适用场景

  • ONTAP 9
  • 交换集群网络

问题描述

  • 多个端口和节点的集群网络端口中的CRC错误增加。::> system node run -node_name -command ifstat -a 示例：
-- interface  e3a  (1 hour, 20 minutes, 0 seconds) --
RECEIVE
Total frames:    123m | Frames/second:   456  | Total bytes:    789g
Bytes/second:    111m | Total errors:    222  | Errors/minute:    0
Total discards:    0  | Discards/minute:   0  | Multi/broadcast:  999
Non-primary u/c:   0  | Errored frames:    0  | Unsupported Op:    0
CRC errors:     222  | Runt frames:     0  | Fragment:       0
...
-- interface  e3b  (1 hour, 20 minutes, 0 seconds) --
RECEIVE
Total frames:    234m | Frames/second:   567  | Total bytes:    890g
Bytes/second:    222m | Total errors:    333  | Errors/minute:    0
Total discards:    0  | Discards/minute:   0  | Multi/broadcast:  888
Non-primary u/c:   0  | Errored frames:    0  | Unsupported Op:    0
CRC errors:     333  | Runt frames:     0  | Fragment:       0
...
  • 交换机端口传输错误、只有一个端口接收错误：
switch_name# show interface Ethernet1/1
RX
62347 input error  0 short frame  0 overrun  0 underrun  0 ignored
 
switch_name# show interface Ethernet1/2
TX
44 output error  0 collision  0 deferred  0 late collision
...
switch_name# show interface Ethernet1/10
TX
6 output error  0 collision  0 deferred  0 late collision
  • 交换机端口"1-1-1-"  LED 持续在橙色-熄灭-绿色之间闪烁
  • 根据network device-discovery show 输出、报告存储错误的所有节点/端口都会连接到同一交换机
