Points to check

1- vtp ver run in client abd server 

2- md5 digest as I mention above 

3- vtp need trunk to work if 

Show interface switchport 

Show that link between SW not trunk vtp not work

4- use 

Debug vtp event 

In client SW' share output

Hello @hamza-ali 

You sswitch is client vtp ok but in 'Configuration Revision : 0'...

Check vtp domain is exactly the same  _ case sensitive....

Check password also

Check VTP version on server vtp. YOur 3560 is in version 1....

Do you have any uplinks (trunk) UP on that Switch ? 

[hamza-ali]

no password for VTP i just connect my switch to the network it got the configuration VTP Server...
can you please help me out how can i fix this issue

[hamza-ali]

yes i give an uplink to switch for network 

[M02@rt37]

ok @hamza-ali 

Please provide this ouptut:

# show interface trunk

Check on server the vtp version too !

[hamza-ali]

My all the switches works as Client mode

[M02@rt37]

ok...

where is the vtp server on your topology ?

[hamza-ali]

vtp server is my distribution switch

[M02@rt37]

Hello @hamza-ali 

OK, so on that distrib switch, check vtp configuration as its version and MD5 digest.

dear Hamza-ali,

As mentioned by fellow community members above,

Please check if trunk is established between the distribution switch and the 3560 switch. 

please compare output from the following commands on both switches (if possible to also share here)

show interface trunk

show cdp ne

show vtp status

show vtp password

show running-config

show run interface <interface>

best regards
bbb

Not direct trunk...

Please find below topology:
3560 switch> Okay Switch sync with VTP Server > Distribution switch

[hamza-ali]

HI Team,

looking forward for your expert opinion

3560 switch> Okay Switch sync with VTP Server > Distribution switch

What you meaning by this?

There is NSK between two SW or unmanaged SW?
