在一个或多个 MetroCluster IP 节点上,无法通过 CDP 看到 BES 交换机
适用场景
- MetroCluster IP
- Broadcom BES 53248
- 运行状况监控( HM )
问题描述
-
在使用BES-53248交换机的MetroCluster IP配置中、即使与交换机的所有连接均已联机并
cluster peer ping
报告所有对等方均可访问、也可能会出现以下HM警报:
Cluster-A::*> system health alert show
Node: Node-A2
Resource: Node-A2
Severity: Major
Indication Time: Mon May 10 17:59:20 2021
Suppress: false
Acknowledge: false
Probable Cause: One or more nodes are not connected to both cluster switches.
Possible Effect: If one cluster switch fails, "Node-A2" might lose
access to the cluster.
Corrective Actions: Verify that the switch "Node-A1" is connected
to the node "Node-A2".

节点无法获取有关连接到 BES 交换机 53248 的集群端口的 CDP/ISDP 信息:
- 命令
