Configuring the LNS for RADIUS Tunnel Accounting
To configure the LNS for RADIUS tunnel accounting, perform the following required configuration
tasks:
• Configuring AAA Accounting Using Named Method Lists, page 5-39
• Configuring RADIUS for Tunnel Accounting, page 5-39
Configuring AAA Accounting Using Named Method Lists
To configure AAA accounting using named method lists, enter the following commands beginning in
global configuration mode:
Note System accounting does not use named method lists. For system accounting you can define only the
default method list. For more information, see the “Configuring Accounting” chapter in the Cisco IOS
Security Configuration Guide, Release 12.2.
Configuring RADIUS for Tunnel Accounting
Cisco IOS Release 12.2(15)BX enhances the AAA accounting feature by adding the ability to include
tunnel-related statistics in the RADIUS information. To collect tunnel usage information, you must
configure the following attributes on the RADIUS server:
• Acct-Tunnel-Connection—Specifies the identifier assigned to the tunnel session. This attribute and
the Tunnel-Client-Endpoint and Tunnel-Server-Endpoint attributes provide a way to uniquely
identify a tunnel session for auditing purposes.
• Acct-Tunnel-Packets-Lost—Specifies the number of packets lost on a given link.
