K K28.5 KAT Key Key pair L L_Port LAN Latency LED Link control facility LIFA LIHA LILP Link Link control facility Link cost LIP LIPA A special 10-bit character used to indicate the beginning of a Fibre Channel ordered set. Known Answer Test. Used for encryption and decryption operations in FIPS compliance. See also FIPS (Federal Information Processing Standard). A string of data (usually a numeric value) shared between two entities and used to control a cryptographic algorithm. In public key cryptography, a pair of keys consisting of an entity's public and private key; the public key can be publicized, but the private key must be kept secret. Loop Port. A node port (NL_Port) or fabric port (FL_Port) that has arbitratedloop capabilities Local Area Network. A network where transmissions are typically less than 5 km (3.4 mi). The period that a frame is held by a network device before it is forwarded. Light Emitting Diode. A status indicator on a switch. A termination handling physical and logical control of the Fibre Channel link for each mode. Loop Initialization Fabric Assigned frame. Contains bitmap of all fabric assigned AL_PAs and is the first frame transmitted in the loop initialization process after a temporary loop master has been selected. Loop Initialization Hard Assigned frame. A hard assigned AL_PA that is indicated by a bit set and is the third frame transmitted in the loop initialization process after a temporary loop master has been selected. Loop Initialization Loop Position frame. The final frame transmitted in a loop initialization process. A returned LIRP contains an accumulation of all of the AL_PA position maps. This allows loop members to determine their relative loop position. This is an optional frame and is not transmitted unless the LIRP is also transmitted. A bi-directional point-to-point serial data channel. A termination, handling physical and logical control of the FC link for each node. A dimensionless positive number associated with the cost of an ISL or IFL that, by default, is inversely proportional to its bandwidth. Loop Initialization Primitive sequence. A means to get an AL_PA address, to indicate a loop failure or to reset a node. Loop Initialization Previously Assigned. A situation in which the device marks a bit in the bitmap if it had not logged in with the fabric in a previous loop initialization. Brocade SAN Glossary 1/29/2008 Page 15 of 29
