DHCP server is a function that is available in DrayTek layer 2+ Vigorswitches. The DHCP server only needs to configured on the core switch and this will also help to reduce the workload on the main Internet router. It will continue to privide DHCP services even if the router is offline. Devices connected to edge switches will also be assigned an IP address from the core switch. In addition the Bind IP to MAC function can also be used to assign a static IP address for important devices.
Go to Switch >> VLAN Management >> Create VLAN
Go to VLAN Routing >> Interface Settings
Go to Switch LAN >> DHCP server >> DHCP server Settings
The status will now become Grenn Light showing Server is running
Once the DHCP server is configured in the VigorSwitch you are ready to test it by the following procedure Go to Switch LAN >> VLAN Management >> Interface Settings
You can connect a PC to VigorSwitch and capture the packets to verify DHCP is working correctly
As we can see, 192.168.100.2 responds to the DHCP discover packets and get the PC an IP address.
DrayTek layer 2+ Vigorswitches also support the Bind IP to MAC feature. This can be used to reserve LAN IP addresses for certain devices. With the DHCP server and Bind IP to MAC features, we could have a strengthening control in network.
Go to Switch LAN >> DHCP Server/Relay >> Bind IP to MAC
