Why does CSHM attempt a SSH connection to a cluster switch

Last Updated:

Applies to

  • ONTAP 9
  • Cluster, Storage and MetroCluster IP Switch Health Monitor (CSHM)


  • As part of normal operation, CSHM connects via SSH to the switch to collect the displayed banner information, but CSHM does not actually log in to the switch
    • The banner is parsed to obtain RCF file and version information
    • The SSH connection function cannot be disabled
  • When switch log collection is enabled, public key-based SSH connections are established by CSHM to collect switch meta-data and log information
