Operation Manual – Extended VLAN ApplicationH3C S7500 Series Ethernet Switches Chapter 3 Super VLAN3-63.4.2 Super VLAN Supporting DHCP Relay ExampleI. Network requirementsz Create VLAN 6 and configure it as a super VLAN, and create VLAN 2 and VLAN 3as the sub VLANs which map with VLAN 6.z Configure the IP address of the VLAN 6 as 10.1.1.1, and the sub network mask as255.255.255.0.z Enable the DHCP relay function on the VLAN interface of VLAN 6, and establishthe mapping between VLAN 6 and the remote DHCP server group 2 to make thehosts in VLAN 2 and VLAN 3 be able to dynamically obtain IP addresses from theDHCP server group 2.II.
