due to SureLink connectivity failure, and increased when SureLink succeedsagain.

Along with the priority settingsfor devices in this VRRPpool, the amount entered here should

be large enough to automatically demote a master device when SureLink connectivity fails. For

example, if the VRRPmaster device has a priority of 100 and the backup device hasa priority

of 80, then the Priority modifier should be set to an amount greater than 20 so that if

SureLink fails on the master, it will lower itspriority to below 80, and the backup device will

assume the master role.
