問題

1つのクラスタネットワークポートから、1時間ごとに大量のCRCエラーが報告されます。

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

複数のシステムヘルスアラートが問題のソースを参照しています。

例：

NodeIfInErrorsWarnAlert

The percentage of inbound packet errors of node "node_name-01" on interface "e0a" is above the warning threshold.

ClusterIfInErrorsWarn_Alert

The 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.

すべてのノードのクラスタLIFから、パケット損失イベントの合計が1つのクラスタLIFに報告されます。

[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).

一方のポートで受信され、もう一方のポートに送信されたエラー：
