Figure 11 Per-VLAN Relay
If the relay is configured with the correct remote DHCP server address, go to step 6.
If the relay is not configured with the correct remote DHCP server address,
re-configure and repeat step 3.
Is the switch’s VLAN interface for client using the correct IP
subnet?
The DHCP server will provide its dynamic configuration based on the DHCP relay’s
VLAN interface towards the DHCP client. This means that if a client sends a DHCP
discover to the DHCP relay on VLAN 10, the DHCP relay sends this request to the
DHCP server using its VLAN 10 IP address. The DHCP server then matches the VLAN
10 IP address into its local pool to determine which dynamic configuration for clients
to use.
