). A Cisco account is required.
The following known issues are reported in Version 6.0.1:
The system allows you to select a custom context on the ASA FirePOWER Configuration page (Configuration 
> ASA FirePOWER Configuration) of an ASA Firepower module managed by ASDM running Version 6.0.1 
even though custom context is not supported on devices managed by ASDM. Cisco strongly recommends 
using admin context on the ASA FirePOWER Configuration page. (CSCus71713, CSCuy18360)
In some cases, the system takes several minutes or longer to save and update the base layer of an intrusion 
policy. (CSCux00181)
The system may experience dropped packets if you edit the access control policy to an intrusion preventative 
default action and deploy to registered devices configured with routed, transparent, or inline interfaces. 
(CSCux02726)
In some cases, if a 7000 Series or 8000 Series high availability pair and the Firepower Management Center 
experiences a disruption in communication, you cannot break the high availability pair. If you cannot break a 
high availability pair, contact Support. (CSCux18768)
