4. Configuration Options

Restricting Automatic Backup and Configuring Backup Timers

You can specify when auto backup is allowed to occur. If backup is restricted and a backup is active when the allowed time for backups is over, then the backup is terminated and the data is returned to the primary data path regardless of the primary path’s condition.

You can restrict auto backup to occur only:

On certain days of the week

At certain times of the day

he following additional features can be configured:

Delays can be configured to control how long the unit will wait before initiating backup when a DLCI is declared down, and how long it will wait to restore

Tservice once the DLCI is declared operational again.

A threshold can be set to determine how many times a primary destination DLCI can transition between Active and Inactive before the unit initiates backup.

Procedure

To set the criteria and backup timers for automatic backup:

1. Enable Auto Backup.

Main Menu → Configuration → Auto-Backup Criteria

When a failure occurs, the unit automatically enables the Alternate Link and traffic is rerouted over the backup (alternate) interface.

2.Specify the amount of delay after a DLCI is declared down before backup is initiated (DLCI Down Backup Activation Delay).

3.Set the threshold for transitions of the DLCI’s status before backup is initiated (DLCI Down Backup Activation Transmission Threshold).

4.Specify the amount of delay after a DLCI is declared operation before backup is ended (Backup Restoration Delay).

5.Specify When Auto Backup Allowed – Always or Restrict. If Restrict is selected, specify the days and hours of the week during which automatic backup can take place.

6.Save the configuration.

See Table 4-26, Auto Backup Criteria Options, for configuration information.
