多个集群网络端口出现CRC错误
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
