Enhanced Subscriber Management (ESM), Distributed Subscriber Management (DSM), and IPsec accounting generate Accounting Interim Update messages periodically or triggered by an event. The reason for the Accounting Interim Update message is included in the [26.6527.163] Alc-Acct-Triggered-Reason attribute.
For ESM, sending of Accounting Interim Updates and inclusion of the [26.6527.163] Alc-Acct-Triggered-Reason attribute must be enabled explicitly using following configuration:
subscriber-mgmt
radius-accounting-policy "acct-policy-1" create
host-accounting interim-update # maximum two accounting
queue-instance-accounting interim-update # modes can be enabled
session-accounting interim-update # simultaneously
include-radius-attribute
alc-acct-triggered-reason
exit
exit
Table: Accounting triggered reason specifies the different Accounting Triggered Reason values generated by the SR OS in [26.6527.163] Alc-Acct-Triggered-Reason attribute.
