Solving the Problem
Different problems require different actions and solutions, but follow these basic steps
to fix any problem:
1. Identify the course of action and the steps you plan to take.
2. Decide what tools are necessary to fix the problem on the network. For example,
you can use the CLI as a tool to look at events and set SNMP traps. You can use a
cable tester to check physical media connections.
3. Perform each step for the course of action.
4. Verify the result of each action using the available CLI show commands. For
example, if you enabled a port, use the appropriate show ip interface brief
command in Privileged EXEC mode to verify that the port is enabled.
5. If more than one possible action exists, select the easiest one first to quickly
eliminate possibilities, or select the action that appears most likely to solve the
problem first, even if it is the most time-consuming or difficult to perform.
Evaluating the Solution
Once you find the solution, test it to ensure that no new symptoms or problems occur.
If new symptoms or problems do occur, repeat the troubleshooting process to
determine the cause. If problems or symptoms recur, create a standard test plan to
evaluate fixes.
