WAN-side VLAN Tagging

Introduction
In order to support WAN-side VLAN tagging, logical Ethernet interfaces are stacked on top of each other.
Several logical Ethernet interfaces with different VLANs (tagged) are created on top of a single logical
Ethernet interface with the default VLAN (untagged).
Configuring WAN-side VLAN tagging
To configure WAN-side VLAN tagging, execute following steps:
1 Create the necessary VLANs:
=>:eth vlan add name=video vid=2
=>:eth vlan add name=voice vid=3
2 Create a first logical Ethernet interface:
=>:eth ifadd intf=eth_total
=>:eth ifconfig intf=eth_total dest=atm_total wan=enabled
=>:eth ifattach intf=eth_total
3 On top of this interface, configure several logical Ethernet interfaces that support VLAN tagging:
=>:eth ifadd intf=eth_video
=>:eth ifconfig intf=eth_video dest=eth_total wan=enabled vlan=video
=>:eth ifattach intf=eth_video
=>:eth ifadd intf=eth_voice
=>:eth ifconfig intf=eth_voice dest=eth_total wan=enabled vlan=voice
=>:eth ifattach intf=eth_voice
