After the configuration of the domain name system (DNS) server is completed in a new site, the status of the DNS server can be checked by running DSP DNS on the local maintenance terminal (LMT) of the serving GPRS support node (SGSN). A sample output of the command is as follows:

 IP address          Priority   DNS Server name   Status     Recursion available  221.177.202.41       1           master            Faulty     Yes  221.177.202.45       2           slave             Faulty     Yes  (Number of results = 2)

The output of the command indicates that DNS services are abnormal.


Possible Causes

  • The link between the SGSN and the DNS server fails.
  • The configuration of the DNS server is incorrect.
