From the admin console, you can execute basic network troubleshooting commands like arp, ping, ping6, traceroute, traceroute6, NSlookup, and AvgRTTs. These connection tools can be used to determine the network path from the system to a specific server.

Identify the Problem. The first step in troubleshooting a network is to identify the problem.

  • Develop a Theory.
  • Test the Theory.
  • Plan of Action.
  • Implement the Solution.
  • Verify System Functionality.
  • Document the Issue.
