Commands for Status Monitoring and Statistics
enable sys-health-check
enable sys-health-check slot <slot>
Description
Enables backplane diagnostic packets on the specified slot.
Syntax Description
Default
Polling is enabled, backplane diagnostic packets are disabled.
Usage Guidelines
The system health checker tests I/O modules and the backplane by sending diagnostic packets every 6
seconds. Additional checking for the validity of these packets is completed by performing a checksum.
By isolating faults to a specific module or backplane connection, the system health checker notifies you
of a possible hardware failure.
System health check errors are reported to the syslog. Syslog output includes the slot number where the
problem occurred, the loopback packet ID number, and a notification that the MSM did not receive the
last packet. If you see an error, please contact Extreme Networks Technical Support.
When you enable backplane diagnostic packets on a slot, the polling timer changes from its current
value to the current backplane diagnostic packet interval configured on that slot. For example, if the
frequency of sending backplane diagnostic packets is 7 seconds, the polling value is 7 seconds.
NOTE
Enabling backplane diagnostic packets increases CPU utilization and competes with network traffic for
resources.
The system health checker will continue to periodically forward test packets to failed components.
To configure the frequency of the backplane diagnostic packets, use the
configure sys-health-check
interval
command.
Example
The following command enables backplane diagnostic packets on slot 6:
enable sys-health-check slot 6
