In this a port-channel gets the following error: pm_get_port_channel_counters: Failed to parse port counter stats ret_val (0x1) This leads to some of the following port-channels having mismatched counters the following show interface counters command: <pre> show interface port-channel101 is trunking ... 34 discards,68 errors 34 invalid CRC/FCS,0 unknown class 0 too long,0 too short 1708222326436 frames output,3253511056753324 bytes 0 discards,0 errors show interface counters port-channel101 ... 4 discards, 8 errors, 4 CRC/FCS 0 unknown class, 0 too long, 0 too short 1658590719503 frames output, 3147629413173316 bytes 0 discards, 0 errors </pre> The above seems to indicate the number of input discards went from 34 to 4 while the show tech-support was underway.
