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 binary IP address represent network information. The default subnet 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) broad-

casts to advertise its routing tables to other routers on your network. 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 algorithms, RIP-2 supports several additional fea-

tures, 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.

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) broad-

casts 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 operation of MD5 support.

Additional subnets

See “DHCP Settings” on page 248 for subnet range conﬁguration commands.

set ip ethernet A subnet [ 2 ... 8 ] option [ on | off ]

Enables or disables additional LAN subnets. Up to seven additional subnets may be conﬁgured.
