问题描述
- 在多个数据端口的 IFSTAT -A 中看到的 CRC 错误：
-- interface e4b (1 day, 10 hours, 2 minutes, 12 seconds) --
RECEIVE
Total frames: 130k | Frames/second: 1 | Total bytes: 14931k
Bytes/second: 122 | Total errors: 122 | Errors/minute: 0
Total discards: 0 | Discards/minute: 0 | Multi/broadcast: 50163
Non-primary u/c: 0 | CRC errors: 122 | Runt frames: 0
Fragment: 0 | Long frames: 0 | Jabber: 0
Length errors: 3 | No buffer: 0 | Xon: 0
Xoff: 0 | Pause: 0 | Jumbo: 0
Noproto: 0 | Error symbol: 0 | Illegal symbol: 0- 多个端口的 EMS 消息：
vifmgr.cluscheck.hwerrors:alert]: Port e3b on node-4 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped) vifmgr.cluscheck.hwerrors:alert]: Port e4b on node-3 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped) vifmgr.cluscheck.hwerrors:alert]: Port e3b on node-3 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped)
- 端口都连接到同一对数据交换机。
- 无交换机配置问题。
- 一个数据端口没有 CRC 错误：
-- interface e4b (1 day, 10 hours, 2 minutes, 43 seconds) --
