CRC Errors Detected -在集群端口上检测到较高的CRC错误
适用场景
- ONTAP 9
- FAS/AFA系统
- 集群交换机
问题描述
- 一个集群网络端口每小时报告大量CRC错误。
示例：
[Node-01: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e0a on node Node-01 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).[Node-01: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: CRC Errors Detected - High CRC errors detected on port e0a node Node-01- 多个系统运行状况警报指向 问题描述的源。
示例：
NodeIfInErrorsWarnAlertThe percentage of inbound packet errors of node "node_name-01" on interface "e0a" is above the warning threshold.ClusterIfInErrorsWarn_AlertThe percentage of inbound packet errors of switch interface "switch_name-01/Slot: 0 Port: 2 25G - Level" is above the warning threshold.The percentage of outbound packet errors of switch interface "switch_name-01/Slot: 0 Port: 1 25G - Level" is above the warning threshold.- 所有节点的集群LIF都会向一个集群LIF报告总的数据包丢失事件：
[Node-01: vifmgr: vifmgr.cluscheck.droppedall:alert]: Total packet loss when pinging from cluster lif Node-01_clus2 (node Node-01) to cluster lif Node-02_clus2 (node Node-02).
[Node-01: vifmgr: vifmgr.cluscheck.droppedall:alert]: Total packet loss when pinging from cluster lif Node-02_clus1 (node Node-01) to cluster lif Node-02_clus2 (node Node-02).
- 一个端口收到并传输到另一个端口的错误：

System health subsystem show命令可以将 主板和/或交换机运行状况报告为“已分级”并触发NodeIfInErrorsWarnAlert。
