Usage Guidelines
This command allows you to configure the switch's reaction to a failed health check.
The
configure sys-health-check alarm-level
commands are mutually exclusive; configuring an alarm-level disables previously configured
auto-recovery, and configuring auto-recovery overrides the previously configured alarm-level setting.
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.
To configure a separate system health checker response for just the MSMs, use the
sys-health-check alarm-level msm
By isolating faults to a specific module or backplane connection, 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.
