But switches exists on Layer 3 (Network Layer), Layer 4 (Transport Layer) & Layer 7 (Application Layer) as well. So in a glance, we can say as of now, we have Layer 2 Switch, Layer 3 Switch, Layer 4 Switch and Layer 7 Switch. If you have any query in future regarding networking (LANWAN Routing & Switching). So plz feel free to write me on my mail ID : bhupendra_singh007@yahoo.co.in Thanks & Regards, Bhupendra Singh As your question, L2 switch exist on Layer 2 means on Datalink Layer.
