Configure DNS Locator Queries (Oracle ILOM CLI)

A DNS locator query identifies a specific DNS service and the port on which it runs. By default, the switch provides two DNS locator queries, but you can create custom DNS locator queries.

  • The switch supports a maximum of five DNS locator queries.

  • The current DNS service can be changed to a DNS service in a different domain by specifying the new DNS service in the DOMAIN element of the locator string.

  • The current DNS port can be changed to a DNS port in a different domain by specifying the new port in the PORT:x element of the locator string.


Note -  For the switch to support locator queries, the DNS service and DNS Locator Mode must be enabled on the switch. See Enable the AD Client (Oracle ILOM CLI).
  1. Enable DNS locator query mode.
    -> set /SP/clients/activedirectory/ dnslocatormode=enabled
    Set 'dnslocatormode' to 'enabled'
    ->
    
  2. Create DNS locator queries.
    -> set /SP/clients/activedirectory/dnslocatorqueries/X service=service_name.domain.PORT:X
    ->
    

    where:

    • X is a number from 1 to 5 that represents the locator query.

    • service is the locator service name, including a domain and port.

    • domain is the domain that the locator query will search.

    • PORT:x is the port on which the locator query communication occurs.

    For example, to create a DNS locator query 1 for the service _ldap._tcp.gc._msdcs in domain companyq on port 2112, type:

    -> set /SP/clients/activedirectory/dnslocatorqueries/1 service=_ldap._tcp.gc._msdcs.companyQ.PORT:2112
    Set 'service' to '_ldap._tcp.gc._msdcs.companyQ.PORT:2112'
    ->
    
  3. Repeat the preceding step as needed to create the required number of queries up to the maximum.
