I. Phenomena:

recently, a large number of optical fiber switch port disconnection alerts have been received from the monitoring platform errdump alert events found VSwitch system due to software error panic reset, the phenomenon is as follows:

further analysis panic the reason for the reset, analyze the switch Dump log, vSwitch occurs panic the reason is A SI C chip reporting PC I E link communication error, the phenomenon is as follows:

logs are recorded multiple times. P CIE bus A SI C an exception occurred in the chip communication link and was finally triggered. panic reset and repair.

2. Solution:

VSwitch A SI C chip and PC I E the switch occurs due to link communication problems. panic reset, required replace the whole switch to completely solve the problem.

III, conclusion:

this switch, because ASIC caused by Chip reset Processor rebooted -Software Fault: ASSERT the problem needs to be completely solved by replacing the whole machine.
