Glossary network address Name or address that identifies a managed product on a transmission control protocol/internet protocol (TCP/IP) network. The network address can be either an IP address in dotted-decimal notation (containing four three-digit octets in the format xxx.xxx.xxx.xxx), or a domain name (as administered on a customer network). never principal The setting that prevents the product from becoming the principal switch for a fabric. nickname Alternate name assigned to a World Wide Name for a node or director in the fabric. node In Fibre Channel terminology, node refers to an end device (server or storage device) that is or can be connected to a switched fabric. node port (N_Port) - Physical interface within an end device that can connect to a fabric port (F_Port) on a switched fabric or directly to another N_Port (in point-to-point communications). node port identifier (N_Port ID) - In Fibre Channel protocol, a unique address identifier by which an N_Port is uniquely known. It consists of a domain (most significant byte), an area, and a port, each 1 byte long. The N_Port ID is used in the source identifier (S_ID) and destination identifier (D_ID) fields of a Fibre Channel frame. nondisruptive maintenance Ability to service FRUs (including maintenance, installation, removal and replacement) while normal operations continue without interruption. See also concurrent maintenance. N_Port See node port. offline sequence (OLS) - Sequence sent by the transmitting port to indicate that it is attempting to initialize a link and has detected a problem in doing so. offline state When the switch or director is in the offline state, all the installed ports are offline. The ports transmit an offline sequence (OLS) and they cannot accept a login connection from an attached device. See also online state. OLS See offline sequence. Directors and Edge Switches Glossary 19
