hanged state to up

*Mar 3 05:22:11 IST: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan102, c

A VLAN interface goes down when there are no physical interfaces left in that VLAN, I suspect that this VLAN only has 1 physical interface in it, which is going up and down.

Thanks for the response, but already 4 PC's are connected on this VLAN, one more info i would like to highlight is, i never assigned any IP address on any of the VLAN interface, but is there any possibility that there might be a cabling issue which is creating problem by making this particular VLAN interface going up & donw?
