适用场景

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

问题解答

概述
  • FPIN (Fabric Performance Impact Notification、网络结构性能影响通知)帧是由网络结构端口传输的通知帧、用于通知给定终端设备其区域中另一个端口的特定情况。 

这些条件包括:

  • 导致性能下降的链路完整性问题
  • 丢弃的帧通知
  • 拥塞问题(本地和远程)

因此、许多端口问题可以比以前更快地得到诊断。这也可能导致执行各种类型的恢复操作。

网络结构上的终端设备需要一个初始注册帧序列、以表明它们支持此机制。 

配置
  • 除了版本控制之外、不需要在NetApp存储设备上执行任何配置操作。
示例
FPIN注册状态、因为它显示在Brocade命令行上
