Discussion on the Problem of setting D-LINK Switch

Directly hit the netizens on the D-LINK switch settings of the big discussion, in the heated discussion of the netizens, we can master the following involved D-LINK switch settings knowledge, you will have a more easy grasp of the D-LINK switch settings. It will surely surprise you.

Switch in a CIDR Block, Now IP address is not enough, the new purchase of a D-LINK3308TG layer switch, want to transform the network, do not know how to set the D-LINK switch to achieve! Please help.

 

D-LINK Switch Settings: Layer 3 Switch

A: Very simple, the simplest way to set 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.

User 2: 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 can't finish the discussion for 2 days, just say about the D-LINK switch setup 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 settings, the purchasing department is connected to the switch GB-port1, the IP segment of this department 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. A simple understanding of the D-LINK switch settings, the layer-3 Switch acts as a "proxy" in the DHCP process.
