TCP/IP
Transmission Control Protocol/Internet Protocol.
telnet
A virtual terminal emulation used with TCP/IP. Telnet is sometimes used as a synonym for the HP Fabric OS
CLI.
topology
In Fibre Channel technology, the configuration of the Fibre Channel network and the resulting
communication paths allowed. There are three possible topologies:
• Point to point, which is a direct link between two communication ports.
• Switched fabric, in which multiple N_Ports are linked to a switch by F_Ports.
• Arbitrated loop, in which multiple NL_Ports are connected in a loop.
track changes
An HP Fabric OS feature that can be enabled to report specific activities (for example, logins, logouts, and
configuration task changes). The output from the track-changes feature is dumped to the error log for the
switch.
trap (SNMP)
The message sent by an SNMP agent to inform the SNMP management station of a critical error. See also
SNMP.
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.
UDP
User Datagram Protocol. A protocol that runs on top of IP and provides port multiplexing for upper-level
protocols.
well-known address
In Fibre Channel technology, a logical address defined by Fibre Channel standards as assigned to a
specific function and stored on the switch.
WWN
World Wide Name. An identifier that is unique worldwide. Each entity in a fabric has a separate WWN.
zone
A set of devices and hosts attached to the same fabric and configured as being in the same zone. Devices
and hosts within the same zone have access to others in the zone, but are not visible to any outside the
zone.
zoning
A feature in fabric switches or hubs that allows segmentation of a node by physical port, name, or address.
