33.1.2 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 ''Step 1: Configure the First Device'' on page
607)
2. Configuring the second device for HA (see ''Step 2: Configure the Second Device'' on
page 609)
3. Activating HA on the devices (see ''Step 3: Initialize HA on the Devices'' on page 610)
Note:
•
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 ''License Key'' on page
641.
•
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 Settings'' on page 605.
•
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.

33.1.2.1 Step 1: Configure the First Device

The first stage is to configure the first device for HA, as described in the following
procedure:
Note:
disconnected from the network.

To configure the first device for HA:
1. Configure the network interfaces, including the default OAMP interface:
a. Connect your PC to the device using a local, direct physical cable connection and
then access the Web interface using the default OAMP network address. For
more information on initial access, see Assigning the OAMP IP Address on page
37.
b. Open the IP Interfaces table (see ''Configuring IP Network Interfaces'' on page
129).
c. Change the default OAMP network settings to suit your networking scheme.
d. Configure the Control and Media network interfaces, as required.
Version 7.2
During this stage, make sure that the second device is powered off or
