SNMP
Simple Network Management Protocol. An Internet management protocol that uses either IP for
network-level functions and UDP for transport-level functions, or TCP/IP for both. Can be made available
over other protocols, such as UDP/IP, because it does not rely on the underlying communication protocols.
See also community (SNMP).
switch name
The arbitrary name assigned to a switch.
switch port
A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports. See also E_Port, F_Port, FL_Port.
syslog
Syslog daemon. Used to forward error messages.
T11
A standards committee chartered with creating standards for Fibre Channel.
target
A storage device on a Fibre Channel network. See also initiator.
TCP/IP
Transmission Control Protocol Internet Protocol. A communications protocol developed under contract from
the U.S. Department of Defense to internetwork dissimilar systems.
telnet
A virtual terminal emulation used with TCP/IP. Telnet is sometimes used as a synonym for the HP
StorageWorks 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: A direct link between two communication ports.
• Switched fabric: Multiple N_Ports linked to a switch by F_Ports.
• Arbitrated loop: Multiple NL_Ports connected in a loop.
translate domain
A router virtual domain that represents an entire fabric. Device connectivity can be achieved from one
fabric to another, over the router and through this virtual domain, without merging the two fabrics. Also
known as phantom domains.
trap (SNMP)
The message sent by an SNMP agent to inform the SNMP management station of a critical error. See also
SNMP.
trunking
In Fibre Channel technology, a feature that enables distribution of traffic over the combined bandwidth of
up to four ISLs between adjacent switches, while preserving in-order delivery.
tunneling
A technique for enabling two networks to communicate when the source and destination hosts are both on
the same type of network but are connected by a different type of network.
