Figure 3.23 Troubleshooting scenario

In this first scenario, a manager calls you and says that he cannot log in to Server1 from PC1. Your job is to find out why and fix it. The Cisco objectives are clear on the troubleshooting steps you need to take when a problem has been reported, and here they are:

Check the cables to find out if there's a faulty cable or interface in the mix and verify the interface's statistics.

Make sure that devices are determining the correct path from the source to the destination. Manipulate the routing information if needed.

Verify that the default gateway is correct.

Verify that name resolution settings are correct.

Verify that there are no access control lists (ACLs) blocking traffic.
