e. Add the HA Maintenance interface (i.e., the MAINTENANCE Application Type).
Note: Make sure that the Maintenance interface uses an Ethernet Device and
Ethernet Group that is not used by any other IP network interface. The Ethernet
Group is associated with the Ethernet Device, which is assigned to the interface.
The IP Interfaces table below shows an example where the Maintenance interface is
configured with Ethernet Device "vlan 2" (which is associated with Ethernet Group
"GROUP_2"), while the other interface is assigned "vlan 1" (associated with Ethernet
Group "GROUP_1"):
2. If the connection is through a switch, the packets of both interfaces should generally
be untagged. To do this, open the Ethernet Devices table (see ''Configuring
Underlying Ethernet Devices'' on page 127 ), and then configure the 'Tagging'
parameter to Untagged for the Ethernet Device assigned to the Maintenance
interface. The figure below shows an example (highlighted) where VLAN 2 is
configured as the Native (untagged) VLAN ID of the Ethernet Group "GROUP_2":
Figure 33-5: Configuring Untagged VLAN for Maintenance and Other Interfaces
3. Set the Ethernet port Tx / Rx mode of the Ethernet Group used by the Maintenance
interface (see ''Configuring Ethernet Port Groups'' on page 125). The port mode
depends on the type of Maintenance connection between the devices, as described in
''Network Topology Types and Rx/Tx Ethernet Port Group Settings'' on page 605.
4. Configure HA parameters:
a. Open the HA Settings page (Setup menu > IP Network tab > Core Entities
folder > HA Settings):
b. In the 'HA Remote Address' field, enter the Maintenance IP address of the
second device.
