Secure Communication between HA devices

It's recommended to secure communication between the active and redundant devices in the High-Availability (HA) system. HA communication occurs through the device's Maintenance IP Interface, which is used for HA synchronization, including file transfer between devices.

➢

To secure file transfer between HA devices:

1.

Open the HA Settings page (Setup menu > IP Networktab > Core Entities folder > HA Settings).

2.

Select the 'HA Secured Connectivity Mode' check box.

3.

In the 'HA Secure File Transfer Port' field, type the local port number for secured communication.

4.

Click Apply, and then restart the device with a burn-to-flash for your settings to take effect.
