ONTAP 9

问题描述

  • 广播域设计为包含一组属于同一第2层网络的端口
  • 创建广播域后、可能会为其分配一个或多个LIF、但前提是LIF可能会故障转移到广播域中的任何端口、并需要相同的网络连接
  • 如果广播域包含来自多个VLAN的端口、并且LIF故障转移到广播域中不提供相同网络连接的端口、则该广播域可能会导致服务中断
    • 要查看广播域中某个lf的lf故障转移目标、请执行以下操作:
      • 命令行:::> network interface show -failover -broadcast-domain <broadcast domain>
      • AutoSupport部分: network-interface.xml
        • 子部分: failover targets
在某些情况下、可以在一个广播域中混合使用带VLAN标记的端口和未带标记的端口。由用户根据客户端网络配置来确定。如果未标记VLAN的端口连接到的交换机端口配置为可以访问VLAN、则可能没有问题描述。这在e0M端口中最常见、因为无法在此端口上配置VLAN标记。
  • 由于存储控制器无法查看此配置、因此它可能会从此存储控制器或通过AutoSupport发出警告消息或警报

示例: 

[node-02: vifmgr: vifmgr.reach.noreach:notice]: Network port e0M on node node-02 cannot reach its expected broadcast domain Default:vlan20. No other broadcast domains appear to be reachable from this port.

  • 如果已验证配置、则可以忽略这些消息
