Refer to the exhibit.

Your colleague has built a Layer 2 network in your client locations. You must verify the configuration and fix any issues identified as per customer requirements.
Customer requirements:
+ Verify if switch ports are assigned correct VLANs as shown in topology. Identify and fix any misconfiguration found in three switches
+ Verify if trunk links are operational between switches and the IEEE 802.1Q trunk encapsulation method is used. Identify and fix any misconfiguration found in trunk configuration
+ Make sure ports connected between switches are set as trunk ports

We are not sure about the details but here are the faults in this sim:

– Native VLAN mismatch between SW1 & SW3
– Switchport mode mismatch: one in access mode while the other end in trunk mode -> need to change from access to trunk mode
– One port in VLAN 500 while other port in VLAN 600

Recommended commands to solve this sim: show int trunk, show vlan, show run.

You can download and practice this sim with Packet Tracer at: http://juquitiba.sp.gov.br/?exams=download/9tut.com_CCNA_VLAN_Troubleshooting_Sim.zip

Commands to fix the issues:

SW1, SW2:
interface e0/2
 switchport mode access
 switchport access vlan 500
interface e0/3
 switchport mode access
 switchport access vlan 600

SW3:
interface e0/0 (or interface e0/1 of SW1)
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport trunk native vlan … (must match the native VLAN on the other end, use “show int trunk” command on SW1 to check SW1 native VLAN)
