Glossary TX Typical zoning Transmit. See also RX. In EZSwitchSetup, an option that provides predefined zoning on the switch and supports single-switch fabrics only (appropriate for less experienced SAN administrators). See also Advanced zoning and Custom zoning. U U_Port UDP ULP ULP_TOV unicast upfront login UTC Universal port. A switch port that can operate as a G_Port, E_Port, F_Port, or FL_Port. A port is defined as a U_Port when it is not connected or has not yet assumed a specific function in the fabric. Selection of the actual port type is automatic. User Datagram Protocol. A protocol that runs on top of IP and provides port multiplexing for upperlevel protocols. Upper-level protocol. The protocol that runs on top of Fibre Channel. Typical upper-level protocols are SCSI, IP, HIPPI, and IPI. Upper-level timeout value. The minimum time that an SCSI ULP process waits for SCSI status before initiating ULP recovery. The transmission of data from a single source to a single destination. See also broadcast and multicast. A login configuration setting for Web Tools. If upfront login is enabled, users log in only once, when they launch Switch Explorer. If upfront login is disabled (default), you can launch Switch Explorer without logging in, but you must log in every time you launch a switch administration module. Universal Time Conversion. Also known as "Coordinated Universal Time," which is an international standard of time. UTC is 8 hours behind Pacific Standard Time and 5 hours behind Eastern Standard Time. See also GMT. V VC Encoded PID VE_Port VEX_Port PID format defined by the SilkWorm 1000 series. Connections to these switches are not supported in Fabric OS v4.0.0 and later. See also native PID, core PID, and extended edge PID. Virtual E_Ports function somewhat like E_Ports, but terminate at the switch and do not propagate fabric services or routing topology information from one edge fabric to another. The link between an E_Port and an EX_Port or VE_Port is called an interfabric link (IFL). After you configure the VE_Ports on either two SilkWorm 7500s or two FR4-18i blades, an FCIP connection is established between them. See also FCIP Tunneling Service and GbE port. A type of VE_Port that connects an FC router to an edge fabric. From the point of view of a switch in an edge fabric, an VEX_Port appears as a normal VE_Port. It follows the same Fibre Channel protocol as other VE_Ports. However, the router terminates VEX_Ports rather than allowing different fabrics to merge as would happen on a switch with regular VE_Ports. Brocade Glossary 33 Publication Number: 53-1000040-03
