MSAP2000 AAMS User’s Guide

Table 31 Packet Filter (continued)

LABEL	DESCRIPTION
PPPoE Only	Select this check box to allow only PPPoE traffic. This will gray out the check boxes
	for other packet types and the MSAP2000 AAMS will drop any non-PPPoE packets.
PPPoE Pass	Point-to-Point Protocol over Ethernet relies on PPP and Ethernet. It is a specification
through	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.
IP Pass through	Internet Protocol. The underlying protocol for routing packets on the Internet and
	other TCP/IP-based networks.
ARP Pass	Address Resolution Protocol is a protocol for mapping an Internet Protocol address
through	(IP address) to a physical computer address that is recognized in the local network.
NetBios Pass	NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable
through	a computer to find other computers.
DHCP Pass	Dynamic Host Configuration Protocol automatically assigns IP addresses to clients
through	when they log on. DHCP centralizes IP address management on central computers
	that run the DHCP server program. DHCP leases addresses, for a period of time,
	which means that past addresses are “recycled” and made available for future
	reassignment to other systems.
EAPOL Pass	EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used with
through	IEEE 802.1x to allow additional authentication methods (besides RADIUS) to be
	deployed with no changes to the access point or the wireless clients.
IGMP Pass	Internet Group Multicast Protocol is used when sending packets to a specific group of
through	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 for 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 filter settings
	that the MSAP2000 AAMS ignores.
