NetEnforcer Failover
In case the Primary NetEnforcer fails, the unit will go in to bypass mode forwarding all
traffic directly to the network bypassing the failed NetEnforcer. The Secondary
NetEnforcer will go in to active mode forwarding all traffic via the secondary unit.
NetEnforcer functionality will be maintained.
In the unlikely situation where the Secondary unit fails, it will go in to bypass mode
bypassing the failed NetEnforcer. Network connectivity will maintain but all
NetEnforcer functionality will be lost.
Bypass unit is provided with each NetEnforcer units. In case of failover situation
(including power-loss), the links connected to the bypass will be wired (cross
connected) and traffic will not be disturbed. The bypass unit is a passive device and
does not require external power supply.
