Cisco Firepower FMC Quarterly Cleanups. Do this!
When I’m working at a customer I try and setup as much task management by going to System>Tools>Scheduling, and using all the Add Task programs I can.
I have to assume that about a week after I leave they will stop logging in and providing the advanced network analysis that I taught them (just like when we signup for the gym each January), and which is critical to the support of Cisco Firepower.
However, there is something else that is critical to the support and health of your Cisco Firepower Management Center (FMC), and that is data purging the system, which I tell people to do quarterly, but yearly could probably work too (depends on how much data you have).
I am not talking about the purge function found at System>Tools>Data Purge
This would purge data you actually need and and this data rolls over anyway based on your settings in System>Configuration>Database
So I have something else that will be useful to show you in this post.
Here is your list of useful cleanups for your FMC
All of these are non-invasive, meaning you don’t need to create a maintenance window for this process
If you schedule reports, which you should be doing, then this will area will fill up rather quickly. For my customers, I schedule 15-20 reports a week, so in a quarter that could be around 200 reports, or in a year close to 800 old reports stored in here. Since these should being sent and stored in your remote storage area (System>Configuration>Remote Storage Device), these can and should be purged.
2. System>Updates>Product Updates
This area may be the most important as this gets updates quickly, assuming you have download updates automatically in your task management, which you should. Even if you decide to provide this function manually, it is important to purge this page, as this can get confusing real fast with all the various type of updates showing up weekly. Cleaning these out quarterly will help you maintain your updates and your sanity.
You should be backing up your FMC nightly, and also moving the backups to your remote storage device area since the backups are only stored on your FMC by default. These backups can be 250-300MB or much more more. At 365 backups a year, that’s a lot of storage needed for old backups which you no longer need, so make sure and clean this area out.
