2 VLANs and 2 external DHCP on N3048
Hello,
I'm trying to implement a setup where N3048 will act as 2 virtual switches.
I have two separate networks with their individual DHCP servers
- 10.0.10.0/24
- 10.0.20.0/24
I have configured 2 VLANs on N3048
- port 1-12 - VLAN 10
- port 13-24 - VLAN 20
when connecting only one of the networks everything works fine, but as soon as I connect the other, one of the VLANs stops communicating with the DHCP
config

Hi, Thank you for your post. Please note that the forum does not support initial deployment or configuration issues. If you need assistance with these tasks, you can contact to get a quote for our Deployment Services. However still i will try to help. As I can see, it seems correctly configured. to enable DHCP requests from one VLAN to reach the DHCP server on the other VLAN, you may need to configure the switch to relay them. This can be done by using the “ip helper-address” command on the VLAN interfaces and entering the IP address of the DHCP server on the other VLAN. (https://dell.to/3MDtIIj)
