Planning Cisco ASA Migration

I'm planning to migrate an ASA firewall to a ASA NGFW-X.

I know there are a Cisco migration path recommendations, but I would like to test the current firewall with some commands to know this firewall is not at its performance limit and to make the decision based in some data or study

what commands can I use to test the current firewall performance?

Hi,Checking performance on

Hi,

Checking performance on the ASA device can be tricky. You would see the normal indicators as the latency , throughout speeds etc.

These are some of the commands that would give an indication about the ASA heath:-

1) show int details :- Check for interface errors

2) show cpu :- Check for High CPU

3) show mem :- Check for High Memory

4) show blocks:- For any block depletion.

These are some of the Basic indicators.

Let me know if you have any other queries.

Thanks and Regards,
