BES switches are not visible via CDP on one or more MetroCluster IP nodes

Last Updated:

Applies to

  • MetroCluster IP
  • Broadcom BES 53248
  • Health Monitoring (HM)


  • In a MetroCluster IP configuration using BES-53248 switches the following HM alert may come up even if all connections to the Switch are online and cluster peer ping reports that all peers are reachable:

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". 

  • Nodes doesn't get CDP/ISDP information on cluster ports, connected to BES switch 53248:

  • Command system health alert shows error

Cluster2B                                     One or more nodes are not connected to both cluster switches.
  • Devices only visible from node A, Node B not listed:
