Configuring Authentication for the Controller and NTP Server

Configuring Authentication for the Controller and NTP Server

Information About Configuring Authentication for the Controller and NTP Server

Starting in release 7.0.116.0, the controller software is now compliant with RFC 1305. As per this requirement, controllers must synonymize time with an NTP server by authentication. By default, an MD5 checksum is used.

Configuring the NTP Server for Authentication (GUI)


    Step 1   Choose Controller > NTP > Server to open the NTP Severs page.
    Step 2   Click New to add a new NTP Server.
    Step 3   In the Server Index (Priority) text box, enter the NTP server index.

    The controller tries Index 1 first, then Index 2 through 3, in a descending order. Set this to 1 if your network is using only one NTP server.

    Step 4   Enter the server IP address.
    Step 5   Enable or disable the NTP Authentication.
    Step 6   If you enable the NTP Authentication, enter the Key Index.
    Step 7   Click Apply.
