Use L2TP v3 to create tunnels for transporting layer 2 frames. L2TP v3 enables WiNG supported controllers to create tunnels for transporting Ethernet frames to and from bridge VLANs and physical ports. L2TP v3 tunnels can be defined between WiNG managed devices and other vendor devices supporting the L2TP v3 protocol.
To define an L2TPv3 tunnel configuration:
icon to add a new policy.
| Setting | Description |
|---|---|
| Cookie Size | Displays the size of each policy's cookie field within each L2TP V3 data packet. L2TP V3 data packets contain a session cookie which identifies the session (pseudowire) corresponding to it. If using the CLI, the cookie size can't be configured per session, and are the same size for all sessions with in a tunnel. Use the drop-down list box to select a cookie size. The options include 0B, 4B, and 8B |
| Hello Interval | Displays each policy‘s interval between L2TPv3 hello messages exchanged within the L2TPv3 connection. Set the time limit between 1 to 3,600 seconds. The default option is 60 seconds |
| Reconnect Attempts | Lists each policy‘s maximum number of re-connection attempts to reestablish a tunnel between peers. The range is between 0 and 8 |
| Reconnect Interval | Displays the duration set for each listed policy between two successive reconnection attempts. The range is 1 to 3,600 seconds. The default option is 120 seconds |
| Retry Attempts | Lists the number of retransmission attempts set for each listed policy before a target tunnel peer is defined as not reachable. The range is 0 through 10, and the default is 5 |
| Retry Interval | Lists the interval the interval (in seconds) set for each listed policy before the retransmission of a L2TPv3 signaling message. The range is 1 through 350 seconds, and the default is 5 seconds |
| RX Window Size | Displays the number of packets that can be received without sending an acknowledgment. The range 0 through 15, and the default is 10 |
| TX Window Size | Displays the number of packets that can be transmitted without receiving an acknowledgment. The range is 0 through 15, and the default is 10 |
| Failover Delay | Lists the time in seconds for establishing a tunnel after a failover (VRRP, RF Domain, or Cluster). The range is 5 to 60 seconds, and the default is 5 seconds |
| L2 Path Recovery | Lists whether force L2 path recovery is activated or deactivated. Once a tunnel is established, enabling this setting forces server and gateway learning behind the L2TPv3 tunnel |
