CHAPTER 32 HA Configuration
■ For Geographical HA (both units are located far from each other), 2Rx/1Tx port mode
connected to a port aggregation switch is the recommended option:

Configuring the HA Devices

To initially configure the two devices comprising the HA system, do the following procedures listed
in chronological order:
1. Configuring the first device for HA (see
2. Configuring the second device for HA (see
3. Activating HA on the devices (see

When two LAN switches are used, the LAN switches must be in the same subnet
(i.e., broadcast domain).
To configure Rx/Tx modes of the Ethernet ports, see
Groups
The HA feature is available only if both devices are installed with a License Key
that includes this feature. For installing a License Key, see
The physical connections of the first and second devices to the network (i.e.,
Maintenance interface and OAMP, Control and Media interfaces) must be
identical. This also means that the two devices must also use the same Ethernet
Groups and the port numbers belonging to these Ethernet Groups. For example, if
the first device uses Ethernet Group 1 (with ports 1 and 2), the second device must
also use Ethernet Group 1 (with ports 1 and 2).
Before configuring HA, determine the required network topology, as described in
Network Topology Types and Rx/Tx Ethernet Port Group
The Maintenance network should be able to perform a fast switchover in case of
link failure and thus, Spanning Tree Protocol (STP) should not be used in this
network; the Ethernet connectivity of the Maintenance interface between the two
devices should be constantly reliable without any disturbances.
Step 1: Configure the First
