Figure 2-2 Specify DHCP Server for VLAN
Follow these steps to specify DHCP Server for the specific VLAN:
1) In the Default Relay Agent Interface section, configure the management VLAN (by
default, it is VLAN 1) as the default relay agent interface. The switch will use its IP
address to fill in the relay agent IP address field in DHCP packets when applying for IP
addresses from the DHCP server. Click Apply.
Interface ID Specify the type and ID of the interface that needs to be configured as the default
relay agent interface.
You can configure any existing layer 3 interface as the default relay agent
interface. The DHCP server will assign IP addresses in the same subnet with this
relay agent interface to the clients who use this relay agent interface to apply for
IP addresses.
IP Address Displays the IP address of this interface.
