message authentication code See MAC.
message-digest algorithm 5 See MD5.
message integrity code See MIC.
MIC Message integrity code. The IEEE term for a message authentication code (MAC). See MAC.
Microsoft Challenge Handshake Authentication
Protocol
See MS-CHAP-V2.
minimum data transmit rate The lowest rate at which a Access Point (AP) access point can
transmit data to its associated mobile clients. If the data rate to a client drops below the minimum, the AP
increases power, if RF Auto-Tuning is enabled.
Mobility Domain™ A collection of Wireless Security Switch (WSS) switches working together to
support a roaming user (client).
Wireless Security Switch™ (WSS™) A switch in a Nortel WLAN 2300 System. An WSS
provides forwarding, queuing, tunneling, and some security services for the information it receives from its
directly attached Access Point (AP) access ports. In addition, the WSS coordinates, provides power to, and
manages the configuration of each attached AP, by means of the Nortel access point Access (TAPA) protocol.
Mobility Profile™ A user (client) authorization attribute that specifies the Access Point (AP) access
ports or wired authentication ports the client can use in a Mobility Domain™ group.
MPDU MAC protocol data unit. In IEEE 802.11 communications, the data unit (or frame) that two peer
media access control (MAC) service access ports (SAPs) exchange through the services of the Physical layer
(PHY). An APDU consists of MAC headers and a MAC service data unit (MSDU). See also MSDU.
MS-CHAP-V2 Microsoft Challenge Handshake Authentication Protocol version 2. Microsoft’s extension
to CHAP. MS-CHAP-V2 is a mutual authentication protocol, defined in RFC 2759, that also permits a single
login in a Microsoft network environment. See also CHAP.
MSDU MAC service data unit. In IEEE 802.11 communications, the data payload encapsulated within a
MAC protocol data unit (APDU).
WSS Software See WLAN 2300 System Software™ (WSS Software™).
MTU Maximum transmission unit. The size of the largest packet that can be transmitted over a particular
medium. Packets exceeding the MTU value in size are fragmented or segmented, and then reassembled at the
receiving end. If fragmentation is not supported or possible, a packet that exceeds the MTU value is dropped.
NAT Network address translation. The capability, defined in RFC 3022, of using one set of reusable IP
addresses for internal traffic on a LAN, and a second set of globally unique IP addresses for external traffic.
network address translation See NAT.
network plan A design for network deployment and settings for network configuration, stored in the
Nortel WLAN 2300 System WLAN Management Software tool suite.
