Time Server A Fibre Channel service that allows for the management of all timers.
topology As it applies to 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.
TPC Third-party copy. A protocol for performing tape backups without using server resources.
track changes A Brocade 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.
transceiver A device that converts one form of signaling to another for transmission and reception; in fiber optics,
optical to electrical.
translate
domain
See xlate domain.
Translative
Mode
A mode in which private devices can communicate with public devices across the fabric.
transmission
character
A 10-bit character encoded according to the rules of the 8b/10b algorithm.
transmission
word
A group of four transmission characters.
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.
trunking group A set of up to four trunked ISLs.
trunking ports The ports in a set of trunked ISLs.
TS Time Server.
TTL Time-to-live. The number of seconds an entry exists in cache before it expires.
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.
TX Transmit.
