This article may include metadata, visibility, validation state, and related support guidance.
适用场景
- FAS2552
- SFP-H10GB-CU3M 直连铜缆（ DAC ）
- 光纤扩展器（ FEX ）
- Cisco Nexus 5000 交换机
问题描述
- 存储每小时报告以下消息：
vifmgr.cluscheck.crcerrors: Port on node is reporting a high number of observed hardware errors, possibly CRC errors.
- 这一点也反映在 IFstat 命令的输出中：
Cluster::> system node run -node <node name> -command ifstat
-- interface e0d (18 days, 14 hours, 50 minutes, 56 seconds) --
