The following table describes the labels in this screen.
Table 47 Packet Filter
LABEL DESCRIPTION
Port Use this drop-down list box to select a DSL port for which you wish to
configure packet type filtering. This box is read-only after you click on
one of the port numbers in the table below.
PPPoE Only Select this to allow only PPPoE traffic. This will gray out the check
boxes for other packet types and the system will drop any non-PPPoE
packets.
Select the check boxes of the types of packets to accept on the DSL
port. When you clear one of these check boxes, the field label
changes to Filter Out and the system drops the corresponding type
of 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
Apply
Click Add or Apply to save the filter settings. The settings then
display in the summary table at the bottom of the screen.
Clicking Add or Apply saves your changes to the SAM1316-22’s
volatile memory. The SAM1316-22 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 fields afresh.
