ZyWALL (ZLD) CLI Reference Guide

[no] network-selection {auto|home}

Home network is the network to which you are originally subscribed. 

Home

 has the 3G device connect only to the home network. If the 

home network is down, the ZyWALL's 3G Internet connection is also 
unavailable.

Auto 

is the default setting and allows the 3G device to connect to a 

network to which you are not subscribed when necessary, for example 
when the home network is down or another 3G base station's signal is 
stronger. This is recommended if you need continuous Internet 
connectivity. If you select this, you may be charged using the rate of a 
different network.  

[no] budget active

Sets a monthly limit for the user account of the installed 3G card. You 
can set a limit on the total traffic and/or call time. The ZyWALL takes 
the actions you specified when a limit is exceeded during the month. 
Use the no command to disable budget control.

[no] budget time active <1..672>

Sets the amount of time (in hours) that the 3G connection can be 
used within one month. If you change the value, the ZyWALL resets 
the statistics. Use the no command to disable time budget control.

[no] budget data active {download-

upload|download|upload} <1..100000>

Sets how much downstream and/or upstream data (in Mega bytes) 
can be transmitted via the 3G connection within one month.

download

: set a limit on the downstream traffic (from the ISP to the 

ZyWALL).

upload

: set a limit on the upstream traffic (from the ZyWALL to the 

ISP).

download-upload

: set a limit on the total traffic in both directions.

If you change the value, the ZyWALL resets the statistics.

Use the no command to disable data budget control.

budget reset-day <0..31>

Sets the date on which the ZyWALL resets the budget every month. If 
the date you selected is not available in a month, such as 30th or 
31st, the ZyWALL resets the budget on the last day of the month.

budget reset-counters

Resets the time and data budgets immediately. The count starts over 
with the 3G connection’s full configured monthly time and data 
budgets. This does not affect the normal monthly budget restart.

budget {log|log-alert}[recursive 

<1..65535>]

Sets the ZyWALL to create a log (log) or an alert log (log-alert) when 
the time or data limit is exceeded. You can also specify how often 
(from 1 to 65535 minutes) to generate a log or an alert.

no budget log [recursive]

Sets the ZyWALL to not create a log when the time or data limit is 
exceeded. Specify recursive to have the ZyWALL only create a log 
one time when the time or data limit is exceeded.

budget new-connection {allow|disallow}

Sets to permit (allow) or drop/block (disallow) new 3G connections 
when the time or data limit is exceeded.

budget current-connection {keep|drop}

Sets to maintain the existing 3G connection (keep) or disconnect it 
(drop) when the time or data limit is exceeded. You cannot set budget 
new-connection to allow and budget current-connection to drop at 
the same time. 

If you set budget new-connection to disallow and budget current-
connection to keep, the ZyWALL allows you to transmit data using the 
current connection, but you cannot build a new connection if the 
existing connection is disconnected.
