Hi Guys,
I want to clear one doubt, please help on this.
Cisco says," Per-Vlan Spanning tree(PVST) is a Cisco properietary version of STP. Due to its proprietary nature, PVST requires the use of Cisco Inter-Switch Link(ISL) trunking encapsulation between switches.
But I think PVST can be used with the IEEE 802.1Q trunking encapsulation.
Please comment.
Thanks

Hi Amolak
PVST does only work with ISL. PVST+ is an enhancement of PVST that was designed to work with 802.1q.

Hi Amolak,
Cisco developed PVST+ in order to allow running several STP instances (even over an 802.1Q network).
PVST is not supported on dot1q links.
