📌 VLANs & Trunking 101: A Deep Dive for Nerds
Access and Trunk mode is a way to organize and manage computer networks.
Imagine you have two computers (A and B) that are connected to a switch. This switch is responsible for connecting these computers to each other and the internet. By default, both computers are part of the same network (VLAN 1) and can communicate with each other and the switch.
Now imagine you want to separate these two computers into their own network. To do this, you create a new VLAN (VLAN 10) and give it a name, such as "PC". You then add both computer's ports (0/1 and 0/2) to this new VLAN. This means that the computers are now part of their own network and can only communicate with each other and not the switch.
But what if you want these two computers to be able to communicate with each other even though they are on different switches? To do this, you create a trunk link between the two switches. This trunk link allows the computers to communicate with each other even though they are on different switches. The trunk link uses a protocol called 802.1Q, which is compatible with most switches.
So, in a nutshell, Access and Trunk mode is a way to manage and organize computer networks by creating different VLANs and using trunk links to allow communication between them.
