CONFIG Commands

set ip ethernet A netmask

netmask

Specifies the subnet mask for the local Ethernet inter face. The subnet mask specifies
which bits of the 32-bit binar y 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 inter face (

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 adver tise 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 suppor ts 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 suppor t 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 adver tised.

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 suppor t.

Depending on your network needs, you can configure your Motorola Netopia® Gateway to
suppor t RIP-1, RIP-2, or RIP-2MD5.
