336 ExtremeWare XOS 11.0 Command Reference Guide
Commands for Status Monitoring and Statistics
configure sys-health-check interval
configure sys-health-check interval <interval>
Description
Configures the frequency of sending backplane diagnostic packets and the polling interval. If backplane
diagnostic packets are disabled, this command configures the global polling interval on the switch.
Syntax Description
Default
• If backplane diagnostics packets are enabled on a particular slot, the default for sending packets and
for polling is 6 seconds on that slot
• If only polling occurs, the default polling interval is 60 seconds (
interval
*10 seconds)
Usage Guidelines
The system health checker tests I/O modules and the backplane by forwarding backplane diagnostic
packets every 6 seconds. Additional checking for the validity of these packets is completed by
performing a checksum.
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.
Use this command to:
• Configure the amount of time it takes for the packets to be forwarded and returned to the MSM
• Modify the global polling interval on the switch
To enable backplane diagnostic packets, use the
enable sys-health-check slot <slot>
command.
With backplane diagnostic packets enabled on a specific slot, the
interval
option specifies the
frequency of sending backplane diagnostic packets and the polling of ASIC counters on that slot. For
example, if you specify an interval of 9, backplane diagnostic packets are sent and polling occurs every
9 seconds for the enabled slot only.
You can also use this command to modify the global polling interval on the switch. With only polling
enabled, the
interval
option specifies the frequency of polling ASIC counters on all slots. Therefore, if
you configure the interval to 8 seconds, the polling interval is updated to 80 seconds (
interval
*10
seconds).
interval Specifies the frequency of sending backplane diagnostic packets and polling
the ASIC counters.
• If backplane diagnostic packets are enabled on a particular slot, the default
value for sending diagnostic packets and polling the ASIC counters is 6
seconds on that slot.
• If only polling occurs (this is the system default), the default value is 60
seconds. The polling interval is
interval
*10 seconds.
