交换机升级或重新启动后、端口显示为暂停(无LACP PDU)
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
- 重新启动集群交换机后、 端口通道中的某些接口处于暂停状态
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
- 如果交换机的ISL端口受到影响、则事件日志会报告以下警报：
[Node-01: cshmd: hm.alert.raised:alert]: Alert Id = ClusterIfIslDownWarn_Alert , Alerting Resource = Cluster-sw2(FOXXXXXXXXX)/Ethernet1/43 raised by monitor ethernet-switch
[Node-01: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: ClusterIfIslDownWarn_Alert[Cluster-sw2(FOXXXXXXXXX)/Ethernet1/43].
