Calling Number AVP 22 Configuration Tasks

Configuring the Fallback Format

Copyright © 2010, Juniper Networks, Inc.
Example—The following command configures the L2TP Calling Number AVP in
fixed-adapter-new-field format for an Ethernet interface with an S-VLAN ID:
host1(config)#aaa tunnel calling-number-format fixed-adapter-new-field stacked
For example, when you configure this Calling-Station-Id format on an E320 router
for an Ethernet interface on system name western, slot 4, adapter 1, port 3, S-VLAN
ID 8, and VLAN ID 12, the virtual router displays the format in ASCII as 'west' '04' '1'
'03' '0008' '0012'.
Tasks for configuring the L2TP Calling Number AVP 22 include:
Calling Number AVP 22 Configuration Tasks on page 353
Configuring the Fallback Format on page 353
Disabling the Calling Number AVP on page 357
To set up the router to generate Calling Number AVP 22 for an Ethernet interface in fixed
format that includes both an S-VLAN ID and a VLAN ID:
Set the calling number format of the tunnel to fixed, and specify the optional stacked
1.
keyword to include the S-VLAN ID.
host1(config)#aaa tunnel calling-number-format fixed stacked
Set the format of the RADIUS Calling-Station-Id to fixed-format, and specify the
2.
optional stacked keyword to include the S-VLAN ID.
host1(config)#radius calling-station-format fixed-format stacked
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.
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:
