Usage Guidelines
This command allows you to configure MSM response to a failed health check. The command applies to
all MSMs in the system. If you do not configure a separate alarm-level response for MSMs, they use the
same alarm response that is configured for the rest of the system.
The system health checker tests I/O modules, MSMs, SMMi modules, and the backplane by forwarding
packets every 4 seconds. Additional checking for the validity of these packets is completed by
performing a checksum.
By isolating faults to a specific module, the system health checker prevents corrupted packets from
being propagated to the CPU, upper layer modules, or the rest of your network. If you observe a
failure, please contact Extreme Technical Support.
Depending on how you have configured the system health checker, failed system health checks may
generate critical error messages in the syslog, and may also send a trap and/or shut down the system.
The system health checker will continue to periodically forward test packets to failed components. If
auto-recovery is configured, the system will attempt to automatically reset the faulty module and bring
it back online.
In ExtremeWare versions prior to 6.2, you cannot use both mirroring and the system health checker at
the same time. If you configure mirroring with the system health checker enabled, the health checker
