The change-dns-ip-fqdn option changes the DNS configuration. When using this command, you must enter the DNS IP address, and you can optionally include the DNS FQDN (shown as [FQDN] in the examples). Depending on whether you have just a single server or both primary and secondary servers, you can use the command to make the following changes:
  • Change primary only – first two methods shown in the examples
  • Change primary and secondary
  • Change secondary only
  • Remove secondary – used when you have both a primary and secondary and you only want to retain the primary system
  1. Log in to the Avaya SBC CLI using administrative privileges.
