check VTP configuration guide :

https://www.cisco.com/c/en/us/support/docs/lan-switching/vtp/98154-conf-vlan.html

Note : if you already have VTP Server you try to configure another VTP Server that create a issue - make sure check the guide lines before you enable VTP.

Finally VLAN is up and client getting IP from switch. But urfontunatley switch ip is not pinging from any other switch and switch not pinging core ip same as switch not pinging its default gateway. Any idea ?

Can you post show run config for core and access switch?

[deepikarachala92]

You have enabled VLAN 1 SVI on access switch, but other VLANs 100, 102-105 which were allocated on trunk link were not found in running config. Please do check SVI configuration properly on both access and core switch.

What model switch are you using?

[ziyadps]

SGS-350

[ziyadps]

Acces switch cbs 350

Looks like VTP is not supported on that model switch , however you can use GVRP they almost the same technology.

Our core support VTP and we made VTP server. Should we configure gvrp on core and access ? How we can configure GVRP?

[ziyadps]

I have gone thorugh may search i found something that sgs 350 amd cbs 350 doesnot support VTP configuration. My question if its not suporting does it will sunchronize vlan from core ? By default which vtp mode cbs 350 and sgs 350 will act ?

Hello ziyadps,

VTP is not supported by SG300 switches. VLAN propagation from Sg300 to Core Switch is not possible .GVRP concept is totally different compare with VTP. GVRP only send information about the VLANs to its neighboring switches(which supports GVRP).

Reference: https://community.cisco.com/t5/switches-small-business/how-to-configure-both-gvrp-and-vtp-to-work-together-on-small/td-p/2549771

However, you can setup GVRP between two same SGS-350 switches....Please go through the following link:
