SubVLAN Address Range Checking
  
  
    
      You can configure subVLAN address ranges on each subVLAN to prohibit the entry of IP
        addresses from hosts outside of the configured range.
     
    - 
        To configure a subVLAN range, use the following
          command:
        configure vlan vlan_name
          subvlan-address-range ip address1 - ip
          address2 
- 
        To remove a subVLAN address range, use the following
          command:
        unconfigure vlan vlan_name
          subvlan-address-range 
- 
        To view the subVLAN address range, use the following
          command:
        show vlan {virtual-router
          vr-name}
