Appendix C Action Handlers - Cisco ASR 9000 Series Configuration Manual

Action Handlers
An action handler performs specific tasks in response to certain events. The following action handlers are
currently supported in BNG.
• Authorization Action Handler, on page 307
• Authentication Action Handler, on page 307
• Disconnect Action Handler, on page 308
• Activate Action Handler, on page 308
• Deactivate Action Handler, on page 308
• Set Timer and Stop Timer Action Handlers, on page 308
Authorization Action Handler
The authorization action handler obtains authorization data for a specific subscriber identity from external
AAA servers. The authorization action handler is an asynchronous function. It collects identity information
from Subscriber Attribute Database (SADB) as well as the user credential data based on the identifier type
specified in the CLI. This information along with method list name is sent to the AAA authorization
coordinator. Once the AAA processing is done, the control is returned to the Policy Rule Engine (PRE)
action handler to complete the event processing. The configuration example is as follows:
1 authorize aaa list <list-name> [identifier <identifier-type> | format <format_name>
password ['use-from-line'| <user-cfg-password>
Password is a mandatory, regardless of whether the user selects use-from-line or provides a specific value
Note
to use for authorization.
Authentication Action Handler
The authentication action handler gathers information like protocol type, service type, authentication type,
user name, chap attributes, and user password and passes them to the AAA coordinator along with the AAA
method list name. The authentication action handler is an asynchronous function. Once the AAA processing
is done, the control is returned to the PRE action handler to complete the event processing. The configuration
example is as follows:
1 authenticate aaa list <list-name>
