Spanning Tree Protocol (STP)

A protocol that finds the most efficient path between segments of a multi-looped, bridged network. STP

allows redundant switches and bridges to be used for network resilience, without the broadcast storms

associated with looping. If a switch or bridge falls, a new path to a redundant switch or bridge is opened.

Subnet Mask

Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local

to it, and which must be reached through a gateway or router.

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.

TFTP

Trivial File Transfer Protocol. Allow you to transfer files (such as software upgrades) from a remote device

using the local management capabilities of the switch.

TLS

Short for Transport Layer Security, TLS is a protocol that guarantees privacy and data integrity between

client/server applications communicating over the Internet.

The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by

using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the

TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of

an encryption algorithm and cryptographic keys before data is transmitted or received. Based on Netscape’s

SSL 3.0, TLS supercedes and is an extension of SSL. TLS and SSL are not interoperable.

Telnet

A TCP/IP application protocol that provides a virtual terminal service, allowing a user to log into another

computer system and access a device as if the user were connected directly to the device.

Traffic prioritization

Giving time-critical data traffic a higher quality of service over other, non-critical data traffic.

UTP

Unshielded twisted pair is the cable used by 10BASE-T and 100BASE-Tx Ethernet networks.

Unicast

A packet sent to a single end station on a network.

VLAN

Virtual LAN. A logical association that allows users to communicate as if they were physically connected to

a single LAN, independent of the actual physical configuration of the network.
