If you use a RADIUS server to authenticate the L2TP tunnel parameters, you must
configure the format for both the L2TP Calling Number AVP 22 (by using the aaa
tunnel calling-number-format command) and the RADIUS Calling-Station-ID [31]
attribute (by using the radius calling-station-format command).
However, if you use an AAA domain map to authenticate the L2TP tunnel parameters,
you need configure only the L2TP Calling Number AVP 22 format by using the aaa
tunnel calling-number-format command. You need not configure the format of the
RADIUS Calling-Station-ID [31] attribute in this case.

Configuring the Fallback Format

You can configure a fallback AVP 22 format. The E Series LAC uses the fallback format
to generate the L2TP Calling Number AVP 22 in the event that the PPPoE agent ID
is null or unavailable. The LAC uses the fallback format only when the configured
calling number format includes either or both of the agent-circuit-id and
agent-remote-id suboptions.
The calling number format determines what element triggers use of the fallback
format, as shown in the following table:
You use the aaa tunnel calling-number-format-fallback command to configure the
router to generate any of the following fallback AVP 22 formats:
354
Configuring the Fallback Format
Set the format of the RADIUS Calling-Station-Id to fixed-format, and specify the
optional stacked keyword to include the S-VLAN ID.

elements:

fixed This format is similar to the fixed format of RADIUS attribute 31
