Cisco FPR4120 running ASA with "No buffer" discards on the internal-data interfaces

MohammadKayed — Sun, 25 Apr 2021 16:04:14 GMT

Hello ,

I have FPR4120 running ASA , I can see no buffer counter is increasing on Internal-Data interface 0/0 and 0/1

What does it mean and how I can troubleshoot it ?

My CPU usage is 2% , and I don't notice any impact.

Can you post the interface output also what version of the ASA Code? what is the bandwidth the FW handling? (In most case we see no buffers increased due to ASA is being oversubscribed)

show interface gi x/x where you see no buffer increasing

here is Troubleshoot guide :
