Security and SD-WAN


Welcome to Integrity Hotel Partners, your trusted partner for all your real estate needs. In this article, we will dive deep into the best practices for native VLAN configuration, focusing on the important aspects related to security and SD-WAN.

Understanding VLANs

Before we delve into the best practices, let's refresh our understanding of VLANs (Virtual Local Area Networks). VLANs allow network administrators to segment a physical network into multiple logical networks, enhancing security, manageability, and flexibility. Each VLAN operates independently, as if it were on a separate physical switch.

Benefits of Native VLANs

The native VLAN is the default VLAN assigned to an interface or trunk port. It is essential in establishing transparent communication between switches and avoiding unnecessary encapsulation or tagging. Using a native VLAN correctly can significantly improve network performance and security.

Best Practices for Native VLAN Configuration

1. Separate Native VLAN for Management Traffic

One of the crucial best practices is to create a separate native VLAN dedicated to management traffic. This ensures that control plane traffic, such as SSH, SNMP, and other management protocols, remains isolated from other user data traffic. By doing so, you prevent potential security vulnerabilities and simplify troubleshooting processes.

2. Disable VLAN 1

By default, VLAN 1 is often assigned as the native VLAN. However, it is recommended to disable VLAN 1 for security reasons. Assign a different VLAN as the native VLAN and avoid relying on VLAN 1 for any critical operations. This practice minimizes the risk of unauthorized access and VLAN hopping attacks.

3. Utilize VLAN Access Control Lists (VACLs)

VACLs are an effective means of controlling network traffic within a VLAN. By configuring VACLs, you can specify permitted or denied traffic based on source and destination IP addresses, protocols, ports, or other criteria. Implementing VACLs helps prevent unauthorized access, restricts communication between specific devices, and enhances overall network security.

4. Implement Port Security Measures

To mitigate the risk of unauthorized access or network breaches, it is essential to implement port security measures. This includes features such as MAC address filtering, limiting the number of allowed MAC addresses per port, and enabling sticky MAC addresses. These measures ensure that only authorized devices can connect to specific switch ports, minimizing the potential for security incidents.

5. Regularly Update Firmware and Security Patches

Maintaining up-to-date firmware and security patches for your network devices is crucial. Manufacturers often release updates to address vulnerabilities, bugs, and enhance overall device functionality. By regularly updating your switches, you ensure that known security flaws are patched, reducing the likelihood of successful attacks targeting your network infrastructure.


In conclusion, native VLAN configuration plays a significant role in network security and seamless communication. By following the best practices outlined in this article, such as creating separate native VLANs for management traffic, disabling VLAN 1, utilizing VACLs, implementing port security, and keeping your devices up-to-date with firmware and security patches, you can enhance the security and efficiency of your network infrastructure.
