If there is no explicit static configuration for the layer 2 interface, L2TP reports the
speed of the underlying physical port as the transmit connect speed.
Dynamic Layer 2
The dynamic layer 2 method calculates the transmit connect speed of the subscriber’s
access interface based on the dynamically configured settings for the underlying
layer 2 interface.
If there is no dynamic configuration for the layer 2 interface, L2TP reports the transmit
connect speed based on statically configured settings. If there is no static speed
configuration for the layer 2 interface, L2TP reports the speed of the underlying
physical port as the transmit connect speed.
QoS
The QoS method calculates the transmit connect speed of the subscriber’s access
interface based on settings determined by static or dynamic QoS configurations. This
calculation is based on the interface columns that QoS uses to build scheduler profiles
for L2TP sessions. For example, a typical interface column might consist of an L2TP
session over an Ethernet VLAN over a Gigabit Ethernet interface.
You can configure QoS to control the rate of any logical interface in the interface
column. For those logical interfaces with a rate controlled by QoS, QoS reports this
configured rate as the transmit connect speed for that interface. For those logical
interfaces that do not have a QoS-configured rate, QoS reports the speed of the
underlying physical port as the transmit connect speed.

Actual
The actual method calculates the transmit connect speed of the subscriber’s access
interface as the lesser of the following two values:
■
Value using the dynamic layer 2 calculation method
■
Value using the QoS calculation method
Transmit Connect Speed Calculation Examples
The examples in this section illustrate how the router uses the methods described
in “Transmit Connect Speed Calculation Methods” on page 401 to calculate the transmit
connect speed.
Example 1: L2TP Session over ATM 1483 Interface
In this example, an L2TP session is established over an ATM 1483 subinterface on
an OC3/STM1 ATM IOA. The configuration has the following characteristics:
■
There is no explicit static configuration for the layer 2 (ATM 1483) interface.
