Access points use L2TP V3 to create tunnels for transporting layer 2 frames. L2TP V3 enables an
access point to create tunnels for transporting Ethernet frames to and from bridge VLANs and
physical ports. L2TP V3 tunnels can be defined between Mobility devices and other devices
supporting the L2TP V3 protocol.
To review a selected access point’s L2TPv3 statistics:
1. Select the Statistics menu from the Web UI.
2. Select System from the navigation pane (on the left-hand side of the screen). Expand a RF
Domain and select one of its connected access points.
3. Select L2TPv3.
FIGURE 58 Access Point - L2TPv3 screen
The Access Point L2TPv3 Tunnels screen displays the following:
Tunnel Name Displays the name of each listed L2TPv3 tunnel assigned upon creation. Each listed tunnel
name can be selected as a link to display session data specific to that tunnel. The Sessions
screen displays cookie size information as well as psuedowire information specific to the
selected tunnel. Data is also available to define whether the tunnel is a trunk session and
whether tagged VLANs are used. The number of transmitted, received and dropped packets
also display to provide a throughput assessment of the tunnel connection. Each listed session
name can also be selected as a link to display VLAN information specific to that session. The
VLAN Details screen lists those VLANs used an access point interface in L2TP tunnel
establishment.
Local Address Lists the IP address assigned as the local tunnel end point address, not the tunnel interface’s
IP address. This IP is used as the tunnel source IP address. If a local address is not specified,
the source IP address is chosen automatically based on the tunnel peer IP address.
Peer Address Lists the IP address of the L2TP tunnel peer establishing the tunnel connection.
Tunnel State States whether the tunnel is idle (not utilized by peers) or is currently active.
Peer Host Name Lists the assigned peer hostname used as matching criteria in the tunnel establishment
process.
Peer Control
Connection ID Displays the numeric identifier for the tunnel session. This is the peer pseudowire ID for the
session. This source and destination IDs are exchanged in session establishment messages
with the L2TP peer.
