GLOSSARY 169

standby port	The port in a resilient link that takes over data transmission if the main
	port in the link fails.
STP	See Spanning Tree Protocol (STP).
switch	A device that interconnects several LANs to form a single logical LAN
	that comprises of several LAN segments. Switches are similar to
	bridges, in that they connect LANs of a different type; however they
	connect more LANs than a bridge and are generally more sophisticated.
Switch Database	See Forwarding Database.
TCP/IP	Transmission Control Protocol/Internet Protocol. This is the name for
	two of the most well-known protocols developed for the
	interconnection of networks. Originally a UNIX standard, TCP/IP is now
	supported on almost all platforms, and is the protocol of the Internet.
	TCP relates to the content of the data travelling through a network —
	ensuring that the information sent arrives in one piece when it reaches
	its destination. IP relates to the address of the endstation to which data
	is being sent, as well as the address of the destination network.
Telnet	A TCP/IP application protocol that provides a virtual terminal service,
	letting a user log into another computer system and access a device as
	if the user were connected directly to the device.
TFTP	Trivial File Transfer Protocol. Allows you to transfer files (such as
	software upgrades) from a remote device using the local management
	capabilities of the Switch.
traffic prioritization	A system which allows data that has been assigned a high priority to
	be forwarded through a switch without being obstructed by other data.
Transcend®	The 3Com umbrella management system used to manage all of 3Com’s
	networking solutions.
unicast	A packet sent to a single endstation on a network.
VLAN	Virtual LAN. A group of location- and topology-independent devices
	that communicate as if they are on the same physical LAN.
VLAN tagging	A system that allows traffic for multiple VLANs to be carried on a single
	link.
