Lease Time
The
Lease Time
specifies the period of time the
DHCP
Server gives its clients an
IP Address
and other required information. When the lease expires, the client must request a new
lease. If the lease is set to a short span, you can update your network information and
propagate the information provided to the clients in a timely manner.
LLC
The
Logical Link Control
(LLC) layer controls frame synchronization, flow control, and error
checking. It is a higher level protocol over the
PHY
layer, working in conjunction with
the
MAC
layer.
MAC
The
Media Access Control
(MAC) layer handles moving data packets between
NIC
s across
a shared channel. It is a higher level protocol over the
PHY
layer. It provides an arbitration
mechanism in an attempt to prevent signals from colliding.
It uses a hardware address, known as the
MAC address
, that uniquely identifies each node
of a network.
IEEE 802 network devices share a common 48-bit MAC address format, displayed as a string
of twelve (12) hexadecimal digits separated by colons, for example FE:DC:BA:09:87:65.
MSCHAP V2
Microsoft Challenge Handshake Authentication Protocol Version 2
(MSCHAP V2) provides
authentication for
PPP
connections between a Windows-based computer and an
Access
Point
or other network access device.
MTU
The
Maximum Transmission Unit
is the largest physical packet size, measured in bytes, that
a network can transmit. Any messages larger than the MTU are fragmented into smaller
packets before being sent.
Multicast
A
Multicast
sends the same message to a select group of recipients. Sending an e-mail
message to a mailing list is an example of multicasting. In wireless networks, multicast
usually refers to an interaction in which the access point sends data traffic in the form of
IEEE 802.1x Frame
s to a specified set of client stations (
MAC
addresses) on the network.
Some wireless security modes distinguish between how unicast, multicast, and broadcast
frames are encrypted or whether they are encrypted.
