Connect to the switch via telnet and enter the first command to switch to configuration mode:

system-view

Add any required number of VLANs, for example:

vlan 226
quit
vlan 227
quit
vlan 228
quit
...

Add a super vlan:

vlan 10
name supervlan
supervlan
subvlan 226 227 228
quit

Add a super VLAN interface, configure DHCP relay so that users receive IP and enable local-proxy-arp:

interface Vlan-interface10
ip address 172.16.0.1 255.255.192.0
dhcp select relay
dhcp relay server-select 0
local-proxy-arp enable
quit

You can view the current and saved configuration with the commands:

display current-configuration
display saved-configuration

If everything worked, then you can save the configuration with the command:

save main

All subvlans that are included in the supervlan should be without interfaces. You can delete the VLAN interface, for example, with the following commands:

interface Vlan-interface227
undo ip address 172.16.64.1 255.255.192.0
quit
undo interface Vlan-interface227

This completes the super VLAN setting.
