All or 50% of from-network packets arriving at a front panel port are dropped in hardware prior to delivery to tenant(s) running on the CPU. Packet loss is caused by CRC errors on an internal bus connecting two hardware components leading to eventual failure of the bus.
Total loss of from-network to CPU packets on r5900, r5800, and r5600 appliances, and either total loss or loss of 50% of from-network to CPU packets on r10900, r10800, and r10600 appliances. The r4800, r4600, r2800, and r2600 appliances are unaffected.
Issue occurs randomly, but is most commonly seen soon after bootup when packets first start to be handled by fastL4 hardware acceleration, hardware per-virtual server syn cookie protection, or AFM hardware protection.
Reboot the appliance and disable fastL4 acceleration, per-virtual syn cookie hardware protection, and AFM hardware protection before re-enabling ingress traffic.
This issue has been corrected.
