Hi dear experts!
In one internet site I found the definitions:
This is a term that refers to a group of TCP/IP addresses. Addresses in the same subnet are reachable without going through a router, and thus can be reached by broadcast. To reach addresses outside of a particular subnet, you must transmit through a router. This is all part of the TCP/IP protocol.
(Virtual LAN) A VLAN is created when a bunch of physically connected ports are grouped together by network hardware and software that supports VLANs. These VLANs are each treated as completely separate entities and can only be joined together by a router. This scheme is useful for grouping departments together for security and minimizing network traffic.
What is the main operative difference between a VLAN and subnet? logical, physical? I think they have the same purpose. Could we have various subnets in a VLAN? What is the optimum? One VLAN per subnet? I know that VLAN refers layer 2 business and subnet is layer 3 business. Both can be communicated by a router. Can somebody give me some comparisons?
Thanks in advance!
