Symptom

Router C8500 running IOS-XE 17.9.4 crashed due to software memory corruption when running the command "show platform software cef ipv4 feature-all".

Conditions

This issue is locally irreproducible and the root cause is unknown. So we treat it as a corner case and ignore it on all hardware variants and software releases. Issue happened 1> with Router C8500, IOS-XE 17.9.4, 2> when running manually show command "show platform software cef ipv4 feature-all" 3> root cause still unclear Issue is one time event and not reproducible. So for now, any HW variant and SW/IOS release are safe to Customers.

Workaround

No workaround.
