Overview
This section recommends that the health and configuration check must be performed on the switch before performing an upgrade to avoid potential issues.
A Nexus health and configuration check is an automated diagnostic service that
-
analyzes Nexus switch logs to identify issues and provides recommendations
-
checks critical configurations such as virtual Port Channel (vPC), multicast, and Layer 3 uplinks, and
-
ensures best practices and detects inconsistencies in complex environments.
We recommend performing a Nexus health and configuration check before performing an upgrade. The benefits include identification of potential issues, susceptible Field Notices, security vulnerabilities, and missing recommended configurations. For more information about the procedure, see Perform Nexus Health and Configuration Check.
