5.10.2.3 Overriding a L2TPv3 Profile Configuration

Overriding the Network Configuration
L2TP V3 is an IETF standard used for transporting different types of layer 2 frames in an IP network (and access point
profile). L2TP V3 defines control and encapsulation protocols for tunneling layer 2 frames between two IP nodes.
Use L2TP V3 to create tunnels for transporting layer 2 frames. L2TP V3 enables WING supported controllers and access
points to create tunnels for transporting Ethernet frames to and from bridge VLANs and physical ports. L2TP V3 tunnels
can be defined between WING devices and other vendor devices supporting the L2TP V3 protocol.
Multiple pseudowires can be created within an L2TP V3 tunnel. WING supported access points support an Ethernet VLAN
pseudowire type exclusively.
Ethernet VLAN pseudowires transport Ethernet frames to and from a specified VLAN. One or more L2TP V3 tunnels can be
defined between tunnel end points. Each tunnel can have one or more L2TP V3 sessions. Each tunnel session corresponds
to one pseudowire. An L2TP V3 control connection (a L2TP V3 tunnel) needs to be established between the tunneling
entities before creating a session.
For optimal pseudowire operation, both the L2TP V3 session originator and responder need to know the psuedowire type
and identifier. These two parameters are communicated during L2TP V3 session establishment. An L2TP V3 session
created within an L2TP V3 connection also specifies multiplexing parameters for identifying a pseudowire type and ID.
The working status of a pseudowire is reflected by the state of the L2TP V3 session. If a L2TP V3 session is down, the
pseudowire associated with it must be shut down. The L2TP V3 control connection keep-alive mechanism can serve as a
monitoring mechanism for the pseudowires associated with a control connection.
To define or override an L2TPV3 configuration for an access point profile:
1. Select Devices
2. Select a target device from the Device Browser in the lower, left-hand, side of the UI
3. Select Profile Overrides
4. Select Network
5. Select L2TP V3.
NOTE: A pseudowire is an emulation of a layer 2 point-to-point connection over a
packet-switching network (PSN). A pseudowire was developed out of the necessity to
encapsulate and tunnel layer 2 protocols across a layer 3 network.

NOTE: A blue override icon (to the left of a parameter) defines the parameter as having
an override applied. To remove an override, go to the Basic Configuration screen's Device
Overrides field and select Clear Overrides. This will remove all overrides from the device.
