5.4.5.4.3 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 controllers and access points to create tunnels
for transporting Ethernet frames to and from bridge VLANs and physical ports.
Multiple pseudowires can be created within an L2TP V3 tunnel. WING supported access points support an Ethernet VLAN
pseudowire type exclusively.
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.
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.
NOTE: If connecting an Ethernet port to another Ethernet port, the pseudowire type
must be Ethernet port, if connecting an Ethernet VLAN to another Ethernet VLAN, the
pseudowire type must be Ethernet VLAN.
