Refer to the exhibit.

VLAN_Troubleshooting_Topology.jpg

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.

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)

    This is what I did on my exam. You may follow it.

    config terminal

    1- access – vlan
    Interface fx/y ( sw1 – sw2 e0/2 )
    Switchport mode access
    Switchport access vlan X
    end

    2- trunk
    Interface fx/y ( sw3 – e0/0)
    switchport trunk encapsulation dot1q
    Switchport mode trunk
    end

    3- trunk – Vlan
    Interface fx/y ( sw1 – e0/1 )
    Switchport trunk native vlan Y ( y is usually 1 )
    end

    Don’t forget to copy run start.

    @9tut Where is the actual sim for this. I am just seeing the answer. Also I am not seeing this on the right side of the page. Are there other sims that you can provide us, and if there are can you put them with the others on the right side of the page?
    Thank you so much this site is great!!!!!!!

    @9tut can you please write the commands for this Switchport mode mismatch: one in access mode while the other end in trunk mode -> need to change from access to trunk mode.

    I am trying to answer this question. Can someone please help in giving me a solution. The issue lies in understanding VLAN setting on SW3 and SW1. Better still if someone can give me PT solution for this would be very helpful.

    Thanks
    Navin
