In the world of networking, not all switch ports are the same. Whether you're studying for your CCNA or managing a live network, knowing the difference between Access and Trunk ports is essential. Let’s break it down simply 👇
What Is an Access Port? 💻
An Access Port is designed for end-user devices like PCs, printers, and IP phones. It connects directly to the user side of the network and belongs to only one VLAN.Key Features of Access Ports:
- 🖥️ Connects to end devices (PCs, printers, phones)
- 🔸 Works with a single VLAN only
- 🚫 Sends frames without VLAN tags (untagged)
- 📡 Devices share the same broadcast domain
- 🎧 Supports Voice VLAN for IP phones
What Is a Trunk Port? 🌐
A Trunk Port connects networking devices together - like switch-to-switch or switch-to-router links. It carries traffic from multiple VLANs simultaneously using VLAN tagging.Key Features of Trunk Ports:
- 🔗 Connects switches or routers
- 🧩 Carries multiple VLANs at once
- 🏷️ Uses VLAN tagging (802.1Q) to separate traffic
- ⚙️ Each VLAN forms its own broadcast domain
- 🚫 Voice VLAN not supported
Pro Tip 🧠
Use Access Ports for user devices and Trunk Ports for interconnecting your networking equipment. Mixing them up can lead to VLAN issues, IP conflicts, or even complete network outages 🚨 Last edited:
