适用于

  • Brocade 交换机
  • Cisco 交换机
  • ONTAP 9.10 及更高版本

回答

概述
  • FPIN(交换矩阵性能影响通知)帧是由交换矩阵端口传输的通知帧,用于通知给定终端设备其区域中另一个端口的特定情况。 

这些情况包括:

  • 降低性能的链路完整性问题
  • 丢弃帧通知
  • 拥塞问题(本地和远程)

因此,许多端口问题可以比以前在更大程度上得到快速诊断。 这也可能引发各种类型的恢复操作。

需要从 Fabric 上的终端设备获取初步的注册帧序列,以表明其对此机制的支持。 

配置
  • 除了版本控制之外,无需在 NetApp 存储设备上执行任何配置操作。
示例
FPIN 注册状态,如 Brocade 命令行中所示
