Documentation Update; Ironware Software Release 02.7.02A For Brocade Bigiron Rx Series Swtches - Brocade Communications Systems PowerConnect B-RX Release Note

Documentation Update

The system monitoring service (SYSMON) feature was introduced in the 02.6.00c patch release. This
feature monitors the hardware in the system to detect, report, and in some cases isolate and recover
hardware errors in the system. When an error or event occurs, SYSMON generates Syslog messages,
which must be reported to Brocade Technical Support.
In the 02.7.02a patch release, the following enhancements were added:
1. A read and write test was added to detect failed Switch Fabric Module (SFM) FE failures. A Syslog
message is generated to indicate a SFM FE failure.
2. The performance of ingress DRAM CRC detection was improved. This detection now has two
methods to detect errors; an interrupt routine is used to detect these errors quickly and will trigger a
shutdown of the failed TM. Long term polling has been added to detect low rate CRC errors which
will be reported with a Syslog message.
3. TM blocked (stuck) buffers can now be detect and recovered from egress. This process generates a
Syslog message.
Note: As a result of the extended monitoring enhancements, any marginal hardware may be reported as
defective.
Furthermore, The default behavior for TM register monitor action has been changed. The shutdown
action is now enabled by default. Enter no sysmon tm reg shutdown command to disable this action.
The following table presents the examples of Syslog message generated by SYSMON for the events that
trigger them.
