What problem does it indicate when the input packets are ignored? I know that indicates the hardware runs low on internal buffers. Does it indicate a hardware issue? How do I check sanity of the hardware (it's a CHOC12).
#show inter Se7/0/0.6/25:1
Serial7/0/0.6/25:1 is up, line protocol is up
Hardware is C10K CHOC12 One Port
