[r.sahney]

Hi Devendra,

            Well looks like you are getting too far without adequate
knowledge at the base.

Since you stated  no body clarifies basics then follow the  steps to
gain total insight -

1 Read Sybex CCNA Study Guide Chapter 2 .
2 Then move on 2 and Appendix on VLANs.
3 Read  http://www.cisco.com/en/US/products/hw/switches/ps4324/products_configuration_guide_chapter09186a00803671e0.html
and Do loads of practicals.
4 Then move on to Cisco press CCNP Switching self study guide.
5 Finally 
http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a0080081042.html

That will give you a lot of information and you will know were to go from here..

Note - WE usually discuss loads of advanced issues on this list, in
case you need any further help let m know off line.

Raja
