I am running a Windows Server 2019 as a DC running DHCP. I am running a single scope running through a NIC to handle addresses for our small network. I am being asked to add a second DHCP scope so it can manage IPs on another network using a second NIC already installed to ports on a separate VLAN than the existing one. Our system does not have any routers in it and only uses level 2 network switches Cisco C9300-24Ts.
- NIC #1: 192.168.1.10 [VLAN 10] (Exisiting)
- NIC #2: 192.165.5.10 [VLAN 20] (New)
The existing NIC and DHCP scope work great without an issue. The New Scope I set up for NIC 2 is running but when I connect to ports on that VLAN that that NIC is served from I don't get an address.What am I missing? Did I do something wrong?
These 2 NICs are connected to 2 separate isolated networks.
You need to configure the DHCP relay on your switch to sent the DHCP packets from the new VLAN to your server. You do not need the second NIC involved.
