I'm getting difficulties realizing a port based VLAN,Say we have VLAN10 (having three end stations) and say VLAN10 is configured to one port(port1) on some Switch(s1).

Now how these three end stations can be connected to port1, physically we required three different links to connect to three different ports but here we connecting or saying three end stations are connecting to port1.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

Do not cross post. You asked this exact same question on SO, where I answered it and told you to read up on these topics before asking any more questions. Go read up on vLANs and come back when you have a specific question. – Chris S Jul 27 '12 at 14:55

Why then not just configure 3 ports on your switch that all use VLAN10?

Your other option is to use a dumb switch and attach it to port1. You can then attach your other devices to this switch.

Do mind that no other vlan must be attached to this switch then (no trunking). Otherwise a problem that will arise is when your frames are at max length, the dumb switch will think the frame is too large (doesn't recognize VLAN tag) and damaged and drop it.

there is any docs where i visualize how Port based LAN's are works – AMIT Jul 27 '12 at 14:02
I think CCNA module 3 covers this quite well – Lucas Kauffman Jul 27 '12 at 14:03
Given that this is an access port and not a trunk port, and given that there is no separate voice VLAN mentioned, would the unmanaged switch that you are proposing ever encounter a tagged packet? I think not. – Skyhawk Jul 27 '12 at 14:44
That's true, I forgot about that :( – Lucas Kauffman Jul 27 '12 at 14:48
