PPPoE Only Select this check box to allow only PPPoE traffic. This will gray out the check boxes
for other packet types and the AAM will drop any non-PPPoE packets.
PPPoE Pass
through
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.
IP Pass
through
Internet Protocol. The underlying protocol for routing packets on the Internet and
other TCP/IP-based networks.
ARP Pass
through
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 Pass
through
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable
a computer to find other computers.
DHCP Pass
through
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. 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
through
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.
IGMP Pass
through
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 AAM’s volatile memory. The AAM 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, NetBios,
DHCP, EAPO,
IGMP, PPPoE
Only
These are the packet filter settings for each port.
“V” displays for the packet types that the AAM is to accept on the port. “-” displays for
packet types that the AAM is to reject on the port. “#” displays for the packet filter
settings that the AAM ignores.
