Impact of OGS on Cisco Secure Firewall Threat Defense
Michelle Epar from Cisco explains the impact of using optimization commands (OGS) in network devices, highlighting its benefits in reducing memory usage and deployment time but noting potential increases in CPU usage.
MAIN POINTS FROM TRANSCRIPT
- OGS reduces memory elements by optimizing access rule matches using object groups.
- Enabling OGS may increase CPU usage due to decreased rule lookup performance.
- Example shows significant reduction in elements with OGS enabled, from 81 to 1.
- Enabling OGS requires recompiling rules, best done during a maintenance window.
TAKEAWAYS
- OGS can significantly improve deployment time by reducing memory usage.
- CPU usage may increase, requiring careful consideration of device capabilities.
- The configuration process for OGS is straightforward, with a simple checkbox activation.
- Each network topology is unique, necessitating a balanced approach to OGS implementation.
