4510G DHCP Helper/Relay

[Nick1504]

Hi Guys, I am having a problem setting up 2 additional dhcp relays.

Current setup: Existing VLAN 100 working DHCP, require VLAN 2 and VLAN 200 also on DHCP.

All will be using the same server.

Hi Nick.

Since you already use the DHCP server in the VLAN 100 and will use it for the other two new VLANs, I assume that it uses a single IP address.

Once the server are located in a different VLAN than the new ones, you have to use DHCP Relay.

You just need to create a DHCP Server group (maybe you already have this group created):

dhcp relay server-group <group-id> ip <server_ip-address>
interface vlan <vlan_id>
dhcp relay server-select <group-id>

You can use up to eight IP addresses at the group.

Regards.
