ExtremeWare 7.5 Command Reference Guide 705
configure sys-health-check alarm-level
configure sys-health-check alarm-level [log | system-down | traps |
default]
Description
Configures the alarm response for the system health checker.
NOTE
This command is available only on the Alpine and the Summit “i” series switches.
Syntax Description
Default
The default alarm level is log.
Usage Guidelines
This command allows you to configure the switch’s reaction to a failed health check.
The system health checker tests I/O modules, 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, SMMi, 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.
The
alarm-level
and
auto-recovery
options are mutually exclusive; configuring an alarm-level
disables auto-recovery, and configuring auto-recovery overrides the alarm-level setting.
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
will indicate that it has been disabled by sending a message to the syslog. In ExtremeWare 6.2 or later,
this restriction does not apply.
