Diagnostics
Table 7 describes the behavior of the switch if you run diagnostics manually on “i” series switches using
the run diagnostics CLI command with the normal option. The behavior differs based on the
hardware configuration, the mode selected (online or offline) using the
configure sys-health-check
CLI command, and the number of errors to be detected.
