Question about Network Accessories
I find this information to be of grate value to me, I have one more question how can I set up a VLAN on a TRT Cat 5e patch panel

A VLAN is a Virtual LAN. It allows the same physical piece of equipment to manage traffic for two separate networks but still block the movement of data between them as if they were not on the same. Picture it like partitioning a hard drive, but your dividing the ports on your switch. As for why, there are a couple reasons. (1) Reducing LAN traffic, every packet sent by a computer has to cycle through every manchine on the LAN, VLAN's limit the number of machines a packet routes through, (2) Security, it also allows you to limit data to a subset of devices or computers. (3) and it allows you to organize your machine on a large LAN by address.
Here are case examples:
1) I want to setup quality of service making sure that servers or phone systems are allotted a certain amount of priority at all times. For example, you wouldn't want your phones to crack and pop because Joe in accounting decided to stream the latest episode of CSI Miami.
2) I want to organize the machines in my organization for security purposes breaking apart different physical networks for each department, building, etc. If you have multinational company running on the same LAN, you don't want everyone pulling from a single pool of addresses.
3) I have a limited amount of equiment so purchase on large switch rather then several smaller ones and divide the ports into specified port groups. I can then set different port restrictions, policies, and quality of service for each group...say an IP phone system, a DMZ, a lab, and management PC's.
