Does IOS XE not support debugging of received packets with the "debug ip packet" output? I have a case where the router only shows locally generated packets in "debug ip packet [detail]" output, but nothing that is being received. This is both for data plane, e.g. ICMP echo, and for control plane, e.g. EIGRP or OSPF hellos. I tried disabling CEF as well but it's not supported on this platform:
Router(config)#no ip cef distributed
%Cannot disable CEF on this platform
Router(config-if)#no ip route-cache
Platform cannot disable ip route-cache on GigabitEthernet1 interface
This is on IOS XE ver 03.11.00.S for CSR1000v.
