Set Up High Availability Configure an Active/Passive Pair

Step 4 Set up the control link connection.

This example shows an in-band port that

is set to interface type HA.

For devices that use the management port

as the control link, the IP address

information is automatically

pre-populated.

1. In

Device > High Availability > General, edit the Control Link

(HA1)

section.

2. Select the interface that you have cabled for use as the HA1 link

in the

Port drop down menu. Set the IP address and netmask.

Enter a Gateway IP address only if the HA1 interfaces are on

separate subnets. Do not add a gateway if the devices are directly

connected.

Step 5 (Optional) Enable encryption for the

control link connection.

This is typically used to secure the link if

the two devices are not directly

connected, that is if the ports are

connected to a switch or a router.

device.

a. Select

Device > Certificate Management > Certificates >

Device Certificates.

b. Select Export HA key. Save the HA key to a network location

that the peer device can access.

c. On the peer device, navigate to

Device > Certificate

Management > Certificates > Device Certificates,

and

select

Import HA key to browse to the location that you saved

the key and import it in to the peer device.

2. Select

Device > High Availability > General, edit the Control

Link (HA1)

section.

3. Select
