DGS-3627:admin# delete super_vlan vlanid 10
Command: delete super_vlan vlanid 10
Success.
DGS-3627:admin#
config sub vlan
Purpose This command is used to configure the IP range of the sub VLAN.
Syntax
config sub_vlan [<vlan_name 32> | vlanid <vlanid 1-4094>] [add | delete] ip_range
<ipaddr> to <ipaddr>
Description This command is used to configure the IP range of the sub VLAN.
A sub VLAN can has one or more IP ranges. Configuring IP range of sub VLAN can reduce
the ARP traffic in the super VLAN.
Sub VLAN mapping to IP range is 1 to n. That is multiple IP (ranges) is allowed to map to one
sub VLANs.
One IP can not map to multiple sub VLANs, if one IP map to multiple VLAN it may cause
traffic forwarding to wrong VLAN.
For example, if the IP range of a sub VLAN is 10.1.1.1-10.1.1.3, once the L3 switch received
an ARP request whose target IP is 10.1.1.2 from the sub VLAN, the switch know the target IP
in the sub VLAN and it does not send proxy ARP request to other sub VLANs.
Parameters
<vlan_name 32> - Specify the sub VLAN name. The VLAN name must be an existent VLAN
name.
vlanid <vlanid 1-4094> - Specify the sub VLAN ID
add ip_range <ipaddr> - Specify the IP range of the sub VLAN.
delete ip_range <ipaddr> - Specify the IP range no longer belong to the sub VLAN
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To configure IP range of sub VLAN 1 to 10.1.1.1-10.1.1.3:
DGS-3627:admin# config sub_vlan vlanid 1 add ip_range 10.1.1.1 to 10.1.1.3
Command: config sub_vlan vlanid 1 add ip_range 10.1.1.1 to 10.1.1.3
Success.
DGS-3627:admin#
show super vlan
Purpose This command is used to show super VLAN.

Super VLAN ID
Super VLAN name
IP subnet of the super VLAN associated interface.
Status: if any sub VLAN of the super VLAN has linkup member port, the super VLAN is
active. Otherwise, the super VLAN is inactive.
Sub VLAN set of the super VLAN.
Parameters
