3.4.5. Service VLAN

In certain scenarios, it is desirable to wrap traffic from multiple VLANs inside a single parent
VLAN. This is sometimes referred to as a Q-in-Q VLAN or a Stacked VLAN. In NetDefendOS, it is
called a Service VLAN and follows the standard defined by IEEE 802.1ad. It can be said that a
service LAN tunnels other VLANs and provides a convenient method of using a single logical
connection on a single Ethernet interface through which multiple VLANs can flow.
A Service VLAN Use Case
A NetDefend Firewall can act as a terminator for a service VLAN. A typical use case for service
VLAN termination is illustrated in the diagram below.
Ethernet=lan
IP=vlan10_ip
Network=all-nets
VLANID=10
