Sync and analysis behavior
Policy Analyzer and Optimizer displays policy metadata, including analysis status, last modified time, and last analyzed time. Last modified reflects changes made to the policy in the management center that manages it. Last analyzed reflects the analysis run that produced the current Policy Analyzer and Optimizer summary.
Use Sync with FMC to fetch the latest access control and NAT policy inventories and modified timestamps from the management center. Each Policy Analyzer and Optimizer tab shows the sync success or failure status for the policy type on that tab. If a policy was modified after the last analysis, the displayed analysis can be out of date until you run analysis again or a scheduled analysis runs.
