Core Issue
These are Versatile Interface Processor (VIP) 2 parity errors:
- processor memory parity error exception
- reno read parity error
- I/O controller parity error
- packet memory read parity error
- Protocol Control Information (PCI) bus parity error
- CyASIC parity error
- packet bus write parity error
These are VIP 4 and VIP 6 parity errors:
- processor memory parity error exception
- procmem ECC multi-bit error
- pakmem ECC multi-bit error
- PCI master/slave parity error
- CyAsic parity error
Generally, if a parity error occurs repeatedly, a hardware issue is the cause.
Resolution
When a VIP crash occurs due to a parity error, the troubleshooting steps taken vary depending on which type of parity error has occurred. Perform these steps to address this issue:
- Check the system logs and crashinfo file to determine which type of parity error has occured.
- To view the system log, issue the show logging command.
- To view the crashinfo file, issue the more bootflash: file-url command. To obtain the crashinfo filename, issue the dir bootflash: command.
- Once the parity error type has been determined, refer to the Parity Errors section of Troubleshooting Versatile Interface Processor (VIP) Crashes to determine which hardware is causing the issue.
A crash due to parity error in a VIP does not always mean that the problem is in this VIP.
You may also upload the output of the show tech-support command into the Output Interpreter Tool to display potential issues and fixes.
