Hi Community,

Hi KelvinFu

Yes you want to create DHCP Server on your M4300 Managed switch and assign DHCP Pool for each VLAN with excluded IP address range each time..

The way each DHCP pool is binded to its correct VLAN is simple: the network in each DHCP pool must belong to each VLAN IP interface subnet (or vice versa if you prefer).

So if your VLAN 1 Routing IP Interface is 192.168.100.1 255.255.255.0, then your corresponding IP DHCP Pool <<DHCP_VLAN_1 or any other name>> should have its network such as 192.168.100.0 255.255.255.0

You can refer to M4300 Admin manual and closely follow the example in Chapter 24 starting page 450 using either CLI or Web interface.

You can select excluded IP range for each pool.

All DHCP server parameters (including options) are available in M4300 technical documentation: 

• In M4300 CLI manual, DHCP commands are found page 245
• In M4300 Web interface manual. DHCP commands are found page 84

Hi Kelvin,

Welcome to NETGEAR community！

Which feature or function do you wan to deploy?

I guess the DHCP server function is your requirement.

M4300 support DHCP server and here is the configuration guide for you.

Please reference to Chapter 24 DHCP

M4300 Software Administration Manual (Software Version 12.x)

Regards,

Daniel.
