EMS 报告"ClusterSwitchConnectionDegraded_Alert"

Fri Dec 20 19:11:41 +0100 [CLUSTER-01: cshmd: hm.alert.raised:alert]: Alert Id = ClusterSwitchConnectionDegraded_Alert , Alerting Resource = CLUSTER-01 raised by monitor ethernet-switch

在系统健康警报中可以看到相同的警报

Cluster::*> system health alert show Node: node Alert ID: ClusterSwitchConnectionDegraded_Alert Resource: node Severity: Major Indication Time: Thu Mar 06 15:03:16 2025 Suppress: false Acknowledge: false Probable Cause: Only one cluster switch, "switch", has been discovered to be connected to the cluster ports of node "node". If a cluster connection was not discovered, but the expected cluster switch is listed in the output of "system switch ethernet show", it indicates that the node is not currently receiving discovery information about the missing switches.

但是，从设备发现中，我们可以看到这两台交换机

Cluster::> network device-discovery show

Node/     Local Discovered

                       Ethernet1/10 N9K-C9336C-FX2
       e0b   ClusterSW2(YYYYYYY)
                       Ethernet1/11 N9K-C9336C-FX2

                       Ethernet1/10 N9K-C9336C-FX2
       e0b   ClusterSW2(YYYYYYY)
                       Ethernet1/11 N9K-C9336C-FX2

从 system switch ethernet show 中，我们只能看到一个交换机的条目

Cluster::*> system switch ethernet show -instance

                  Device Name: ClusterSW2
                   IP Address: 192.xx.x.9
