Objectives

Part 1: Locate Network Problems

Part 2: Implement the Solution

Part 3: Verify Network Connectivity

Scenario

In this activity, you will troubleshoot connectivity problems caused by improper configurations related to VLANs and inter-VLAN routing.

Part 1: Locate the Network Problems

Examine the network and locate the source of any connectivity issues.

  • Test connectivity and use the necessary show commands on to verify configurations.
  • List all of the problems and possible solutions in the Documentation Table.

Documentation Table

Problems Solutions
The G0/1 physical interface is up but G0/1.10 subinterface is administratively down. Implement the no shutdown command to enable the G0/1.10 subinterface.
PC3 is configured with the wrong default gateway address. Change the default gateway on PC3 from 172.17.10.1 to 172.17.30.1
Interface G0/1 on S1 is configured as an access port instead of trunk port Use the command switchport mode trunk to change the interface from access mode to trunk mode
Subinterface VLAN assignments are switched on R1. Issue the no encapsulation dot1q command to remove the incorrect configuration. Then configure the subinterfaces with the correct encap dot1q <vlan> command. Reenter the correct IP address information.

Part 2: Implement the Solutions

Make changes according to your recommended solutions.

Part 3: Verify Network Connectivity

Verify the PCs can ping other PCs and R1. If not, continue to troubleshoot until the pings are successful.
