Glossary PKI Public key infrastructure. An infrastructure that is based on public key cryptography and CA (certificate authority) and that uses digital certificates. See also digital certificate and public key cryptography. PKI certification utility Public key infrastructure certification utility. A utility that makes it possible to collect certificate requests from switches and to load certificates to switches. See also digital certificate and PKI. PLDA Private loop direct-attached. A technical report specifying a logical loop. PLOGI Port login. The port-to-port login process by which initiators establish sessions with targets. See also FLOGI. POD See Ports on Demand. point-to-point A Fibre Channel topology that employs direct links between each pair of communicating entities. See also topology. port In a Brocade SilkWorm switch environment, an SFP or GBIC receptacle on a switch to which an optic cable for another device is attached. port address In Fibre Channel technology, the port address is defined in hexadecimal. In the Brocade Fabric OS, a port address can be defined by a domain and port number combination or by area number. In an ESCON Director, an address used to specify port connectivity parameters and to assign link addresses for attached channels and control units. port-based routing A routing policy in which the choice of routing path is based on the incoming port and the destination domain. To optimize port-based routing, the Dynamic Load Sharing feature (DLS) can be enabled to balance the load across the available output ports within a domain. See also device-based routing and exchange-based routing. port cage The metal casing extending out of the optical port on the switch, into which the SFP can be inserted. port card A hardware component that provides a platform for field-replaceable, hot-swappable ports. port group A group of adjacent ports that share a common pool of frame buffers for long distance connections. port-level Defines a zone member by "domain,port", which is the physical port to which the member is connected. zoning See also zone member and WWN-level zoning. port mirroring Lets you configure a switch port as an analyzer port to mirror specific source and destination port traffic passing though any switch port, in other words, it enables non-disruptive traffic analysis. Port mirroring is supported between VE_ports (VE_Port to VE_Port) with FCIP and no routing, and over VEX _Ports and EX_Ports. The mirror port can be any port located on the same switch as the source identifier (SID). port name A user-defined alphanumeric name for a port. port swapping A feature that enables you to swap the area numbers for a pair of ports on a switch or director. If a device that uses port binding is connected to a port that fails, you can use port swapping to make another physical port use the same PID as the failed port. The device can then be plugged into the new port without the need to reboot the device. 24 Brocade Glossary Publication Number: 53-1000040-03
