Introduction to VLANs

Hello Usman

Yes, this will function correctly. Since both ports on both switches are access ports, there is no VLAN information sent in the frames that are exchanged. As a result, communication will occur correctly.

It is a good idea however to keep some sort of consistency on the VLANs on all switches within an enterprise network. In the future, you may want to connect those switches using a trunk. You may want to span a particular VLAN across multiple switches. You would not be able to do so unless the VLAN numbers and subnets match correctly. It can be a time consuming exercise to have to change the VLAN numbers and subnets on L3 switches throughout your network in order to get such a configuration to function. It’s best practice to keep these consistent from the beginning..

I hope this has been helpful!
