set ip dsl vccn broadcast

broadcast_address

Speciﬁes the broadcast address for the TCP/IP network connected to the virtual circuit. IP

hosts use the broadcast address to send messages to every host on your network simulta-

neously.

The broadcast address for most networks is the network number followed by 255. For

example, the broadcast address for the 192.168.1.0 network would be 192.168.1.255.

set ip dsl vccn netmask

netmask

Speciﬁes the subnet mask for the TCP/IP network connected to the virtual circuit. The sub-

net mask speciﬁes which bits of the 32-bit binary IP address represents network informa-

tion. The default subnet mask for most networks is 255.255.255.0 (Class C subnet

mask).

set ip dsl

vccn

restrictions { admin-disabled | none }

Speciﬁes restrictions on the types of trafﬁc the Motorola Netopia® Gateway accepts over

the DSL virtual circuit. The

admin-disabled

argument means that access to the device

via telnet, web, and SNMP is disabled. RIP and ICMP trafﬁc is still accepted. The

none

argument means that all trafﬁc is accepted.

set ip dsl vccn addr-mapping { on | off }

Speciﬁes whether you want the Motorola Netopia® Gateway to use network address trans-

lation (NAT) when communicating with remote routers. Address mapping lets you conceal

details of your network from remote routers. It also permits all LAN devices to share a sin-

gle IP address. By default, address mapping is turned “On”.

set ip dsl vccn auto-sensing [ off | dhcp/pppoe | pppoe/pppoa ]

Enables or disables DHCP/PPPoE or PPPoE/PPPoA autosensing on the speciﬁed interface.

Setting this to

DHCP/PPPoE

enables automatic sensing of your WAN connection type:

PPPoE or DHCP. The gateway attempts to connect using PPPoE ﬁrst. If the Gateway fails to

connect after 60 seconds, it switches to DHCP. As soon as it can connect via DHCP, the

Gateway chooses and sets DHCP as its default. Otherwise, after attempting to connect via

DHCP for 60 seconds, the Gateway switches back to PPPoE. The Gateway will continue to

switch back and forth in this manner until it successfully connects. Similarly, selecting

Page 217 / 351

CONFIG Commands

PPPoE/PPPoA

causes the Gateway to attempt to connect by trying these protocols in par-

allel, and using the ﬁrst one that is successful.

set ip dsl vccn mcast-fwd [ on | off }

Enables or disables multi-cast forwarding on the speciﬁed interface. If set to

on

, this inter-

face acts as an IGMP proxy host, and IGMP packets are transmitted and received on this

interface on behalf of IGMP hosts on the LAN interface.

set ip dsl vccn igmp-null-source-addr { on | off }

Speciﬁes whether you want the Motorola Netopia® Gateway to identify the source IP

address of every IGMP packet transmitted from this interface as 0.0.0.0 when

mcast-fwd

is set to

on

. This complies with the requirements of TR-101, and removes the need for a

publicly advertised IP address on the WAN interface.

set ip dsl vccn unnumbered [ on | off }

Speciﬁes whether you want the Motorola Netopia® Gateway to have its WAN interface

unnumbered, i.e. set to 0.

unnumbered

option is only available if the address is set to 0

for the interface. Enables or disables unnumbered IP addressing (where an address of 0 is

allowed AND the DHCP client is disabled) on the speciﬁed interface. This setting applies to

native IP as well as PPP interfaces to support running an IPoE interface without an

address.

set ip dsl vccn rip-send { off | v1 | v2 | v1-compat | v2-MD5 }

Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol

(RIP) broadcasts to advertise its routing tables to other routers. RIP Version 2 (RIP-2) is an

extension of the original Routing Information Protocol (RIP-1) that expands the amount of

useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algo-

rithms, RIP-2 supports several additional features, including inclusion of subnet masks in

RIP packets and implementation of multicasting instead of broadcasting (which reduces

the load on hosts which do not support routing protocols. RIP-2 with MD5 authentication is

an extension of RIP-2 that increases security by requiring an authentication key when

routes are advertised.

Depending on your network needs, you can conﬁgure your Motorola Netopia® Gateway to

support RIP-1, RIP-2, or RIP-2MD5.

Page 218 / 351

218

If you specify

v2-MD5

, you must also specify a

rip-send-key

. Keys are ASCII strings with a

maximum of 31 characters, and must match the other router(s) keys for proper operation

of MD5 support.

set ip dsl vccn rip-receive

{ off | v1 | v2 | v1-compat | v2-MD5 }

Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol

(RIP) broadcasts to update its routing tables with information received from other routers.

If you specify

v2-MD5

, you must also specify a

rip-receive-key

. Keys are ASCII strings

with a maximum of 31 characters, and must match the other router(s) keys for proper oper-

ation of MD5 support.

Ethernet LAN Settings

set ip ethernet A option { on | off }

Enables or disables communications through the designated Ethernet port in the Gateway.

You must enable TCP/IP functions for an Ethernet port before you can conﬁgure its network

settings.

set ip ethernet A address

ip_address

Assigns an IP address to the Motorola Netopia® Gateway on the local area network. The IP

address you assign to the local Ethernet interface must be unique on your network. By

default, the Motorola Netopia® Gateway uses 192.168.0.1 as its LAN IP address.

set ip ethernet A broadcast

broadcast_address

Speciﬁes the broadcast address for the local Ethernet interface. IP hosts use the broad-

cast address to send messages to every host on your network simultaneously.

The broadcast address for most networks is the network number followed by 255. For

example, the broadcast address for the 192.168.1.0 network would be 192.168.1.255.

CONFIG Commands

set ip ethernet A netmask

netmask

Speciﬁes the subnet mask for the local Ethernet interface. The subnet mask speciﬁes

which bits of the 32-bit binary IP address represent network information. The default sub-

net mask for most networks is 255.255.255.0 (Class C subnet mask).

set ip ethernet A restrictions { none | admin-disabled }

Speciﬁes whether an administrator can open a telnet connection to a Motorola Netopia®

Gateway over an Ethernet interface (

A

= the LAN) to monitor and conﬁgure the unit.

The

admin-disabled

argument prevents access to the device via telnet, web, and SNMP.

By default, administrative restrictions are

none

on the LAN, but

admin-disabled

is set on

the WAN. This means that, by default, an administrator can open, for example, a telnet

connection from the LAN, but not the WAN.

set ip ethernet A rip-send

{ off | v1 | v2 | v1-compat | v2-MD5 }

Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol

(RIP) broadcasts to advertise its routing tables to other routers on your network. RIP Ver-

sion 2 (RIP-2) is an extension of the original Routing Information Protocol (RIP-1) that

expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share

the same basic algorithms, RIP-2 supports several additional features, including inclusion

of subnet masks in RIP packets and implementation of multicasting instead of broadcast-

ing (which reduces the load on hosts which do not support routing protocols. RIP-2 with

MD5 authentication is an extension of RIP-2 that increases security by requiring an authen-

tication key when routes are advertised.

If you specify

v2-MD5

, you must also specify a

rip-send-key

. Keys are ASCII strings with a

maximum of 31 characters, and must match the other router(s) keys for proper operation

of MD5 support.

Depending on your network needs, you can conﬁgure your Motorola Netopia® Gateway to

support RIP-1, RIP-2, or RIP-2MD5.

set ip ethernet A rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }

Speciﬁes whether the Motorola Netopia® Gateway should use Routing Information Protocol

(RIP) broadcasts to update its routing tables with information received from other routers

on your network.

If you specify

v2-MD5

, you must also specify a

rip-receive-key

. Keys are ASCII strings

with a maximum of 31 characters, and must match the other router(s) keys for proper oper-

ation of MD5 support.
