Q & A set of IT experts based on D-LINK Switch configuration

IT experts based on the D-LINK Switch configuration Q & A set, now there is a huge controversy about the configuration of the D-LINK switch, there may be people do not know how to configure the D-LINK switch, IT doesn't matter, after reading the following parameters, you will become an expert.

Company's existing network pattern: All in a network segment, Now IP address is not enough, new purchase of a D-LINK3308TG three layer switch, want to transform the network, do not know how to set the three layer switch to achieve! Please take a look.

The D-LINK Switch configuration method is found on the Internet, but the physical connection is the same. The L3 switch has six 10/100/Mbps Gigabit copper ports and two GBIC Gigabit ports. All departments should be able to communicate with each other! I 'd better explain it in detail. Thank you!

Very simple, the simplest way to configure the D-LINK switch is to divide each Department into a VLAN, respectively set 192.168.X. */255.255.255.0 GW 192.168.X.254, then, bind the Department switch to the port of the layer-3 Switch with an IP address 192.168.X.254, route the data packets on the layer-3 switch, and forward the packets to the internal port of the firewall. Then perform NAT on the firewall.

You need to note that all departments are isolated by VLAN, and they are not in the same network segment. Data in all VLANs is run on department switches, data of different departments is then routed on the layer-3. If network production uses WIN2K3 domain management to assign IP addresses through integrated DHCP, how do I configure a D-LINK switch on a layer-3 switch.

Is the IP address insufficient? The company's scale is not small... Isn't such a simple plan ?? Does the company have no IT department? Are you right about solving the problem? If you have a dedicated IT department and have the ability to do IT, will you still ask "How to do IT" here? If yes, he should ask "What's the problem with this ".

Because the previous network structure is relatively simple, and now did not manually configure the D-LINK switch, said ashamed, so you need to help. The method of the Blue Wolf is more detailed. Try it first. Thank you. Based on such a hardware environment, we mainly listen to your opinions and see if there are any reasonable solutions to make the network safer and easier to manage.

It should be a simple vlan division. However, your server is in a separate subnet. If your previous desktop computer uses dhcp, it will be allocated as a vlan. Because it cannot be broadcast across CIDR blocks, the desktop computer can only specify an ip address. This is not the case either. DHCP can also be REALAY. now, modify the DHCP server and assign N network segments, 192.168.X. */255.255.255.0. The IP address pool is exhausted by changing the IP address pool, otherwise, we will not be able to finish the discussion in two days. We will only talk about the solution.

If the layer-3 switch supports dhcp relay, the layer-3 Switch receives the DHCP information and distributes it according to its own department access interface. For example, the D-LINK Switch configuration, the purchasing department is connected to the switch GB-port1, the Department's IP segment is 192.168.1. */255.255.255.0, then you put the GB-port1 on the layer-3 Switch this interface to all DHCP applications.

Only 192.168.1. * The IP address of this segment, and then the IP address of the GB-port1 port is bound to a gateway address such as 192.168.1.254, so that the IP address they get through DHCP should be 192.168.1. */255.255.255.0 GW 192.168.1.254, which is the dhcp relay method of a layer-3 switch.

In short, a layer-3 Switch acts as a "proxy" in the DHCP process. Now the main problem is after the D-LINK3308TG in, a lot of settings, do not know how to set. This switch has six ports. Is each port bound with an IP segment? Don't shoot bricks. I really don't know the layer-3 switch. It's dizzy!

A port is a vlan and an ip address is bound to a vlan, for example, 192.168.1.254. The following machine uses this ip address as the gateway to enable Layer-3 switching routing. Then, the server can communicate with each other, if you don't understand it at all, find an integrator and pay for it. After all, the business is the most important.
