Is a VLAN a subnet?
At a high level, subnets and VLANs are analogous in that they both deal with segmenting or partitioning a portion of the network.
However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network..
What is the difference between VLAN and LAN?
LAN stands for Local Area Network is a group of network devices which allow the communication between connected devices. On the other hand VLAN stands for Virtual Local Area Network which is used to enhance the performance of LANs (Local Area Networks).
How can I see VLAN trunk?
Use the show interfaces trunk command to check whether the local and peer native VLANs match. If the native VLAN does not match on both sides, VLAN leaking occurs. Use the show interfaces trunk command to check whether a trunk has been established between switches. Statically configure trunk links whenever possible.

Should I use VLAN or subnet?
99% of the time, a subnet should be equivalent to a VLAN (i.e. each access subnet should map to one and only one VLAN). If you have hosts from more than one IP subnet in the same VLAN, you defeat the purpose of VLANs, as the two (or more) subnets will be on the same broadcast domain.
