Network Load Balancing

Wlbs Display Command

The wlbs display command-line command provides much valuable information about the Network Load Balancing host on which it is carried out. It is intended for use in diagnosing problems with NLB configurations. The information comprises the following areas:

Details of the current cluster configuration.
This section includes the current values for the cluster parameters, host parameters, and port rules, and other registry values for the host.

For more information about the cluster parameters, host parameters, and port rules, see Windows 2000 Network Load Balancing Help.
Last 10 event messages.
The output for each message is the output of the event log. Each message is followed by two lines of hexadecimal numbers.

For the sake of brevity, all the event messages but one were deleted from the following sample output.
IP configuration of the host operating system and network adapter.
This is the output of the ipconfig command.
Current state of the cluster.
This is the membership of the cluster as of the last convergence.

The following is an example of the output of the wlbs display command:
