MIC
Message integrity code. The IEEE term for a message authentication code (MAC). See MAC.

MPDU
MAC protocol data unit. In IEEE 802.11 communications, the data unit (or frame) that two peer
media access control (MAC) service access points (SAPs) exchange through the services of the Physical layer
(PHY). An MPDU consists of MAC headers and a MAC service data unit (MSDU). See also MSDU.
MS-CHAP-V2
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 (MPDU).
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.
NAPA
Nortel Access Point Access protocol. A point-to-point datagram protocol, developed by Nortel, that
defines the way each AP communicates with a WLAN—Security Switch (WSS) in a Nortel WLAN 2300
system. By means of NAPA, APs announce their presence to the WSS, accept configuration from it, relay
traffic to and from it, announce the arrival and departure of users (clients), and provide statistics to the WSS on
command.
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.
