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.
Depending upon your platform, when enabling backplane diagnostic packets, the following defaults
apply:
●
BlackDiamond 10808 and BlackDiamond 12804 switches—The system health checker tests the packet
path every 6 seconds for the specified slot.
●
BlackDiamond 8800 series switch—The system health checker tests the data link every 5 seconds for
the specified slot.
Usage Guidelines
Configure the system health checker with guidance from Extreme Networks Technical Support
personnel.
The system health checker tests I/O modules and the backplane by sending diagnostic packets. On the
BlackDiamond 10808 and the BlackDiamond 12804 switches, 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.
NOTE
Enabling backplane diagnostic packets increases CPU utilization and competes with network traffic for resources.
The system health checker continues 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.
BlackDiamond 10808 and BlackDiamond 12804 Switches Only.
If you enable backplane diagnostic packets
on a slot, the polling timer changes from its current value to the backplane diagnostic packet interval
slot
Specifies the slot to participate in sending backplane diagnostic packets.
