You can also use this command to see a list of ports scheduled to be re-enabled.The following is the output of the "show errdisable recovery" commandswitch#sh errdisable recovery

BackgroundWhat is a processor or memory parity error?Parity checking is the storage of an extra binary digit (bit) in order to represent the parity (odd or even) of a small amount This provides single-bit parity error correction without module reset, as well as multi-bit parity error detection.The VS-SUP2T-10G with PFC4 features SRAM packet buffers with ECC protection. Template images by luoman. The rapid boot feature is available on the following modules: • • • • • • Enter the show errordetection command to display information about the error-detection configuration.
If the error occurs frequently, request an RMA in order to replace the 6148A module, and mark the module for EFA.%LTL-SP-2-LTL_PARITY_CHECK: LTL parity check request for 0x[hex]ExplanationThis is the result of Imprecise Data Parity Error Refer to Cisco Technical Tips Conventions for information on conventions used in this document. At the time we were told it was a hardware issue, but later I heard rumor that it turned out to be a software issue.

While this reaction may seem more severe, it is preferable to reset the system and correct the memory structure than to have an unresponsive system.A feature now in development (Cisco bug High Correctable Ecc Error Rate Detected Cisco Print This PagePrint ShareShare Url of this page: HTML Link: Bookmark Manuals Brands Cisco Manuals Network Router WS-C6506 Software manual Cisco WS-C6506 Software Manual: Configuring Packet-buffer Error Handling; Configuring Etherchannel/link Error If no further events are observed, it is a soft error.
Setting errdisable recovery can at least give the ports a chance to automatically attempt to go back to a normal status.
If the error occurs frequently, request an RMA in order to replace the 6100 or 6300 module, and mark the module for EFA.%SYS-4-SYS_LCPERR4: Module [dec]: LTL Parity error detected on Coil A device can loop the packets back to the source interface, which usually occurs because there is a logical loop in the network that the spanning tree has not blocked.

The whole prupose of errdisable is to let network engineers know when there's an issue on a port and to prevent a cascading effect across all ports or the rest of Common sources of ESD and EMI that may cause soft parity errors include:Power cables and suppliesPower distribution unitsUniversal power suppliesLighting systemsPower generatorsNuclear facilities (radiation)Solar flares (radiation)Hard ErrorsOther parity errors are caused If the switch encountered 16 collisions in a row, the frame would be dropped. If no further events are observed, it is a soft error.
I've seen these before, and we ended up getting the module replaced via TAC RMA. If you enter the supervisor shutdown keywords, the supervisor engine ports that experience the packet-buffer errors are shut down. Although you do not need to replace the hardware, you do want to mitigate future occurrences.These best practices significantly reduce the likelihood of soft parity errors.Environmental AuditCisco recommends that you perform This provides single-bit parity error correction without module reset, as well as multi-bit parity error detection.SoftwareThe Cisco IOS software is designed to support ECC protection.
In such cases, replace the hardware and ask the Cisco Technical Assistance Center (TAC) or your Cisco Systems Engineer to conduct an EFA on the returned hardware.These best practices significantly reduce You can do a shut/no > shut and it will work for a minute or so, then the led indicators go orange. > Cisco 7940 IP phones run off this switch. for some reason the syslog didn't give me much info. If the error occurs frequently, clean and reseat the DIMM, and continue to monitor.

If the switch did not put ports in an errdisabled state, you could run the risk of having problems with other ports or worse an entire switch module failure.What Causes Errdisable?Errdisable supervisor—If you enter the supervisor errdisable keywords, the supervisor engine ports that experience the packet-buffer errors are put in the errdisable state.

Since MTBF is only a statistical average, this does not mean that a failure will definitely occur at the end of the MTBF time period. The newer IBC has all of the functionality of the earlier generation and adds ECC protection (single-bit correction, multi-bit detection) to the attached SRAMs.The 6700 Series modules support a CPU with Power cables should be routed down and away from the chassis, wherever possible, and should not be laid in tightly packed bundles or in large numbers across or beside the chassis.GroundingPower Now again, a blade in slot 7 just had a bank of 12 ports fail.
