在端口e0S上检测到校验和错误的TCP数据包
适用场景
- AFF A800
- BMC固件版本10.8.
- ONTAP 9.11.1P8.
- ONTAP 9.11.1P10.
问题描述
- BMC升级到版本10.8.后、端口e0S上检测到TCP数据包校验和错误
system event log输出示例：
::> system event log -event *netif.tcp.conn.bad.checksum*
7/16/2023 10:05:57 node-01 ERROR netif.tcp.conn.bad.checksum: TCP packet with bad checksum detected on port e0S. The packet arrived on connection with source address 10.0.2.1 and destination_address 10.0.2.4.
ifstat -a输出示例：
::> system node run -node node_name -command ifstat e0S
