1.1.1.10, address range of VLAN4 from 1.1.1.20 to 1.1.1.30, layer-3 flows of terminals within
two address ranges allows to be forwarded only. To implement this requirement, it needs to
configure supervlan on switch.

22.7.4 Super VLAN Troubleshooting
 Supervlan and these functions (VRRP, dynamic VLAN, private VLAN, multicast VLAN,
etc.) are mutually exclusive, so they should not be used at the same time.
 arp-proxy of subvlan takes effect to only one subvlan. Flow received by VLAN with
arp-proxy can be forwarded to other VLAN. When two devices send flows to each other at
different subvlan, please enable arp-proxy function on two subvlans.
 Sub vlan can not set layer-3 interface.
 When creating/deleting supervlan, VLAN needs to ensure no layer-3 interface, if not, it will
result in error.
 If interface of supervlan specifies IP address range, but do not specify address range of
subvlan, address range set by interface is standard. If both interface and subvlan specify
IP address range, please check whether packets are within subvlan address range firstly,
second, check whether packets are within interface address range. After that, packets
