Introduction

To set up a Bandwidth on Demand installation, you must choose the throughput level that will be required for activating the stand-by link. The throughput level is measured in percentage of use of the primary link. This percentage level is defined by the Up Threshold parameter in the Secondary Activation Menu and may be set to any value from 50% to 100%.

A timer must be defined to determine the length of time to wait before bringing up the stand-by link. The Up Stability Timer parameter in the Secondary Activation Menu is used to define how long in minutes (from 1 to 60) the main link must exceed the threshold before the stand-by link is started.

Once the activation-throughput threshold has been determined and set, you must decide what the throughput threshold will have to be to drop the second link and operate on the main link only.

The Down Threshold level is set in the Secondary Activation Menu and defaults to 10% lower than the Up Threshold level. Remember that the down threshold looks at the total throughput (both links together) to determine if the second link will be brought down. The Down Threshold is defined as the percentage of the main links bandwidth the current total throughput represents. When the total throughput drops below the Down Threshold, the second link will be dropped.

A timer must also be defined to determine the length of time to wait before dropping the stand-by link. The Down Stability Timer parameter in the Secondary Activation Menu is used to define how long in minutes (from 1 to 60) the combined links’ throughput must remain below the down threshold level before the stand-by link is stopped.

Time of Day Connect Application

In addition to the Bandwidth on Demand feature, the P840 router has the ability to establish link connections based on a specific time-of-day schedule. Either one or two links may be controlled using the Time of Day feature. The Time of Day feature may also be used in conjunction with the Bandwidth on Demand feature. It may be used in both Multipoint and Multilink configurations.

Operating Software Upgrades

The P840 router includes flash memory, that allows new system code to be downloaded using the Trivial File Transfer Protocol (TFTP). This allows software updates to be performed quickly and painlessly from a host server (with TFTP capabilities) on the network.

The P840 router also allows the downloading of software updates by using a direct management port connection and the ZMODEM transfer protocol.
