SG300 DHCP Relay

Eric Wilkins
Level 1
Level 1

Hello,

I have configured a DHCP server with IP's for 3 VLANs:

192.168.20.1

192.168.30.1

192.168.40.1

On my SG300 I have configured Option 82, DHCP Relay and the IP addresses of my DHCP server which my subnets are on 3 different NICS on the server each with an excluded IP with in each subnet which would be IP ending in .252 for each subnet.

So the DHCP Relay Server IPs are the following:

192.168.20.252

192.168.30.252

192.168.40.252

I have configured the DHCP Interface Tables as the following using VLAN numbers:

VLAN 20 192.168.20.1

VLAN 30 192.168.30.1

VLAN 40 192.168.40.1

I cannot get any DHCP assigned IP on any device connected directly to a switch port setup as an access port for one of the VLANS.

I pretty sure it's something on the switch but just need help figuring that out if someone already has experience get this working.

Thanks!
