Handling of SPV and restart services

In case icwmpd receives SetParameterValues Request from the ACS, it will use the set ubus method of bbfdmd daemon(bbf ubus object), for all requested parameters.

Based on the response of set the icwmp will do the following:

  • in case of fault icwmp aborts the set of all parameters and then sends Response to the ACS with FAULT 9003 including all parameters faults as defined in TR069 standard.
  • in case of success icwmp commits the set of all parameters, without applying them so without restarting services, and then sends a success Response to the ACS including the status code 1.
  • All required services(whose configuration has been modified by SPV) are restarted at the end of CWMP session in order to prevent any session interruption.

!!! note

icwmp always returns 1 as status value in case of success of SPV because all services are restarted at the end of the session.
