Information
During the time one port is down, operation is limited to a single port. It is not possible to distribute the bandwidth load across
2 ports.
-
Active-Standby connection
A method where 2 ports are used, and a single IP address is configured. Of the 2, only one port will be enabled (Active port),
and the other port will be disabled (Standby port). When the Active port is down, the IP address configuration can be passed
on to the Standby port which is automatically enabled, making it possible to continue operation with the same IP address
even after recovering from the down time.
-
Single connection
A method where 1 port is used, and a single IP address is configured. When the port goes down, it will not be possible to access
the shared folder.
Information
In order to continue business when a port is down, it is recommended to configure either Active-Active or Active-Standby connection
for redundancy.
Further, with the aim of increasing communication speed and becoming more fault-resilient, multiple physical ports can be
bundled and handled as one logical port. Further, a NAS interface can be allocated for that logical port (bonding port). The method
of determining communication ports of bonding port is to select an operating mode and hash policy.

Increase Communication Speed
Networks are bundled to increase communication speed.

Improved Fault-Resilience
When a communication fault occurs in any one of the bundled networks, the remaining networks can continue communication.
