Extreme Networks ExtremeWare XOS Command Reference Manual page 606

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Commands for Status Monitoring and Statistics
To enable backplane diagnostic packets, use the command.
enable sys-health-check slot <slot>
With backplane diagnostic packets enabled on a specific slot, the option of the
interval configure
command specifies the frequency of sending backplane diagnostic
sys-health-check interval
packets. For example, if you specify an interval of 9, backplane diagnostic packets are sent every 9
seconds on only the enabled slot.
NOTE
Extreme Networks does not recommend configuring an interval of less than the default interval. Doing this can cause
excessive CPU utilization.
BlackDiamond 10808 and BlackDiamond 12804 Switches Only. If backplane diagnostic packets are
disabled, you can use this command to configure the global polling interval on the switch.
When you enable backplane diagnostic packets with the
enable sys-health-check slot <slot>
command, the option also specifies the polling frequency on that slot. For example, if you
interval
specify an interval of 9, backplane diagnostic packets are sent and polling occurs every 9 seconds for
only the enabled slot.
You can also use the command to modify the global polling
configure sys-health-check interval
interval on the switch. With only polling enabled, the option specifies the frequency of polling
interval
on all slots. Therefore, if you configure the interval to 8 seconds, the polling interval is updated to 80
seconds ( *10 seconds).
interval
If backplane diagnostic packets are enabled on a slot and you modify the polling interval on the switch,
the new interval value takes precedence. For example, if you configure the interval to 7 seconds, the
polling interval is updated to 70 seconds on all slots with backplane diagnostics disabled. On the slot
with backplane diagnostic packets enabled, backplane diagnostic packets are sent and polling occurs
every 7 seconds.
To return to the default of sending diagnostic packets every 6 seconds and the system polling every 60
seconds, specify 6 for the .
interval
By default, the system health checker always polls and tracks the ASIC counters that collect correctable
and uncorrectable packet memory errors, checksum errors, and parity errors on a per ASIC basis. You
must enable the backplane diagnostic packets feature to send backplane diagnostic packets.
BlackDiamond 8800 Series Switch Only. By default, the system health checker always polls the control
plane health between 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.
You must enable the backplane diagnostic packets feature to send backplane diagnostic packets. 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.
