Syntax Description
slot
Default
Polling is enabled, backplane diagnostic packets are disabled.
Depending upon your platform, when enabling backplane diagnostic packets, the following defaults
apply:
BlackDiamond 10K switch—The system health checker tests the packet path every 6 seconds for the
●
specified slot.
BlackDiamond 8800 family of switches—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 10K switch, 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
command.
