VLAN AND DHCP

Hi,

We are being tested for a VLAN with DHCP (one vlan with one DHCP).

We took a Dell 6248 switch, put 2 ports in general mode with VLAN 500 tagged (for our SSID) and the native VLAN (1) untagged.

Our SSID only allows access to the Internet.

On the AP1, we set DHCP. When the notebook is connected above, we retrieve an IP well and we have access to the Internet.

On the AP2, we set DHCP relay. When the notebook is connected above, we retrieve an IP well but we did not have Internet access.

For example: we are connected to the AP1 (IP + Internet), it disconnects to move to the AP2, we lose the Internet but no the IP.

If all devices are on vlan 1, no need for DHCP relay, they're in the same broadcast domain.

I apologize, vlan 500. Either way, all traffic is on a single vlan, single broadcast domain. Just make sure the switch ports are configured for these vlans. You can also perform a vlan probe from each of the APs to ensure connectivity to the DHCP server.

Hi BJ,

Thanks for the answer but i don't understand why I lost Internet when I connect on the AP2.
