FS/S3526C Ethernet switches support the super VLAN feature.
4.1 Overview of Super VLAN
To save IP address resources, the super VLAN concept (also known as VLAN
aggregation) was developed. Its principle is like this: a super VLAN may include
multiple sub VLANs (as subnets), with each as a broadcast domain. The super VLAN
can be assigned with an IP address, but not the sub VLAN. Layer 2 isolation is
implemented between sub VLANs. When users in different sub VLANs want Layer 3
communication, they use the IP address of the super VLAN as their gateway address.
IP address resources are saved since multiple VLANs share one IP address. ARP
proxy enables Layer 3 interworking between sub VLANs and their interworking with
other networks by forwarding and handling ARP request and response packets.
4.2 Super VLAN Configuration
Super VLAN configuration tasks are described in the following sections:
z Configuring a super VLAN
z Configuring a sub VLAN
z Configuring the mapping between super VLAN and sub VLAN
4.2.1 Configuring a Super VLAN
