TX
Transmit. See also RX.
Typical zoning 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
Custom
U
U_Port
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.
UDP
User Datagram Protocol. A protocol that runs on top of IP and provides port multiplexing for upper-
level protocols.
ULP Upper-level protocol. The protocol that runs on top of Fibre Channel. Typical upper-level protocols are
SCSI, IP, HIPPI, and IPI.
ULP_TOV
Upper-level timeout value. The minimum time that an SCSI ULP process waits for SCSI status before
initiating ULP recovery.
unicast
The transmission of data from a single source to a single destination. See also
upfront login 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.
UTC 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 format defined by the SilkWorm 1000 series. Connections to these switches are not supported in
PID Fabric OS v4.0.0 and later. See also
VE_Port
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
VEX_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.
