Adding and Editing Manual Sessions

You can add a new L2TPv3 manual session configuration or edit an existing configuration.

  1. Select Add to create a new manual session, Edit to modify an existing session configuration or Delete to remove a selected manual session.

  2. Set the following manual session Settings parameters:

    Name

    If creating a new manual session, define a 31 character maximum name for this tunnel session. The session is created after a successful tunnel connection and establishment. Each session name represents a single data stream.

    IP Address

    Specify the IP address used as the tunnel source IP address. If not specified, the tunnel source IP address is selected automatically based on the tunnel peer IP address. This address is applicable only for initiating the tunnel. When responding to incoming tunnel create requests, it would use the IP address received in the tunnel creation request.

    IP

    Set the IP address of an L2TP tunnel peer. This is the peer allowed to establish the tunnel.

    Local Session ID

    Set the numeric identifier for the tunnel session. This is the pseudowire ID for the session. This pseudowire ID is sent in session establishment message to the L2TP peer.

    MTU

    Define the session MTU as the size (in bytes) of the largest protocol data unit the layer can pass between tunnel peers in this session. A larger MTU means processing fewer packets for the same amount of data.

    Remote Session ID

    Use the spinner control to set the remote session ID passed in the establishment of the tunnel session. Assign an ID in the range of 1 - 4,294,967,295.

    Encapsulation

    Select either IP or UDP as the peer encapsulation protocol. The default setting is IP. UDP uses a simple transmission model without implicit handshakes.

    UDP Port

    If UDP encapsulation is selected, use the spinner control to define the UDP encapsulation port. This is the port where the L2TP service is running.

    Source VLAN

    Define the VLAN range (1 - 4,094) to include in the tunnel. Tunnel session data includes VLAN tagged frames.

    Native VLAN

    Select this option to define the native VLAN that will not be tagged.

  3. Select the + Add Row button in the Cookie table to set the following:

    Cookie Size

    Set the size of the cookie field within each L2TP data packet. Options include 0, 4 and 8. The default setting is 0.

    Value 1

    Set the cookie value's first word.

    Value 2

    Set the cookie value's second word.

    End Point

    Define whether the tunnel end point is local or remote.

  4. Select OK to save the changes to the session configuration. Select Reset to revert to the last saved configuration.
