Using bypass switches for fail-over
Bypass switches are useful for fail-over purpose. They can be used for the occassional
maintenance required for FortiDDoS devices. Passive bypass switches are useful in
case of power failure. If both the FortiDDoS device and the failover switch share the
same power, external connectivity can still be maintained.
As shown in
, when the bypass switch is in disabled mode, the in-line traffic
continues to flow through the FortiDDoS device. This is the default mode.
Figure 15:
Bypass Switch in Disabled Mode
As shown in
, when the bypass switch is in bypass enabled mode, all in-line
traffic is routed through the bypass switch. In this mode, the switch allows the
FortiDDoS device to be removed and replaced without network downtime. Once
power is restored to the bypass switch, network traffic is seamlessly diverted to the
FortiDDoS device, allowing it to resume its critical functions.
