 What is VTP (VLAN Trunking Protocol) and Why It Matters in Large Networks In modern enterprise networks, scalability and consistency are critical—especially when managing VLANs across dozens or even hundreds of switches. Traditionally, VLANs are configured locally on each switch, which makes the process slow, repetitive, and error-prone. This is where VTP (VLAN Trunking Protocol) comes into play. ✅ What is VTP? VTP is a Layer 2 messaging protocol developed by Cisco to centralize the management of VLAN configurations . Instead of logging into each switch to manually add or delete a VLAN, a network admin can do it once on a VTP Server switch, and the changes automatically propagate to all VTP Clients within the same domain. 🧠 Why is VTP Useful? Imagine managing 100+ switches. Without VTP, every VLAN change would require manual updates on every device. With VTP, a single change can be distributed network-wide. This reduces: Configuration time Human error Inconsiste...
