The Ethernet switch health monitor (CSHM) is responsible for ensuring the operational health of Cluster and Storage network switches and collecting switch logs for debugging purposes.
Important notes for configuring CSHM in a MetroCluster IP configuration
This section contains the generic steps for configuring SNMPv3 and log collection on Cisco, Broadcom, and NVIDIA SN2100 switches. You must follow the steps for a switch firmware version that is supported in a MetroCluster IP configuration. Refer to the Hardware Universe to verify the supported firmware versions.
In a MetroCluster configuration, you configure health monitoring on the local cluster switches only.
For log collection with Broadcom and Cisco switches, a new user should be created on the switch for each cluster with log collection enabled. In a MetroCluster configuration, this means that MetroCluster 1, MetroCluster 2, MetroCluster 3, and MetroCluster 4 all require a separate user to be configured on the switches. These switches do not support multiple SSH keys for the same user. Any additional log collection setup performed overwrites any pre-existing SSH keys for the user.
Before you configure the CSHM, you should disable unused ISLs to avoid any unnecessary ISL alerts.
