ZYXEL GS1920-24HPV2 (01) PDF MANUAL
To learn about tagging, read about IEEE The USG manual gives a few pages to vlans, and no examples, which is a shame, because good examples will help people learn.
Before discussing vlans, I need to define the term interface. The router has four Ethernet ports for LANs, but none of these is an interface — interfaces are associated with ethernet port roles, each of which is associated with one or more ethernet ports.
It seems like these roles cannot be changed but you can rearrange the ports to be in different roles. You can create a virtual interface that will appear at another IP address within the lan. In Linux these used to be called aliases, and they have names like lan The interface connecting a vlan to the router is the vlan interface.
The basic rule of vlans is that one interface can have multiple vlan interfaces. So, if you have the default setup for the ethernet ports P3 — P6, the interface lan1 is on ports P3 and P4, and they are basically connected like a switch, in hardware.
You can add one or more vlan interfaces to lan1. Suppose we had two vlans on our switches, and they uplinked via port P3. You would set up two vlan interfaces, vlan1 and vlan2. Vlan1 would have an ip address, e. Vlan2 would have a different ip address, e. A vlan cannot span two interfaces. By definition, a vlan is just like a lan; a lan has one address on the router. The router then routes traffic between lans. An unusual setup is to have two distinct IP lans on a single switch.
In that setup, the two IP lans cannot talk to each other. At least one of the networks would have static addresses. The vlan interface has an IP address, and all the vlan traffic can communicate only with that IP address. The whole point of having vlans is to mitigate the effects of broadcast traffic. So use the vlans feature to create two separate IP lans, one per vlan.
VLANs and uplink at the switch Remember, at the switch, make the uplink port a tagged port a vlan trunk in Cisco terminology , so the uplink connection to the router will pass all the vlans traffic to the router. Read this to learn a bit about the differences in terminology between Cisco and the VLANs everywhere, or just some places?
The only problem is, there might not be adequate wiring to do this, as some things have changed between the planning phase and execution phase, as usual. And even if it does — will passing that much traffic burn out the ports? So now I have to contemplate using two physically separate networks. The big pain in the butt is that now, if I put a node on network 1, it cannot participate in network 2, and vice versa.
Optimizing Multicast Rate for Home Use
We have written an easy to use and understand guide of how multicast tx rate works so that you can have a better understanding of when and how to use it. In general, the multicast rate in router settings is the same with most of the major brand routers such as Motorola, Asus, netgear, airport, and more.
However, they do not really do a good job at explaining the best way to set it up. Please note that many of the existing articles written or forum discussions about multicast can be a little deceiving with how they are written.
They are either outright wrong, or misphrased in ways that can be considered as wrong and be misunderstood easily by most average users. First, multicast rate options by itself does NOT affect the actual range of your router and wireless network.
For example, if you have 1 devices that are outside the range of your router, having lower multicast rate will NOT magically extend the wireless range of your router. The reverse is true, having higher multicast rate will NOT shrink the range of your wireless network. Second, multicast rate will not affect the level of wireless noise nor interference, nor your wireless signal strength, quality, maximum speed, or minimum speed. Changing multicast setting will not affect any of those wireless characteristics.
This is what multicast rate does, it will however improve the overall performance of your network when used at the right time and right places. Now we will go into what multicast rate actually means and how it can impact your home wireless network. You can check for more details at the wikipedia for IP multicast. Without the tech speak and mumbo jumbo, it basically means that your router combines multiple messages and instead sends 1 jumbo message to multiple devices.
The multicast rate determines how big that jumbo message can be. The benefit of higher multicast rate is to lower the amount of wireless collisions that your wifi data may have. The biggest effect is seen only when you run multiple media streaming devices or services at the same time. Lower mbps value will typically benefit your normal web uses like browsing or file loading. In this case, You should turn off or disable IGMP Snooping and set the multicast rate to be fixed at the lowest value possible.
Some routers have the lowest value as 1mb, 2mb, or 5mb. Imagine two scenarios: Your router is located in your living room and a You have a single laptop in your bedroom.
In this case, the scenario b will benefit from higher multicast settings. However, too high of a multicast rate can hinder the performance of your laptop inside the bedroom, as the multicast will take away the available bandwidth. The only time you should optimize and test different optimal multicast rate settings is when you run multiple streaming devices simultaneously in your home. Some of the multiple streaming services example include but not limited to multicast required services like IPTV, or content streaming around your house with multiple airspeakers.
If you want to experiment with the best fixed values, set the rate setting to around the middle or medium of the spectrum first, then modify the mbps numbers as you experience your wireless network performance. Increase the value if media streaming is having issues, and lower the value if your computer web surfing is having performance issues.
The reason is that higher multicast rate can hinder your individual internet usage by sacrificing it to boost your wifi network streaming throughput. However, setting it too low can cause your streaming devices such as AirPlay to drop connections when the usage gets high. Relevant Multicast Rate Information.

Some routers have the lowest value as 1mb, 2mb, or 5mb. The firmware on each Switch is identified by the firmware trunk version, followed by a unique model code and release number in brackets. For example, 4. Key feature differences between Switch models are as follows. Other features are common to all models The following table describes the PoE features of the Switch by model.
ZyXEL ZyWALL USG-50 VLANs
The Switch can be used standalone for a group of heavy traffic users. In this example, all computers can share high-speed applications on the server. To expand the network, simply add more networking devices such as switches, routers, computers, print servers etc. Figure 1 Backbone Application 1. It can alleviate bandwidth contention and eliminate server and network bottlenecks.
All users that need high bandwidth can connect to high-speed department servers via the Switch. Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location. In the following example, use trunking to connect these two networks.
Switching to higher-speed LANs such as ATM Asynchronous Transmission Mode is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.
The Switch can provide the same bandwidth as ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other.
Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group s unless such traffic first goes through a router. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to other VLAN groups too. This is recommended for everyday management of the Switch using a supported web browser.
See Chapter 4 on page See Section Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 43 on page ZON Utility is a program designed to help you deploy and perform initial setup on a network more efficiently.
See Section 7. With the NCC, you can remotely manage and monitor the Switch through a cloud-based network management system. See Section 8. Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration.
See the Installation Requirements sections in this chapter to know the types of screws and screw drivers for each mounting method. Failure to use the proper screws may damage the unit.
See Table 1 on page 20 for the comparison table of the hardware installation methods for each model. To start using the Switch, simply connect the power cables and turn it on. Do NOT put your hands on it. You may get burned. This Switch is not suitable for use in locations where children are likely to be present. These rubber feet help protect the Switch from shock or vibration and ensure space between devices when stacking.
To make sure of air circulation, do NOT remove them. Figure 5 Attaching Rubber Feet 4 Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the connected cables.
Make sure there is a power outlet nearby. Note: Make sure that you meet the requirements of clearance when you use the Switch for stacking. See Table 1 on page 20 to see whether your Switch has fans. Do NOT block the ventilation holes nor store things on the Switch. Allow clearance for the ventilation holes to prevent your Switch from overheating.
Overheating could affect the performance of your Switch, or even damage it. Follow the steps below to mount your Switch under a table. Figure 6 Attaching the Mounting Brackets 2 Using a 2 Philips screwdriver, install the M3 flat head screws through the mounting bracket holes into the Switch. Proceed to the next section.
See Section 2. The washers should be in between the M4 flat head screws and the brackets. You may need screw anchors if mounting on a concrete or brick wall. Be careful to avoid damaging pipes or cables located inside the wall when drilling holes for the screws. Push the anchors into the full depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave a small gap rdp shop about 0.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all the way in - leave a gap of about 0. Hang the Switch on the screws. Note: Make sure there is enough clearance between the wall and the Switch to allow ventilation. The Switch should be wall-mounted horizontally, and make sure the front panel is facing down.
The Switch's side panels with ventilation slots should not be facing up or down as this position is less safe. Follow the steps below to mount your Switch on a standard EIA rack using a rack-mounting kit. Take all necessary precautions to anchor the rack securely before installing the unit. Figure 8 Attaching the Mounting Brackets 2 Using a 2 Philips screwdriver, install the M3 flat head screws through the mounting bracket holes into the Switch.
Note: Make sure you tighten all the four screws to prevent the Switch from getting slanted. The SFP slots have priority over the Gigabit ports.
Note: The dual personality ports change to fiber mode directly when inserting the fiber module. When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto- negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. A transceiver is a single unit that houses a transmitter and a receiver.
The Switch does not come with transceivers. You can change transceivers while the Switch is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
Check the LEDs to verify that it is functioning properly. Note: Do NOT pull the transceiver out by force. You could damage it. View the LEDs to ensure proper functioning of the Switch and as an aid in troubleshooting see Section 3. It prevents damage to the Switch, and protects you from electrocution. Any device that is located outdoors and connected to this product must be properly grounded and surge protected. Follow your country's regulations and safety instructions to electrically ground the device properly.
Connect the ground cable before you connect any other cables or wiring. To connect power to the Switch, insert the female end of the power cord to the AC power receptacle on the rear panel.
Connect the other end of the supplied power cord to a power outlet. Make sure that no objects obstruct the airflow of the fans located on the side of the unit. Blinking The Switch is returning to the last-saved custom default configuration settings.
