Hi,

I have an issue like  large files  download drops or take much longer time than expected .

How do i verify asa drops  or its not an ASA issue.

It may the ISP limiting the bandwidth

Hi,

You can try capturing traffic on ingress and egress interface and analyse captures on the egress interface (ISP facing interface). Check if there is any latency in the traffic that you receive on the egress (refer timestamp) you can also check if there are too many retransmissions in the stream.

As the analysis require only headers so you can avoid capturing the entire packet and restrict captures to headers only for specific traffic.

Captures on ASA can be CPU intensive so ensure that you have very specific captures.

Hope it helps.
