适用场景

  • MetroCluster IP
  • ONTAP 9
  • N3K-C322C MetroCluster交换机
  • 集群网络已降级
  • 可能会影响非MetroCluster。

问题描述

  • 重新启动一个或多个MetroCluster交换机后、端口通道中的某些接口将处于暂停状态

示例:

`show interface brief`
...
--------------------------------------------------------------------------------
Ethernet     VLAN   Type Mode   Status  Reason          Speed    Port
Interface                                   Ch #
--------------------------------------------------------------------------------
...
Eth1/15      1     eth  trunk  down   suspended(no LACP PDUs) 100G(D) 10
Eth1/16      1     eth  trunk  down   suspended(no LACP PDUs)  100G(D) 10

  • 如果您重新启动多个交换机并遇到此错误、则可能会遇到集群网络脱脂问题

示例:

Thu Dec 02 12:12:29 +0100 [NodeA-01: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: Large MTU Packet Loss - Ping failures detected between NodeA-01_cluster2 ( 1.2.3.4 ) on PCMSTG201 and NodeA-02_cluster1 ( 1.2.3.4 ) on NodeA-02
