Host 0 Ecc Single Bit Parity Error Juniper, A minor error is an error that results in the loss of a single packet but is fully recoverable. This issue happens on QFX5k devices running a Junos release which doesnot supports auto detection and correction of parity . The error occurred in the EDAC The 6700 Series modules support a CPU with ECC-protected L2 cache (L1 cache is parity detection capable), which can correct single-bit parity errors without the need to reset. If the message occurs just once or very 为了避免或减少PARITY ERROR造成的丢包，可以采取以下一些措施： 检查交换机的日志，查看是否有PARITY ERROR的提示，以及是否已经被设备自动修复。 如果没有自动修复，可以尝 ECC负责纠错，能够修正1bit的数据。 Parity是同一个data所有比特的异或，在data_in写入的时候进行异或计算得到parity_in，同时写入到RAM中，读出data的得到data_out，对data_out进行 Download manual for Juniper Networks ERX-700, ERX-1410, ERX-1440, ERX-705. ECC errors have two main causes; hardware failure (bad memory, failed board ECC can determine the presence of single-bit errors in program data, including which bit is in error, and correct the data automatically without user intervention. One solution is to upgrade the router to a Junos version, which has '198. 557 qfx5100-48s-6q fpc0 _ This document describes soft and hard parity errors, explains common error messages, and recommends methods that help avoid or minimize parity errors. It is not a hardware error neither a proper warning to contact the manufacturer to request a fix. このドキュメントでは、ソフトパリティエラーとハードパリティエラーについて説明し、一般的なエラーメッセージについて説明し、パリティエラーの回避または最小化に役立つ方法を推奨します。 This is the only SRAM parity error that looks like a transient condition and does not compromise packet forwarding with simulations in-house. xrif [3].
