About CONFIG Commands

When you are in step mode, the command line interface prompts you to enter required and

optional settings. If a setting has a default value or a current setting, the command line

interface displays the default value for the command in parentheses. If a command has a

limited number of acceptable values, those values are presented in brackets, with each

value separated by a vertical line. For example, the following CLI step command indicates

that the default value is

off

and that valid entries are limited to

on

and

off

.

option (off) [on | off]: on

You can accept the default value for a ﬁeld by pressing the Return key. To use a different

value, enter it and press Return.

You can enter the CONFIG step mode by entering

set

from the top node of the CONFIG hier-

archy. You can enter step mode for a particular service by entering

set

service_name

.

In stepping set mode (press Control-X <Return/Enter> to exit. For example:

Validating Your Conﬁguration

You can use the

validate

CONFIG command to make sure that your conﬁguration set-

tings have been entered correctly. If you use the

validate

command, the Netopia Gate-

way veriﬁes that all required settings for all services are present and that settings are

consistent.

Netopia-3000/9437188 (top)>>

validate

Error: Subnet mask is incorrect

Global Validation did not pass

inspection!

You can use the

validate

command to verify your conﬁguration settings at any time.

Your Netopia Gateway automatically validates your conﬁguration any time you save a modi-

ﬁed conﬁguration.

CONFIG Commands

This section describes the keywords and arguments for the various CONFIG commands.

DSL Commands

ATM Settings.

You can use the CLI to set up each ATM virtual circuit.

set atm option {on | off }

Enables the WAN interface of the Netopia Gateway to be conﬁgured using the Asynchro-

nous Transfer Mode (ATM) protocol.

set atm [vcc

n

] option {on | off }

Selects the virtual circuit for which further parameters are set. Up to eight VCCs are sup-

ported; the maximum number is dependent on your Netopia Operating System tier and the

capabilities that your Service Provider offers.

set atm [vcc

n

] qos service-class { cbr | ubr | vbr }

Sets the Quality of Service class for the speciﬁed virtual circuit – Constant (

cbr

), Unspeci-

ﬁed (

ubr

), or Variable (

vbr

) Bit Rate.

•

ubr

: No conﬁguration is needed for UBR VCs. Leave the default value 0 (maximum line

rate).

•

cbr

: One parameter is required for CBR VCs. Enter the

Peak Cell Rate

that applies to

the VC. This value should be between 1 and the line rate. You set this value according

to speciﬁcations deﬁned by your service provider.

•

vbr

: Three parameters are required for VBR VCs. Enter the

Peak Cell Rate

, the

Sus-

tained Cell Rate

, and the

Maximum Burst Size

that apply to the VC. You set these

values according to speciﬁcations deﬁned by your service provider.

set atm [vcc

n

] qos peak-cell-rate { 1 ...

n

}

If QoS class is set to

cbr

or

vbr

then specify the

peak-cell-rate

that should apply to the

speciﬁed virtual circuit. This value should be between 1 and the line rate.

The Peak Cell Rate (PCR) should be set to the maximum rate a PVC can oversubscribe its

Sustained Cell Rate (SCR). The Peak Cell Rate (see below) must be less than, or equal to

Page 243 / 351

243

CONFIG Commands

the raw WAN (DSL) bit rate. The Maximum Burst Size (MBS) is the number of cells that can

be sent at the PCR rate, after which the PVC must fall back to the SCR rate.

set atm [vcc

n

] qos sustained-cell-rate { 1 ...

n

}

If QoS class is set to

vbr

, then specify the

sustained-cell-rate

that should apply to the

speciﬁed virtual circuit. This value should be less than, or equal to the Peak Cell Rate,

which should be less than, or equal to the line rate.

set atm [vcc

n

] qos max-burst-size { 1 ...

n

}

If QoS class is set to

vbr

then specify the

max-burst-size

that should apply to the speci-

ﬁed virtual circuit. This value is the maximum number of cells that can be transmitted at

the Peak Cell Rate after which the ATM VC transmission rate must drop to the Sustained

Cell Rate.

set atm [vcc

n

] vpi { 0 ... 255 }

Select the virtual path identiﬁer (vpi) for VCC n.

Your Service Provider will indicate the required vpi number.

set atm [vcc

n

] vci { 0 ... 65535 }

Select the virtual channel identiﬁer (vci) for VCC n. Your Service Provider will indicate the

required vci number.

set atm [vccn] encap { ppp-vcmux | ppp-llc | ether-llc |

ip-llc | ppoe-vcmux | pppoe-llc }

Select the encapsulation mode for VCC n. The options are:

ppp-vcmux

PPP over ATM, VC-muxed

ppp-llc

PPP over ATM, LLC-SNAP

ether-llc

RFC-1483, bridged Ethernet, LLC-SNAP

ip-llc

RFC-1483, routed IP, LLC-SNAP

pppoe-vcmux

PPP over Ethernet, VC-muxed

pppoe-llc

PPP over Ethernet, LLC-SNAP

Page 244 / 351

244

Your Service Provider will indicate the required encapsulation mode.

set atm [vccn]

pppoe-sessions { 1 ... 8 }

Select the number of PPPoE sessions to be conﬁgured for

VCC 1, up to a total of eight. The total number of

pppoe-sessions

and PPPoE VCCs conﬁg-

ured must be less than or equal to eight.

Bridging Settings

Bridging lets the Netopia Gateway use MAC (Ethernet hardware) addresses to forward non-

TCP/IP trafﬁc from one network to another. When bridging is enabled, the Netopia Gateway

maintains a table of up to 512 MAC addresses. Entries that are not used within 30 sec-

onds are dropped. If the bridging table ﬁlls up, the oldest table entries are dropped to

make room for new entries.

Virtual circuits that use IP framing cannot be bridged.

☛

NOTE:

For bridging in the 3341 (or any model with a USB port), you cannot set the

bridge option

off

, or

bridge ethernet option off

; these are on by default

because of the USB port.

Common Commands

set bridge sys-bridge

{on | off }

Enables or disables bridging services in the Netopia Gateway. You must enable bridging

services within the Netopia Gateway before you can enable bridging for a speciﬁc inter-

face.

set bridge concurrent-bridging-routing

{on | off }

Enables or disables Concurrent Bridging/Routing.

Page 245 / 351

245

CONFIG Commands

set bridge ethernet option { on | off }

Enables or disables bridging services for the speciﬁed virtual circuit using Ethernet fram-

ing.

set bridge dsl vcc

n

option { on | off }

Enables or disables bridging services for the speciﬁed interface. Speciﬁed interface must

be part of a VLAN if bridge is turned

on

. Only RFC-1483 Bridged encapsulation is sup-

ported currently.

•

show log

command will show that WAN Bridge is enabled when at least one WAN inter-

face is bridged.

•

show ip interfaces

and

show bridge interfaces

commands will show the interfaces

that are not in bridged mode and that are in bridged modes, respectively.

set bridge table-timeout [ 30 ... 6000 ]

Sets the timeout value for bridging table timeout. Default = 30 secs; range = 30 secs –

6000 secs (.5–100 mins).

DHCP Settings

As a Dynamic Host Control Protocol (DHCP) server, your Netopia Gateway can assign IP

addresses and provide conﬁguration information to other devices on your network dynami-

cally. A device that acquires its IP address and other TCP/IP conﬁguration settings from the

Netopia Gateway can use the information for a ﬁxed period of time (called the DHCP lease).

Common Commands

set dhcp option { off | server | relay-agent }

Enables or disables DHCP services in the Netopia Gateway. You must enable DHCP ser-

vices before you can enter other DHCP settings for the Netopia Gateway.

If you turn off DHCP services and save the new conﬁguration, the Netopia Gateway clears

its DHCP settings.
