Point-to-Point Protocol over Ethernet relies on PPP and Ethernet. It is a specification
for connecting the users on an Ethernet to the Internet through a common broadband
medium, such as a single DSL line, wireless device or cable modem.
Internet Protocol. The underlying protocol for routing packets on the Internet and
other TCP/IP-based networks.
Address Resolution Protocol is a protocol for mapping an Internet Protocol address
(IP address) to a physical computer address that is recognized in the local network.
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable
a computer to find other computers.
Dynamic Host Configuration Protocol automatically assigns IP addresses to clients
when they log on. DHCP centralizes IP address management on central computers
that run the DHCP server program. DHC P leases addresses, for a period of time,
which means that past addresses are “recycled” and made available f or future
reassignment to other systems.
EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used with
IEEE 802.1x to allow additional authentication methods (besides RADIUS) to be
deployed with no changes to the access point or the wireless clients.
Internet Group Multicast Protocol is used when sending packets to a specific group of
hosts.

Add Click Add to save your settings. The VLAN then displays in the summary table at
the top of the screen.
Clicking Add saves your changes to the MSAP2000 AAMS’s volatile memory. The
MSAP2000 AAMS loses these changes if it is turned off or loses power, so use
the Config Save link on the navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring the screen again.
This table shows the ADSL port packet filter settings.
Port These are the numbers of the ADSL ports. Click this number to edit the port’s
filter settings.
PPPoE, IP, ARP, These are the packet filter settings f or each port.
NetBios, DHCP, “V” displays for the packet types that the MSAP2000 AAMS is to
accept on the port. “-” displays EAPO, IGMP, for packet types that the MSAP2000
AAMS is to reject on the port. “#” displays for the packet PPPoE Only fi lter settings
that the MSAP2000 AAMS ignores.
