Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

To view the subVLAN address range, use the following command:

show vlan {detail {ipv4 | ipv6} | <vlan_name> {ipv4 | ipv6} | virtual-router 

<vr-router> | <vlan_name> stpd | security}

Isolation Option for Communication Between SubVLANs

To facilitate communication between subVLANs, by default, an entry is made in the IP ARP 
table of the superVLAN that performs a proxy ARP function. This allows clients on one 
subVLAN to communicate with clients on another subVLAN. In certain circumstances, 
intra-subVLAN communication may not be desired for isolation reasons. 

To prevent normal communication between subVLANs, disable the automatic addition of the 
IP ARP entries on the superVLAN using the following command:

disable subvlan-proxy-arp vlan [<vlan-name> | all]

 

The isolation option works for normal, dynamic, ARP-based client 

communication.

VLAN Aggregation Example

The follow example illustrates how to configure VLAN aggregation. The VLAN vsuper is 
created as a superVLAN, and subVLANs, vsub1, vsub2, and vsub3 are added to it.

Create and assign an IP address to a VLAN designated as the superVLAN. Be sure to 
enable IP forwarding and any desired routing protocol on the switch. 

create vlan vsuper



configure vsuper ipaddress 192.201.3.1/24



enable ipforwarding



enable ospf



configure ospf add vsuper area 0

Create and add ports to the subVLANs.

create vlan vsub1



configure vsub1 add port 10-12



create vlan vsub2



configure vsub2 add port 13-15



create vlan vsub3



configure vsub3 add port 16-18

Configure the superVLAN by adding the subVLANs.

configure vsuper add subvlan vsub1



configure vsuper add subvlan vsub2



configure vsuper add subvlan vsub3

Optionally, disable communication among subVLANs.

disable subvlan-proxy-arp vlan [<vlan-name> | all]
