| What to record | Where to read it | What it rules out |
|---|---|---|
| Negotiated transform and SA identifiers | show crypto ipsec sa for that peer and direction | "the configuration picked the wrong algorithm" |
| Offload or accelerator state for that build | platform show commands and interface statistics | "the crypto engine is the ceiling" |
| Payload size and offered rate | the test tool's own settings and summary | "packets per second versus bytes per second" |
| Delivered rate and loss at the receiver | the receiving endpoint, not the sender's counters | "the sender transmitted, so it arrived" |
| Access-link load and drops | underlay interface counters along the path | "the bottleneck lives inside the tunnel" |
