VTPv3 Sim

February 11th, 2017 in Lab Sim Go to comments

You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.


Question 1


To comply with the configuration of other switches, we need to get VTP configuration of Sw1 or Sw2. On Sw1 use the “show vtp status” command:


From this output we learn on Sw1:
+ VTP is running version 3
+ VTP Domain is “CCNP”
+ Sw1 is the VTP Primary Server (we will explain about Primary Server later. Now just understand it is in VTP Server mode)

So on the New_Switch, the VTP Domain must match. New_Switch should run VTP version 3 if if can (but it is not a must as VTP version 2 is compatible with VTP version 3). The New_Switch is connecting to hosts so it is in Access Layer so it should be configured as a VTP Client (although Transparent mode is acceptable) so there are only two suitable choices D & E.

From the exhibit, the New_Switch is connecting to a host in VLAN 100 so its E0/0 interface should be in VLAN 100 -> only D is correct.

Question 2


On Sw1 & Sw2 we can check with the “show interfaces trunk” command:



Sw1 & Sw2 are connected through E2/3 & E2/3 so we can see the native Vlan on these trunks are 99. We should check both Sw1 & Sw2 to see if the Native Vlan on both sides match.

Question 3


Use the “show vtp status” on SW1 and SW2 we notice both of them are in “Server” mode so we should choose: A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2.

In practical we only need to create VLANs on one of the “Server” switch and these VLANs will be propagated automatically to others “Server” and “Client” switch. But maybe it is not the answer Cisco wants (as it makes both answers B & C are correct).

Question 4


To configure private VLAN we have to change VTP (even version 3) to Transparent mode. In fact, to disable VTP pruning on Sw4 (in Client mode) we also have to change to VTP Transparent mode so answer C can be understood as “change SW4 to Transparent mode” so it is the best choice.

Note: Unlike VTP version 1 and 2 in which VTP pruning is enabled on VTP Server only, VTP version 3 requires VTP pruning must be enabled on all the switches in the VTP domain so we can also disable VTP pruning on each switch separately. Here is the link for your reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swvtp.html

“With VTP versions 1 and 2, when you enable pruning on the VTP server, it is enabled for the entire VTP domain. In VTP version 3, you must manually enable pruning on each switch in the domain.”

    Q3 & 4 are nasty! Cisco always seems to throw a curve ball in one of the lab questions.

    I’m no expert but I think:

    Q3 is B. ‘Configure VLAN 500 & VLAN 600 on SW1 only’. This is VTPv3 and SW1 is the primary server.

    Q4 is A. ‘Disable VTP pruning on SW1 only’. VTP Pruning is not compatible with PVLANs in VTPv3 (see below link). You can create PVLANs in server mode as well as Transparent mode in VTPv3, so it makes sense to create them on the primary server, SW1, where they will be propagated to SW4 and not have to change any of the switches to Transparent mode.

    I took the exam today and passed. I had this sim and am still none the wiser to whether Q3 or Q4 where correct.

    In the sim SW1 and SW2 where both VTPv3 Servers for VLANs (not Primary) and Transparent for MST. Both SW1 and SW2 had a Primary Description of SW1 but the Primary Device ID given did not exist on any of the switches. SW4 was set to ‘Client’

    I made the assumption that is SW1 & 2 where Transparent for MST then the answer to Q3 was A ‘Configure VLAN 500 & 600 on both SW1 & SW2’

    As SW1 and SW2 where both VTPv3 Servers for VLANs (not Primary) I made the assumption that the “best” answer to Q4 was A ‘Disable VTP pruning on SW1 only’.

    I may not be right but hopefully it might shed more light on the question for others!

    @1WAY how you answered the questions 3 and 4? Do you received a complete score for those questions?

    @Good question from Lunchi,

    I answered as stated in my previous reply. Scoring is not detailed enough to tell you whether you are right or wrong on any one question, It’s given as percentages in two categories. I don’t know If I was right or wrong?

    VTP3 feature have primary and secondary servers. A primary server take control of domain. Secondary servers are as a client. According the picture answer is B.

    Look on post from 1WAY February 20th, 2018

    “Q3 is B. ‘Configure VLAN 500 & VLAN 600 on SW1 only’. This is VTPv3 and SW1 is the primary server.” If you try to create Vlan on SW2 you will see:
    “Sw2(config)#vlan 501
    VTP VLAN configuration not allowed when device is not the primary server for vlan database.”

    “Q4 is A. ‘Disable VTP pruning on SW1 only’.”
    If you try to configure private-vlan on VTPv3 with enabled pruning you will see:
    “Sw1(config)#vlan 300
    Sw1(config-vlan)#private-vlan primary
    %Private VLANs can only be configured when VTP is in transparent/off modes in VTP version 1 or 2 and in server/transparent/off modes in VTP version 3 when pruning is turned off”
