How to Configure Rapid Spanning Tree Protocol (RSTP) on Nebula switch
In this post, we will guide you through the process of configuring Rapid Spanning Tree Protocol (RSTP) on your Nebula switches. RSTP is a network protocol that helps prevent loops in Ethernet networks, ensuring efficient and reliable data transmission. By implementing RSTP, you can enhance network stability and improve…

How to control broadcast storm for Zyxel Switch in standalone mode?
Scenario Sometimes you can find some
PCs flooding packets that occupy the network bandwidth. Broadcast storms occur when too much of the network bandwidth is occupied
by these packets. In this situation, normal
packets cannot transmit smoothly. We can enable Broadcast
storm control to reduce the amount of broadcast traffic…

How to enlarge your bandwidth or enhance your network reliability by link aggregation?
Scenario Nowadays, the size of video and photo are larger and larger. This causes more time to back up your videos and photos to NAS or Data Server. The most common solution is
to setup link aggregation to improve network performance by increasing the
available bandwidth between the switch and other network devices as well…

How to prevent loop for Zyxel Switch in standalone mode?
Scenario Loop occurs as a result of human error. It happens when two ports on a switch are connected with the same cable. When a switch in loop state sends out broadcast messages the messages loop back to the switch and are re-broadcast again and again causing a broadcast storm. If a switch (not in loop state) connects to…

How to apply stacking mode on Zyxel switch?
If you want to apply stacking mode on Zyxel
switch, please be aware of the following instructions: 1. The device must be the same
series of model. 2. The Firmware must be the same
version. 3. The quantity and stacking ports
on Zyxel switch Note:
Once the port has become a stacking port, it cannot be used as a normal port.…

How to sync the configuration to the slave unit in the stacking mode?
After
configuring, remember to write memory or press save button then the
configuration will sync to the slave unit. If users forget to write memory or
press save button, the configuration will disappear once the master down. Note:
For some models that support import certificate (XS3800 and XGS4600 currently),
we will…

How to Configure the Switch to Tunnel Layer 2 Protocol Packets Through Service Provider Network
Zyxel switch models support Layer-2 Protocol Tunneling (L2PT) that allows edge switches to tunnel layer-2 protocol packets through service provider networks. It could be used when customer switches are located at different sites and connected across a service provider network. Therefore, the customer networks can implement…

How to configure ACL to rate limit IP traffic
In some networks, it is necessary to configure rate limits among VLANs. For example, VLAN 10 is for employees within the organization; VLAN 20 is for guests. By rate limiting VLAN 20, we can ensure better bandwidth or network performance for users in VLAN 10. This example shows administrators how to configure ACL to rate…

How to configure bandwidth control to limit incoming or outgoing traffic rate
This example shows administrators how to configure bandwidth control to manage traffic rates. We can limit either incoming traffic, outgoing traffic, or both. In this example, we use two computers: FTP Client (PC) and FTP Server (FTPServer). PC will either be uploading files or downloading files from the FTP Server. Note:…

How to Implement VRRP with Multiple Routing Interface Combine with HA-Pro Using Zyxel Switch
Some companies may only have one ISP and there is only one gateway device connected to it. What if the cable connected between ISP and gateway device is not working or the cable is bitten by a mouse. Or, the gateway device somehow has an abnormal behavior. These situations may cause a single point failure and the customers…

How to configure VRRP to provide hosts with a redundant gateway
This example shows how to configure gateway redundancy. Virtual Router Redundancy Protocol (VRRP) is a feature that allows two gateways to use the same IP address. This allows hosts in the local network continues access to the Internet in the event of a failure on one of the gateways. Note: All network IP addresses and…

How to configure RSTP in a ring topology (V4.70 or previous version)
If your switch firmware version is V4.80, please reference this FAQ The example shows administrators how to set up RSTP (Rapid Spanning Tree Protocol) in the ring topology to implement network redundancy. Note: All network IP addresses and subnet masks are used as examples in this article. Please replace them with your…

How to configure a stacked switch to ensure high server availability
The example shows how to configure a stacked switch to ensure high server availability. In this example, we stack Switch-1 and Switch-2 into one logical switch. By stacking the switch together, even if one switch goes offline, clients can still reach the server. This ensures high availability for servers. This example…

Why WOL is not working with Dynamic Link Aggregation (LACP) on Synology NAS and Zyxel switch?
First, you may need to understand the LACP behavior. If two devices want to build a link via LACP, they exchange LACP packets to confirm each other's status when connected. If they receive the LACP packet form each other, the port status will change to "forwarding" and then start to transfer packets. It means the LACP…

What is hardware stacking?
Hardware stacking is directly connecting Switches to form a larger system that behaves as a single Switch or a virtual chassis with increased port density. (As Figure 1) Usually, the last two ports of your Switch are dedicated for Switch stacking. (Please also check the user guide for details) Figure 1 Switch Stacking…
