                                     is reporting a high number of observed hardware errors, possibly CRC errors.

  • または

ALERT  vifmgr.cluscheck.hwerrors: Port a1a on node ***** is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).

  • Total errorsTRANSMITセクションのifgrp(この例ではa0a)のみが増加しますが、ifgrpの基盤となる物理ポートごとにエラーは表示されません。
