When connectivity issues are detected between Cisco Secure Firewall Management Center (FMC) and Cisco Secure Firewall Threat Defense (FTD) devices, and initial troubleshooting indicates that heartbeats and events are not being received, the engineer can run the following commands to resolve the issue by re-establishing secure channels and checking process statuses:
* manage_procs.pl: This script is used to manage and restart processes on the FTD device. Running this script can help restart any malfunctioning processes and re-establish connectivity between the FMC and FTD.
* sudo stats_unified.pl: This command provides detailed statistics and status of the unified system processes. It helps in diagnosing and resolving issues related to the secure channel and event reporting.
Steps:
* Access the FTD CLI.
* Run the command manage_procs.pl to restart processes.
* Run the command sudo stats_unified.pl to gather detailed process statistics and verify the status.
These commands help resolve connectivity issues by ensuring that all necessary processes are running correctly and secure channels are re-established.
