Figure 132: Link Backup Configuration

Set the Name field to supply an identification of the pair. This field initially defaults to the “main_link_name->backup_link_name”.

The Enable this configuration field enables this backup.

The Transfer default gateway field causes the gateway to be transferred to the backup link upon failure of the main link path. If the backup interface is point to point, such as PPP, the Backup gateway IP address can be automatically determined. Non-point to point interfaces such as Ethernet must be configured with one. The Bring up backup link on demand option allows protocols such as DHCP to be used to fetch an address when required.

The Startup Delay field configures the length of time to wait for the main link to come up at the start of day.

Note: If Startup Delay is too low, backup will be falsely triggered at start up.

The Ping Interval field configures how often pings are sent.

The Ping timeout field configures the duration before immediately retrying a ping.

The Ping retry count field configures the number of ping retries before construing a path failure.

Note: The maximum time to discover a path failure is the length of the Ping Interval and the product of the Number of missed pings before fail over and the Ping timeout.

The Main path down timeout field specifies the number of seconds the main trunk must be down before starting the backup trunk.

The Main path up timeout field specifies the number of seconds the main trunk must have returned to service before stopping the backup trunk.

You may delete a link backup configuration through the Delete button.
