The operative condition of a hardware unit. The Active identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit.
The actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. Qualification of failure is achieved by various configurable physical and logical monitoring facilities described in Configuring High Availability.
High Availability: non-state, hardware failover capability.
Interface Disambiguation through VLAN.
Power over Ethernet is a technology that lets network cables carry electrical power.
Point-to-point protocol that provides a standard method for transporting multi-protocol diagrams over point-to-point links.
A method for transmitting PPP over ethernet.
HA PPPoE support function without State.
Applies to a post-failover condition in which the Primary unit has failed, and the Secondary unit has assumed the Active role. Enabling Preempt causes the Primary unit to seize the Active role from the Secondary after the Primary has been restored to a verified operational state.
The principal hardware unit itself. The Primary identifier is a manual designation and is not subject to conditional changes. Under normal operating conditions, the Primary hardware unit operates in an Active role.
The subordinate hardware unit itself. The Secondary identifier is a relational designation and is assumed by a unit when paired with a Primary unit. Under normal operating conditions, the Secondary unit operates in a Standby mode. Upon failure of the Primary unit, the Secondary unit assumes the Active role.
State Hardware Failover, a SonicOS feature that allows existing network flows to remain active when the primary Security Appliance fails and the backup Security Appliance takes over.
The passive condition of a hardware unit. The Standby identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. The Standby unit assumes the Active role upon a determinable failure of the Active unit.
