This command displays the packet type filter settings on the specified ADSL port(s) 
or on all 
ADSL ports if no port is specified. 
The following example displays the packet type filter settings for ADSL port 9. 
A “V” in a column means that the port is set to allow that type of packets to 
pass through.

27.13.2    Packet Filter Set Command 
Syntax: 
switch pktfilter set <portlist> 
[pppoe|ip|arp|netbios|dhcp|eapol|igmp|none] 
where 
<portlist> 
=  You can specify a single ADSL port <1>, all ADSL ports <*> 
or a list of ADSL ports <1,3,5>. You can also include a range 
of ports 
<1,5,6~10>. 
[pppoe|ip|ar 
p|netbios|dh 
cp|eapol|igm 
p|none] 
=  [pppoe] Reject PPPoE packets. (Point-to-Point Protocol over 
Ethernet) relies on PPP and Ethernet. PPPoE 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]
 Reject IP packets. Internet Protocol. The underlying protocol 
for routing packets on the Internet and other TCP/IP-based 
networks. 
[arp] Reject ARP packets. 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] Reject NetBIOS packets. (Network Basic Input/Output 
System) are TCP or UDP broadcast packets that enable a 
computer to connect to and communicate with a LAN. 
[dhcp] Reject DHCP packets. 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.
