I have the following situation: In one of the rooms at home, I have a TV with a set-top box, along with some other network devices. All other devices should be behind my router in the local network LAN.
Unfortunately I have only a single ethernet cable going to the room. The result is that I can no longer access the switch management interface, because I don't know it's IP address.
I'm not sure, but I suspect the switch has received an IP address directly from the cable modem instead. This is of course not supposed to happen. For now I worked around this problem by assigning a static IP address. But how can I be sure the switch can't be accessed from the internet? Because that would be a huge security risk! How do I restrict this to only devices inside the LAN? The switch management interface is painfully slow, to the point where it is simply unuseable.
The strange thing is that if I disconnect the cable modem from the main switch, those high ping times immediately disappear and the management interface becomes responsive again. To me, that seems to indicate a problem with the switch or its configuration. If your modem can be a router, it means that the switch will get the private IP address even if get the IP from the modem, then you don't need to worry about that other people can access your switch.
Because they cannot access the private IP address. Bug if your switch get the public IP address, then it's recommended to change to static private IP adderss. And your switch model doesn't support management VLAN, so cannot meet the demand that only allow the device from LAN to access the switch.
Your switch model still support managed by utility. You can use utility to scan the switch for confirming its IP address. The utility can be downloaded from TP-Link website.
If your switch is using private IP address, the high ping delay is abnormal. Unless your traffic is too much to make the netowrk slowly. The cable modem does not contain a router.
The high ping times are not caused by high traffic, because I also see it when the network is almost idle. If the switch management interface can indeed be accessed from all vlan's, then that's a huge security risk! If that's not possible then it's worthless to me. I consider being able to configure the management vlan basic functionallity for a vlan capable switch. Even if the high ping times do not affect the normal traffic forwarding, it is still problematic because it means I can't configure the switch.
If I needed a switch without configuration, then I would have bought a unmanaged switch. High cpu usage is probably also a good indication that there is something seriously wrong with the switch! For testing, I replaced it with the TL-SGE switch with the exactly the same configuration, and that works just fine. Normal ping times and the management interface is very responsive.

How to configure 802.1Q VLAN on TP-Link Easy Smart/Unmanaged Pro Switches?
The ports with the same Admin Key will be aggregated to the same group. Leave the port priority as default. A lower system priority value indicates a higher system priority. When exchanging information between systems, the system with higher priority determines which link aggregation a port belongs to, and the system with lower priority adds the proper ports to the link aggregation according to the selection of its partner.
There are two modes of ports: Active and Passive. It is suggested that set one side as Active mode and the other side as Passive mode. The configuration process is basically the same as above. Check port 22, 23, Then click Apply. Since the lines are aggregated or disaggregated dynamically into the group, when we connect three corresponding ports, port will become member ports of LAG2 for TGTS.

In the Global Config page there is Hash Algorithm setting. When packets are forwarding to a LAG, switch performs Hash Algorithm operation on source and destination MAC address of each packet and according to calculation results selects corresponding port for data forwarding. Get back to example we mentioned above. And LAG2 includes port 22, 23, 24 as member ports. On UNIT1 we could configure port 22, 23, Get products, events and services for your region.

This review covers the 24 port JGSEv3 model. Plug it in, connect network devices, and go. No problems. This switch runs some management software and has a default password. If you know that password, you can change switch configuration from any device connected to any port. There's even a handy utility to help you find these switches on a network. Moral of story: change the password if you don't want folks messing with your switch.
If this switch is connected to an open internet connection, you run the risk of having people on the internet manage your switch. Add to cart. It is operating perfectly including one VLAN in the client's configuration as their primary switch. Bottom Line: this is a dependable switch that handles all the clients throws at it. I only use the Smart Control Center software for initial setup of the IP address and changing the default passwords a very good idea if you care about security.
After that I use the built-in web GUI. A set of rack mount ears and hardware are Only 6 left in stock more on the way.
I have had this switch in my garage for almost two years for surveillance cameras and it gets hot in there the garage is not cooled.
I lost connection to two cameras yesterday when it was over degrees outside and determined the switch was the issue.
I went to my sweltering garage and that was when I saw that sunlight was shining directly on the switch through a window. I touched the switch and it was very hot. It was absolutely baking - I wish I had a thermometer. I could not believe it was functioning at all. I moved the switch out of the sunlight and let it cool overnight. I checked my cameras this morning and all were working. I had expected this switch to fail the first summer it was in the garage because of the harsh conditions that it certainly was not engineered to tolerate.
This is a great switch. I've purchased many, many Netgear switches for small businesses and homes over the years. Bought this switch to replace and 8 port and a 4 port Have never had a failure. I find the negative reviews here to be curious -- wonder if they're using cheap patch cables -- I don't scrimp when it comes to cables. Or plastic switch models.
As the following figure shows, the switch connects to two different groups. It is required that the computers in the two groups cannot communicate with each other, but both of them can access the internet via the router. Enable Leave port as untagged ports in VLAN 1.
Note: Only after you enable the In the Add port 1 and port 2 to VLAN 2 as untagged ports. Click Apply. Add port 1 and port 3 to VLAN 3 as untagged ports. By default, PVID of all the ports are 1. As the following figure shows, a company has two groups which connect to two switches.
It is required that the two groups cannot communicate with each other, but both of them can access the internet.
MTU VLAN Configuration
Super User is a question and answer site for computer enthusiasts and power users. It only takes a minute to sign up. New to the network is a Raspberry Pi which will be used by a team for a school project I am working on. Because the Pi is available on the Internet, and also on my home network, I want to segregate it from all my other devices on my network. Effectively, I want the Pi on one side of a fence, and everything else on the other. All devices need access to the Internet.
At first, I tried unsuccessfully to set up two VLANs on my DD-WRT router, but after a day of messing around and forum surfing, it seemed like many people had trouble with firmware bugs. For the life of me though, I cannot get it to work like I'd expect! Quoting the help text in the switch configuration:.
Each VLAN contains two ports, the uplink port and one of the other ports in the switch, so the uplink port can communicate with any other port but other ports cannot communicate with each other. So you could use that and configure port 1 as the uplink port. Unfortunately that also means that ports 2 through 7 cannot communicate with each other.
If you need ports 2 through 7 to communicate, you need to look at other options, because the Multi-Tenant Unit VLAN feature does not appear to be flexible enough to allow that.
That leaves tagged VLANs as your last option. But having a port be an untagged member of more than one VLAN is problematic because untagged frames sent to the switch could be intended for any of those VLANs, and the switch cannot know. Instead what you should do is to make the uplink port to the router be an untagged member of no more than one VLAN and a tagged member of the rest. On the router this will look like two virtual network interfaces connected to the two different VLANs.
Your desired setup is definitely possible on this device. With " My setup, which I had running on exactly this device, was more or less identical to what you would like to achieve. With this configuration, Port 6 and 7 are seperated from each other.
