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.
