Explanation
This message indicates a new CPU Cyclic Redundancy Check (CRC). It prevents bad packets from
being passed up to the CPU.
Action
If this error is seen only once in the log, no action is necessary.
If you are using ExtremeWare 6.2.1 (or earlier), use the
show log and show tech-support commands,
capture the output, and contact Technical Support to troubleshoot the problem.
If you are using ExtremeWare 6.2.1 (or later), system health check can be enabled. If the system check is
enabled, three consecutive occurrences of the above error triggers automatic recovery of the port or the
module. If the software can detect the error, it will correct the error. However, if the software is unable
to detect the error, it will take the module offline.
NOTE
If you are using ExtremeWare 6.2.1 or later, run the pktScan utility to identify and correct the problem.
If you are using ExtremeWare 6.2.2 (or later), you can take the module either offline or keep it online
even if automatic recovery fails.
