Known Affected Releases

9.12(4.2) 9.6(4.8)

Description (partial)

This is an enhancement request. ASA should not disable failover and put "no failover" into the configuration in case of failover progression failure as this can sometimes lead to a situation when both units become active, i.e. both units may start using same IP addresses. The idea of this enhancement request is to change the current failover behaviour when the unit hit the critical condition

Today's state:
 DISABLED	-	If 'no failover' is configured by the user or 'no failover'  added automatically in case of progression failure

 DISABLED	-	If 'no failover' is configured by the user.
 SHUN / MUTE	-	Unit hit the critical condition and stops negotiating with the peer. Running config will still have 'failover'.

This implementation flaw exists in all ASA releases
