Hi

When u configure ip helper-address (dhcp server ip) under the specific SVI its going to act as relay agent..do mean this or u want the router or the switch to be act as a dhcp server.

Thanks

please note that when setting the dhcp relay, dhcp request are tagged with the SVI ip network/subnet, so you have to set an according configuration (i.e. dhcp scope) on the server.

e.g. if svi receiving and forwarding the dhcp request has ip address 192.168.1.1/24, you must set a dhcp scope for network 192.168.1.0/24 on the server.

The term Relay Agent usually implies IPv6.

Before we jump into IPv6 details, could you confirm IPv4 or IPv6.
