You can configure the router to use QoS settings to calculate the transmit connect speed
of the subscriber's access interface reported for an L2TP tunneled session. The router
reports the transmit connect speed in L2TP Transmit (TX) Speed AVP 24. During the
establishment of an L2TP tunneled session, the LAC sends AVP 24 to the LNS to convey
the transmit speed of the subscriber's access interface.
You can configure QoS to control the rate for any of the logical interfaces of the following
interface columns:
ATM 1483 subinterface over ATM VP over ATM interface
PPPoE subinterface over Ethernet interface
PPPoE subinterface over VLAN subinterface over Ethernet interface
For those logical interfaces with a rate controlled by QoS, QoS reports this configured
rate as the transmit connect speed for that interface. For the logical interfaces that do
not have a QoS-configured rate, QoS reports the speed of the underlying physical port
as the transmit connect speed.
For each logical interface, QoS determines the rate of the interface using either the
shaping rate or the shared-shaping rate, if one is configured. The numeric value of the
