CONFIG Commands
Static ARP Settings
Your Netopia Gateway maintains a dynamic Address Resolution Protocol (ARP) table to map
IP addresses to Ethernet (MAC) addresses. Your Netopia Gateway populates this ARP table
dynamically, by retrieving IP address/MAC address pairs only when it needs them. Option-
ally, you can define static ARP entries to map IP addresses to their corresponding Ethernet
MAC addresses. Unlike dynamic ARP table entries, static ARP table entries do not time
out.
You can configure as many as 16 static ARP table entries for a Netopia Gateway. Use the
following commands to add static ARP entries to the Netopia Gateway static ARP table:
set ip static-arp ip-address
ip_address
Specifies the IP address for the static ARP entry. Enter an IP address in the
ip_address
argument in dotted decimal format. The
ip_address
argument cannot be 0.0.0.0.
set ip static-arp ip-address
ip_address
hardware-address
MAC_address
Specifies the Ethernet hardware address for the static ARP entry. Enter an Ethernet hard-
ware address in the
MAC_address
argument in
nn.nn.nn.nn.nn.nn
(hexadecimal) for-
mat.
IGMP Forwarding
set ip igmp-forwarding [ off | on ]
Turns IP IGMP forwarding off or on. The default is off.
IPsec Passthrough
