Abstract:
When Associate in Nursing oversized style of users ar connected to the H806GPBH/H806GPBD boards, the DDR3 scan operation typically becomes abnormal and conjointly the external DDR3 cache returns cant, causing wrong service packets. As a result, slow web access, dialup failure, and board reset would possibly occur.
Problem Description:
A. Associate in Nursing oversized style of users ar connected to the H806GPBH/H806GPBD boards (this draw back is further likely to be triggered once the number of users exceeds 300, and extra users mean an improved probability for this draw back to occur), traffic is important, or traffic burst happens.
B. Devices use the patches of versions previous V800R008SPC321, V800R010SPC111, V800R011SPC109, V800R012SPC106, and V800R013C00SPC205.
The preceding conditions ar necessary conditions for the matter to occur. However, if these conditions ar met, the problem does not primarily occur (for details, see the premise cause analysis).
Symptom:
Clients connected to the H806GPBH/H806GPBD boards encounter slow web access/dialup failures.
Even board reset would possibly occur.
Location methodology a try of (PMI tool)
If a board involves the matter symptom, upgrade the preventive maintenance review (PMI) tool exploitation the package connected throughout this document and then perform PMI to identify the matter. Install the specified patch
Root Cause:
When packet traffic is important, there is atiny low probability that the interval at that the FPGA reads and writes the DDR3 is simply too short and cannot meet the DDR3 demand. For result DDR3 is became abnormal and packets ar incorrect, inflicting slow web access, dialup failure, or even board reset.
Impact and Risk:
This draw back happens with a low probability and will cause slow web access, dialup failure, and occasional board reset, that is ready to own a sway on live-network services.
Measures and Solutions:
This draw back is triggered typically and should be corrected by resetting the board affected. Because this draw back happens typically and will trigger another DDR3 exception and relevant problems, install the specified patches for the faulty board.
Solutions:
Upgrade patches V800R008SPC321, V800R010SPC111, V800R011SPC109, V800R012SPC106, and V800R013C00SPC105 consequently to resolve the matter.
Warning Expiration:
This warning automatically expires once the trigger conditions are not met.
