  6. Enter the IP address of the SNTP server from which the Site Director receives its time.

    Specify a host name only if a DNS server is available to the Site Director. Leave the Device Time Servers field blank.

    For Multicast time synchronization, if you add more than one address, the Site Director OAS tries to contact only the first address.

  7. Click OK.
  8. Click Save. The Site Director now requests the date and time from the selected time server and propagates it to all other engines/servers on the site.
  9. Go to Configuring additional multicast time synchronization settings.
