VLAN Troubleshooting Sim

January 27th, 2018 Go to comments

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

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)

    Passed!… new questions. just use Logic, Labs. ACL1-2, VLAN LAB configuration,
    GRE LAB took about 40mins of the time OMG diff 2 diff questions but I made it !

    many drag n drop,all of them here in 9tut! that helped me to recover lost time ,

    DCHP-RIP sim.

    Good luck

    @ xbr

    How many new questions do you think were there in MCQs??

  19. V.Arvind
    March 11th, 2018

    Hello to all. In this question, only one switch(sw3) needs encapsulation. In sw1 the vlan table shows that the two interfaces(e0/2 & e0/3) are in vlan 600 so one of the interfaces should be in vlan 500. In sw2 the interfaces are assigned opposite or wrong vlans so have to be corrected

    Hello all, this question is a bit common in the coming exams so please prepare nicely and practice vlan especially trunking(if using packet tracer, try with switch no. 3560. in this switch you will encounter with the problem of auto mode and trunking can be done by applying encapsulation method or else the port will not be trunked). Alternately, this question can be solved by following commands:
    1) for sw3:
    int e0/0
    switchport trunk encapsulation dot1q
    switchport mode trunk

    2) For sw1:
    int e0/3
    switchport access vlan 600

    3)For sw2:
    int e0/2
    switchport access vlan 500
    int f0/3
    switchport access vlan 600

    candidates who are appearing or are going to appear in the ccna exam, please try the above commands and then tell the result. Best of luck and effort

    Hello everyone! I was looking for this sim everywhere could not find it! But I came across this lab, very similar and for practice purposes is good enough for me. So I thought maybe someone out there will appreciate this sim too.

    did my exam March 15. Saw up to about 6 new questions. Cant remember all in details due to pressure but I remember drag-n-drop for QOS. I also saw questions that were on CCNP Route dumb. Labs remain same. The topology question with R1 R2 and R3 and two branch routers connected to R1 and then questions about tunnels, RIPv2 etc., remember that ? in one of its questions they tweaked config o deny eigrp formation due to access-list blocking eigrp, beware of that. Otherwise I was surprised to pass with 9XX

    Hello Everyone.

    Just passed my exam today. This sim and Access List Sim 2 was there to configure and other GRE Multilink sim, OSPF Neighbor sim and Access List Sim 1 was there to troubleshoot. A bit of configurations are changed you must be present there with mind to solve these sims. Few of Drag and Drops were new in exam.

    Is any Simulator available for VLAN Troubleshooting Sim?

  42. ninou
    April 10th, 2018

    Please help !!!!!

    What is the configuration between SW1 e0/0 and SW2 e0/1 ? trunk?

    Switchport mode trunk on both ends?

    assalamualaikum and hello everyone, i try to fix

    Q1 – Native VLAN mismatch between SW1 & SW3 :

    1- first check by command (show interfaces trunk on SW3) to see what mismatch discovered message
    SW3# show int trunk

    if the message like this, for example: (Native VLAN mismatch discovered on Ethernet1/1 (600), with SW1 Ethernet1/1) go immediately to SW1:

    SW1> enable
    SW1#conf t
    SW1(config)#interface Ethernet1/1
    SW1(config)#switchport trunk native vlan 600
    SW1(config)#switchport mode trunk
    SW1#copy run start

    And chcek by command (show int trunk) there’s no Native VLAN mismatch between SW1 & SW3

    If i missed something please correct me

    @9tut…when can we see a simulator for this sim and the IP V6 OSPF Sim ?

    This sim appears to be coming up in exams, so need to practice it on something
