● Standby Function
Note
Device with the higher MAC address becomes master
When linking HRP rings redundantly, two devices are always configured as a
master/slave pair. This also applies to interrupted HRP rings = linear buses. When
operating normally, the device with the higher MAC address adopts the role of master.
This type of assignment is important in particular when a device is replaced. Depending
on the MAC addresses, the previous device with the slave function can take over the role
of the standby master.
The "Standby Function" display box shows the status of the standby function:
– Master:
– Slave:
– Disabled:
– Waiting for Connection
– Connection Lost:

Configuration using Web Based Management and Command Line Interface
The device has a connection to the partner device and is operating as master. In
normal operation, the standby ports of this device are active.
The device has a connection to the partner device and is operating as slave. In normal
operation, the standby ports of this device are inactive.
Standby link is disabled. The device is operating neither as master nor slave. The
standby ports are working as normal ports without standby function.
No connection has yet been established to the partner device. The standby ports are
inactive. In this case, either the configuration on the partner device is inconsistent (for
example incorrect connection name, standby link disabled) or there is a physical fault
(for example device failure, link down).
Existing connection to the partner device has been lost. In this case there is either a
physical fault (for example, device failure, link down) or the configuration on the
partner device was modified (for example different connection name, standby link
disabled).
