contains more 0s, neutral disparity contains an equal number of 1s and 0s. Allows more wavelengths to use the same fiber. EOF End of Frame; a group of ordered sets used to mark the end of a frame. They are composed of 1 or more related sequences and work either unior bi-directionally.
Fabric One or more Fibre Channel switches in some networked topology. Fabric port count The number of ports available for connection by nodes in a Fabric. Fabric topology The arrangement of switches that form a Fabric.
Fan-in The ratio of hosts to storage devices. Fan-out The ratio of storage devices to hosts. FC-0 Lowest layer on Fibre Channel transport; represents the physical media. FC-PH-2 Second-generation physical interface. FC-PH-3 Third-generation physical interface. Fiber A copper or glass physical medium for transmitting data. Fibre Channel A high-speed, serial, bi-directional, topology independent, multi-protocol, highly scalable interconnection between computers, peripherals, and networks.
The payload can be bytes, and the CRC is 4 bytes. Full duplex Concurrent transmission and reception of data on a link.
Gateway A device that connects incompatible networks by providing the necessary translation, both for hardware and software. Gbps Gigabits per second. GBps Gigabytes per second. Gigabit 1,,, bits per second. Hop count Hop count is the number of ISLs a frame must traverse to get from its source to its destination. Hot swappable A component that can be replaced while under power.
Hub A Fibre Channel wiring concentrator that collapses a loop topology into a physical star topology. A hub may automatically recognize an active node and inserts it into the loop. A node that is not functioning is automatically removed from the loop. IDID Insistent Domain ID - the same Domain ID assignment to a switch under all fabric events is guaranteed Idle An ordered set transmitted continuously over a link when no data is being transmitted to maintain an active link.
It helps maintain bit, byte, and word synchronization. In-band Transmission of management protocol over the Fibre Channel transport. Initiator A server or workstation on a Fibre Channel network that initiates transactions to tapes or disks. Integrated Fabric The Fabric created by connecting multiple SilkWorm switches with multiple ISL cables, and configuring the switches to handle traffic as a seamless group.
Intercabinet A specification for copper cabling that allows up to meter distances between cabinets. Intermix Allows any unused bandwidth in a Class 1 connection to be used by Class 2 or Class 3.
Inter-switch link See ISL. Intracabinet A specification for copper cabling that allows up to a meter foot distance within a single cabinet. IOD In Order Delivery; a parameter than when set, guarantees that frames get delivered in order, or they are dropped. Jitter A deviation in timing for a bit stream as it flows through a physical medium. Latency The period that a frame is held by a network device before it is forwarded. Link control facility A termination handling physical and logical control of the Fibre Channel link for each mode.
This allows loop members to determine their relative loop position.
