In which situation will need to disable the management contorl in port setting?
If you discover a loop in VLAN 1 on a particular port, despite being certain that VLAN 1 is not configured on that port and considering that the management port is also assigned to VLAN 1, the solution is to deactivate the "management control" in the port settings.

Why my LACP connection is not up?
If your Link Aggregation Control Protocol (LACP) connection is not coming up, it could be due to several reasons. Here's a checklist of things to consider and troubleshoot: LACP Configuration Matching: Ensure that LACP is configured consistently on both ends of the link. The LACP mode (Active or Passive) and key must match…

How to use port mirroring in Nebula
Port mirroring is a feature that allows you to copy and send network traffic from one port (or multiple ports) on a switch to another port, often used for monitoring or analyzing network traffic. In Nebula, the steps to configure port mirroring may vary slightly depending on the specific model of your Nebula switch. Here's…

Why the switch has disconnected from the NCC after changing the management VLAN?
When a switch disconnects from the Nebula Control Center (NCC) after changing the management VLAN, several factors may contribute to the issue. Here are the potential reasons and troubleshooting steps: VLAN Tagging: Ensure that the switch ports connecting to the Nebula Control Center and other relevant network devices are…

What is difference between switch port media type SFP+ or DAC10G?
The port settings for SFP+ and DAC are adjusted based on different types of devices to achieve optimal performance with suitable signal strength. It's possible to see that a transceiver connected to a media type "DAC10G" port also works. The reason is that both options have the same signal interface; however, it's…

How to check if the transceiver DDMI is within the normal working range.
To check if a transceiver's Digital Diagnostic Monitoring Interface (DDMI) is within the normal working range, follow these general steps: Access Transceiver Information: SSH to switch and use the command-line interface (CLI) "show interfaces transceiver" Identify DDMI Parameters: Look for DDMI-related parameters in the…

Voice VLAN on Nebula.
ackground: Voice VLAN is a feature that separates voice and data traffic on a network, ensuring optimal performance for voice communication. This is particularly important for VoIP (Voice over Internet Protocol) systems. In this guide, we will walk you through the steps to configure Voice VLAN on a Nebula switch. Topology…

Why does my switch show STP blocking on the port connecting with the other switch?
The nebula switch enables RSTP to prevent a loop in the ring topology by default. If your topology is a ring topology, one of the ports will be blocked by RSTP. If the ring topology is not your expected topology, please check your connections. If you set LACP but the connecting device hasn’t set LACP, Nebula will show…
-
Can I connect LACP ports before set up LACP?
It is recommended not to connect LACP ports before setting up LACP or your network will cause loops. However, if you have already enabled RSTP on both switches, you can set up LACP later. This is because if the switch does not receive the LACP probe packet, the ports will be blocked and won’t cause a loop. However, if you…

Why cannot I configure LACP/static trunk on my switch?
Nebula LACP/static trunk has some restrictions to prevent connection problems. Here's the rules: Normal ports can aggregate with normal ports, but they cannot aggregate with combo ports. Offline combo ports can aggregate with offline combo ports only. Online combo ports can aggregate with online combo ports and the same…

How does Access Mode work in Nebula Switch VLAN, and when should I use it?
Access Mode in Nebula Switch VLAN is used on ports where you know that the connected end devices are not VLAN-capable (e.g., desktop PCs).
-
What is the difference between Trunk Mode and Access Mode in Nebula Switch VLAN setup?
Trunk Mode and Access Mode in Nebula Switch VLAN refer to different methods of configuring VLAN memberships on switch ports. Trunk Mode is used when you have a VLAN-capable device on the peer side and allows for both tagged and untagged traffic. Access Mode, on the other hand, is used on ports where connected end devices…
-
In Nebula Switch VLAN configuration, why is the PVID important for VLAN memberships?
The PVID in Nebula Switch VLAN configuration is crucial as it determines the VLAN membership for untagged traffic on a port. It must match the VLAN you intend to assign to untagged traffic. For example, setting the PVID to 1 means that untagged traffic on that port will belong to VLAN 1.
-
How to setup Nebula Switch VLAN configuration?
Introduction If you are familiar with VLAN according to 802.1Q, you might already be familiar with terminology such as "PVID", "untagged Membership", "tagged Membership" and VLAN-Tag etc. However, more and more networking devices show in their VLAN setup terms such as "Trunk", "Trunking", "Access" etc., which causes…

How can I enable VLAN trunking for my Nebula switch?
Select the “Trunk” type and allow VLANs “all” in port settings page. In addition, this configuration also serves as the default setting for the Nebula switch.
-
What port type should I choose for connecting an end device?
Select the "Access" type and Management control "disabled" in port settings page, as it enables the port to handle traffic for a single VLAN only. Any frames received on this port will be tagged with the port's VLAN ID.

How to Configure Link Aggregation on Nebula switch?
Background: Link aggregation, also known as port trunking or bonding, allows you to combine multiple network interfaces into a single logical interface. This technique enhances network performance, provides redundancy, and improves overall bandwidth utilization. Zyxel networking devices offer robust link aggregation…
