Enabling And Disabling Backplane Diagnostic Packets On The Switch - Extreme Networks ExtremeWare XOS Guide Manual

Troubleshooting
MSMs and I/O modules, monitors memory levels on the I/O module, monitors the health of the
I/O module, and checks the health of applications and processes running on the I/O module. If the
system health checker detects an error, the health checker notifies the MSM.
Backplane diagnostic packets are disabled by default. If you enable this feature, the system health
●
checker tests the data link for a specific I/O module every 5 seconds by default. The MSM sends and
receives diagnostic packets from the I/O module to determine the state and connectivity. If you
disable backplane diagnostics, the system health checker stops sending backplane diagnostic packets.
Enabling and Disabling Backplane Diagnostic Packets on the
Switch
To enable backplane diagnostic packets, use the following command:
enable sys-health-check slot <slot>
BlackDiamond 10K switch—By default, the system health checker tests the packet path every 6
●
seconds for the specified slot.
BlackDiamond 8800 family of switches—By default, the system health checker tests the data link
●
every 5 seconds for the specified slot.
NOTE
Enabling backplane diagnostic packets increases CPU utilization and competes with network traffic for resources.
To disable backplane diagnostic packets, use the following command:
disable sys-health-check slot <slot>
BlackDiamond 10K switch—By default, the system health checker discontinues sending backplane
●
diagnostic packets and returns the polling frequency to 60 seconds on the specified slot. Only polling
is enabled.
BlackDiamond 8800 family of switches—By default, the system health checker discontinues sending
●
backplane diagnostic packets to the specified slot. Only polling is enabled.
Configuring Backplane Diagnostic Packets on the Switch
To configure the frequency of sending backplane diagnostic packets, use the following command:
configure sys-health-check interval <interval>
NOTE
Extreme Networks does not recommend configuring an interval of less than the default interval. Doing so can cause
excessive CPU utilization.
System Odometer
Each field replaceable component contains a system odometer counter in EEPROM. The
command displays an approximate days of service duration for an individual component
odometers
since the component was manufactured.
