Ehternet Cable Creation (Straight Through and Cross Over)

Hi friends !

I know about the basic and easy concept of cable creation. When creating Straight Through/Cross Over cables, there is a industry standard pattern&

Straight Through Cable

White Green      ----------------------  White Green            1--------1
Green      ----------------------  Green                  2--------2
White Orange---------------------- White Orange            3--------3
Blue      ---------------------- Blue                  4--------4
White Blue      ---------------------- White Blue            5--------5
Orange      ---------------------- Orange                  6--------6
White Brown      ---------------------- White Brown            7--------7
Brown      ---------------------- Brown                  8--------8

Cross Over Cable

White Green      ----------------------      White Orange            1--------3
Green      ----------------------      Orange                  2--------6      
White Orange----------------------      White Green                                 3--------1
Blue      ----------------------      Blue                  4--------4
White Blue      ----------------------      White Blue                                 5--------5      
Orange      ----------------------      Green                  6--------2
White Brown      ----------------------      White Brown                                 7--------7
Brown      ----------------------      Brown                  8--------8

I know about this pattern and I use the same pattern when creating cables. BUT&

Sometimes I dont use this color pattern and I just take a simple memorable pattern like this one&(for straight through)

White Green      ----------------------      White Green
Green      ----------------------      Green
White Orange----------------------      White Orange
Orange      ----------------------      Orange
White Blue      ----------------------      White Blue
Blue      ---------------------      Blue
White Brown      ----------------------      White Brown
Brown      ----------------------      Brown

And when I create cross over, I just replace 1 to 3 and 2 to 6. With cable tester, I find that the cable is OK.

I want to know&WHETHER IT IS COMPULSARY TO USE THE INDUSTARY STANDARD COLOR PATTERN OR I CAN USE MY OWN PATTERN&

I want to know that when I use a switch and connect PCs to switch using cables with industry standard color pattern then they ping and communicate with each other...and to the same switch, I connect a PC using cable with my own color pattern then some times it works and sometimes it doesnt (It shows that it is connected with 100 Mbps bandwidth but it cant access internet while others can through Proxy Server and I have given all proper proxy settings to it as well as to others).

I want to know&WHETHER IT IS COMPULSARY TO USE THE INDUSTARY STANDARD COLOR PATTERN OR I CAN USE MY OWN PATTERN&

I ALSO WANT TO KNOW WHETER I WILL HAVE TO USE THE SAME COLOR PATTERN FOR ALL THE CABLES WHICH ARE CONNECTED TO THE SWITCH OR I CAN USE DIFFERENT COLOR PATTERNS FOR THE CABLES&???

Please reply in this regard.

I will be highly thankful to you.

Thanks&
