CA ITCM 14.0 or higher

Starting ITCM 14.0 caf is checking if the machine has an ipaddress allocated by APIPA (Automatic Private Internet Protocol Addressing). APIPA allocates IP addresses in the private range to

At startup of caf, if an APIPA address is found, caf does 3 checking with a delay of 60 seconds between checking. This is used to let time for DHCP server to allocate an address.


The 3 checking and the delay of 60 seconds could be configured in comstore.


ITCM 14.0

In ITCM 14.0, following command could be executed on the machines :

Example for 2 retries with a delay of 15 seconds between retries :


ccnfcmda -cmd SetParameterValue -ps trm/common/caf/general -pn apipa_retry -v 2

ccnfcmda -cmd SetParameterValue -ps trm/common/caf/general -pn apipa_delay -v 15

ITCM 14.0 SP1 or higher

These 2 parameters are managed by a configuration policy under :

DSM/Common Components/CAF/General/CAF: APIPA Delay (default value is 60) 

DSM/Common Components/CAF/General/CAF: APIPA Retry (default value is 3) 



Create or Update a configuration applied on the machines and change the values for these 2 parameters to the desired values.
