Define a Failover Configuration

The amount of bandwidth that the unit manages can change if a router fails over from a primary to a secondary link. PacketWise can be configured to detect this failover condition and enforce the new, lower link speed. A site router must be defined in the unit's basic configuration before defining a failover configuration.

PacketWise polls the site router, using SNMP, every two seconds to determine the status of the links. If the site router uses another link as a backup for a primary link, PacketWise uses the failover settings to adjust its link speed during the primary link outage. Failover status is reported on the Info page.

PacketWise will detect the end of an outage and revert to the original bandwidth allocation as soon as the router reports the primary link is up again.

Note: To define failover settings from PolicyCenter, you must first select a group and/or unit configuration from the Group: and Unit: drop-down lists at the top of the page.
