You have 10 CISCO switches, how will you find the acting VTP server from the VTP Client switch?

After I did a Show VTP Status, the bottom of the display shows the IP address of the VTP server that updated the VLANS. I then did a Show CDP Neighbors Detail which allowed me to see the IP and Hostname of the neighbors. By matching the IP gathered during VTP Status with the IP in CDP neighbors detail, I was able to see the hostname of the Switch acting as VTP Server.

We can by using the following command on any switch by telnet session or console cable:

to view the VTP configuration information, use the show vtp status command:

at the bottom of the display shows the IP address of the VTP server.

to find out the owner the IP obtained which is the server by typing

show cdp neighbors detail:

which helps to get the IP and Hostname of the neighbors connected 

finally comparing the ip's and we find server switch

By identifying the who is acting as the VTP server out of the10 switch. Take note of the following below:

1. Make sure you issue the command "Show VTP status" for each switch

2. Take note of the VTP client mode and transparent mode switches.

3. Take note of those VTP server switches that has a highest revision number.

4. If you have verified and checked who has the highest revision number. Mark it as the Main VTP server.

5. Once you have identified the VTP server and has the highest revision number. Now, that is your VTP server.

From show vtp mode command you will identify the VTP Server switch.

it simple on client. just enter command **show vtp status* will tell you the last update vlan by server,

-->>VTP servers advertise their configuration to the VTP clients in the same VTP domain -

-->> Clients only get the VLANs advertised by the VTP server.

Its just simple.

show vtp status, should tell you who last updated the vlan configuration - which should be the vtp server.

sw01#Show VTP Status

sw01#Show CDP Neighbors

By matching the IP gathered during VTP Status with the IP in CDP neighbors detail,we can see the hostname of the Switch acting as VTP Server.

If you do not want to use VTP to globally propagate the VLAN configuration information, you can assign a static-access port to a VLAN and set the VTP mode to transparent to disable VTP.

The switch automatically transitions to VTP transparent mode (VTP is disabled). No VTP configuration is required.
