7.13 Service Mode

The following devices support the service mode:
RS20/RS30/RS40 and MS20/MS30.
The service mode enables you to divide the device into 2 transmission areas.
You can thus, for example, perform test or service configurations in the field
area of a network while the ongoing operation continues in the backbone
area.
The device specifies the two transmission areas via the HIPER-Ring ports:
transmission area 1 only includes the HIPER-Ring ports of the device, while
all other ports belong to transmission area 2. When the service mode is
activated, the device creates a new VLAN in which all the ports of
transmission area 2 are members. You use the redundant supply voltage
(see below) to activate the service mode. You can view the configuration of
the newly created VLAN in the dialogs under Switching/VLAN, but the device
does not allow these entries to be changed, in order to keep the service
configuration.
By generating the VLAN, the device
 resets the port VLAN IDs for all the ports of this VLAN to the new VLAN ID
 deactivates GVRP at all ports of this VLAN. The device prevents GVRP
from dynamically changing the service mode port settings as a result.
 activates "Ingress Filtering" at all ports of this VLAN. As a consequence,
the device only transmits packets when the input and output ports belong
to this VLAN.
