ifstat输出中的vifmgr.cluscheck.crcerrors警报报告长帧

适用场景

• ONTAP 9
• FAS/AFA平台

问题描述

1. 在的输出中可以看到长帧 ifstat。示例：

-- interface  e1d  (5 days, 13 hours, 44 minutes, 30 seconds) --
RECEIVE
 Total frames:    438k | Frames/second:     1  | Total bytes:    32232k
 Bytes/second:     67  | Total errors:   32047 | Errors/minute:     4 
 Total discards:    0  | Discards/minute:    0  | Multi/broadcast:   561k
 Non-primary u/c:    0  | CRC errors:      0  | Runt frames:      0 
 Long frames:    32047 | Length errors:     0  | Alignment errors:   0 
 No buffer:       0  | Pause:         0  | Jumbo:         0 
 Noproto:        0  | Bus overruns:     0  | LRO segments:     0 
 ...

1. 根据ONTAP版本、可以在EMS中记录以下任一事件
   • [Node1: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e1d on node Node1 is reporting a high number of observed CRC errors.
   • [Node1: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e1d on node Node1 is reporting a high number of observed hardware errors, possibly CRC errors.
   • [Node1: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e1d on node Node1 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).
2. 此端口已配置MTU 1500
3. 在交换机端、交换机端口未接收任何长帧、但正在传输这些帧：

switch# show interface eth0/10
Ethernet0/10 is up
  RX
   0 jumbo packets  0 storm suppression bytes
 TX
  32047 jumbo packets
