Limitation: large ASA running configuration files

Configuration file size limitations

Be aware that Security Cloud Control cannot predictably manage ASA devices with running configuration files that are 4.5 MB or larger, contain approximately 22,000 lines or more, or have too many access-list entries for a single access group.

This limitation affects ASA onboarding and ongoing management in Security Cloud Control. You may see behavior such as the ASA failing to onboard, Security Cloud Control not displaying all of the configuration defined in the ASA's running configuration file, or Security Cloud Control failing to write to the change log.

When you onboard an ASA to Security Cloud Control, Security Cloud Control stores a copy of the ASA's running configuration file in its database. Large configuration files exceed database storage and processing capabilities.

To confirm the size of your running configuration file, see Confirming ASA running configuration size. Contact your Cisco account team for help safely reducing the size of your configuration file without disrupting your security policies.
