Interface
The VPN Concentrator interface:
Ethernet 1 (Private) = Ethernet 1 (Private) interface.
Ethernet 2 (Public) = Ethernet 2 (Public) interface.
Ethernet 3 (External) = Ethernet 3 (External) interface.
WAN 1.A = WAN interface module in Slot 1, Port A
WAN 1.B = WAN interface module in Slot 1, Port B
WAN 2.A = WAN interface module in Slot 2, Port A
WAN 2.B = WAN interface module in Slot 2, Port B
1000 and up = VPN tunnels, which are treated as logical interfaces.
Status
The operational status of this interface:
UP = configured and enabled, ready to pass data traffic.
DOWN = configured but disabled.
Testing = in test mode; no regular data traffic can pass.
Dormant = configured and enabled but waiting for an external action, such as an incoming
connection.
Not Present = missing hardware components.
Lower Layer Down = not operational because a lower-layer interface is down.
Unknown = not configured.
