Trap A trap is used within SNMP to report an unexpected or unallowable

condition.

Trivial File Transfer Protocol (TFTP) Trivial File Transfer Protocol (TFTP) is a lightweight protocol for transferring

files that is like a simple form of File Transfer Protocol (FTP). A TFTP client is

implemented on the unit. By using the upload and download commands,

the unit can copy a file to or from a TFTP server. TFTP server software is

provided on the product CD-ROM.

Unicast Unicast transmission is the sending of messages to a single network

destination identified by a unique address.

Untagged Frames Untagged frame is a frame which not added with a tag or has no VLAN Id

associated to it.

Upload Uploading a file means copying a file from a network device to a remote

server. In case of the unit, uploading means transferring a file from the

unit to a TFTP server. See also download.

Upstream / Uplink Upstream means a data stream from the end users to the central part of

the network. See also Downstream / Downlink.

VLAN The Virtual Local Area Network (VLAN) feature helps in logical grouping of

network host on different physical LAN segments, which can

communicate with each other as if they are all on the same physical LAN

segment.

WEP The Wired Equivalent Privacy (WEP) algorithm is the standard encryption

method used to protect wireless communication from eavesdropping.

Wireless Client / Station (STA) A computer or program, connected to an access point network, that can

access the wireless network, download files for manipulation, run

applications, or request application-based services from a file server is

called a wireless client or a wireless station (STA).

WLAN A flexible data communication system implemented as an extension to or

as an alternative for a wired LAN within a building or campus. By using

electromagnetic waves, WLANs transmit and receive data over the air,

minimizing the need for wired connections.

WPA Wi-Fi Protected Access is a Wi-Fi security standard that provides a high

level of wireless network security. It uses data encryption through the

Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys and

ensures that the keys haven't been tampered with. User authentication is

performed through the Extensible Authentication Protocol (EAP), to

ensure that only authorized network users can access the network.
