适用场景

  • ONTAP
  • Nexus N9K-C9336C-x2
  • 参考配置文件( RCF )

问题描述

  • 新安装后、集群交换机端口会增加错误: 

$ ssh admin@10.10.10.150 "show interface counters errors non-zero"

  • 发现集群交换机端口上的MTU设置为1500:(示例端口) 
switch# show int e1/7
Ethernet1/7 is up
admin state is up, Dedicated Interface
  Hardware: 1000/10000/25000/40000/50000/100000 Ethernet, address: b8a3.771c.048

 MTU 1500 bytes, BW 40000000 Kbit , DLY 10 usec
  reliability 255/255, txload 1/255, rxload 1/255
 
  • 发现即使在写入擦除和重新加载之后也未应用RCF
`switch# config terminal`
`switch(config)# banner motd #`
`switch(config)# interface breakout module 1 port 1-3 map 10g-4x`
`switch(config)# interface breakout module 1 port 4-6 map 25g-4x`
Error: Breakout maps of 25g-4x and 50g-2x are not supported on 40G transceivers
...
...
`switch(config)# interface e1/1/1-4, e1/2/1-4, e1/3/1-4, e1/4/1-4, e1/5/1-4, e1/6/1-4, e1/7-34`
                                               ^
Invalid range at '^' marker.
`switch(config)# inherit port-profile CLUSTER`
...
...
 
  • 错误将持续到 RCF 行完成:
 
% Invalid command at '^' marker.
`switch# end`
`switch# end`

Copy complete.
