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. Mobility 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.
To define or override an L2TPV3 configuration for an access point profile:
Switch VLAN Interface Use the spinner control to select a VLAN (1 - 4094) for an address requiring resolution.
IP Address Define the IP address used to fetch a MAC address.
MAC Address Displays the target MAC address that’s subject to resolution. This is the MAC used for mapping an
IP address to a MAC address that’s recognized on the network.
Device Type Specify the device type the ARP entry supports (either Host, Router or DHCP Server). Host is the
default setting.
