DWS-1008 User's Manual
subnet mobility
The ability of a wireless user (client) to roam across DWL-8220AP access points and
DWS-1008 switches in a virtual LAN (VLAN) while maintaining a single IP address and
associated data sessions.
supplicant
A client that is attempting to access a network.
syslog server
A remote repository for log messages. D-Link Mobility System Software (MSS) supports up
to four syslog servers on virtual LANs (VLANs) whose locations are configurable. MSS log
protocol complies with RFC 3164.
TAPA™
Trapeze Access Point Access™ protocol. A point-to-point datagram protocol, developed
by D-Link, that defines the way each DWL-8220AP access point communicates with a
DWS-1008 switch in a D-Link Mobility System. By means of TAPA, DWL-8220AP access
points announce their presence to the switch, accept configuration from it, relay traffic to and
from it, announce the arrival and departure of users (clients), and provide statistics to the
switch on command.
Temporal Key Integrity Protocol
See TKIP.
TKIP
Temporal Key Integrity Protocol. A wireless encryption protocol that fixes the known problems
in the Wired-Equivalent Privacy (WEP) protocol for existing IEEE 802.11 products. Like
WEP, TKIP uses RC4 ciphering, but adds functions such as a 128-bit encryption key, a
48-bit initialization vector, a new message integrity code (MIC), and initialization vector (IV)
sequencing rules to provide better protection. See also 802.11i; CCMP.
TLS
Transport Layer Security protocol. An authentication and encryption protocol that is the
successor to the Secure Sockets Layer (SSL) protocol for private transmission over the
Internet. Defined in RFC 2246, TLS provides mutual authentication with nonrepudiation,
encryption, algorithm negotiation, secure key derivation, and message integrity checking.
TLS has been adapted for use in wireless LANs (WLANs) and is used widely in IEEE 802.1X
authentication. See also EAPTLS; PEAP; TTLS.
TLV
Type, length, and value. A methodology for coding parameters within a frame. Type indicates a
parameter's type, length indicates the length of its value, and value indicates the parameter's
value.
Transport Layer Security protocol
