Problem Description

When the EGS2 board of OSN3500 device and the EFS board of METRO1000 device are configured with EPL service, the service is not available and the test frames are not available when the FCS field of the Ethernet single boards on both sides is set to " FCS32 " by default; the service is available and the test frames are also normal when the FCS field is set to "no". When the FCS field is set to "no", the service can be opened and the test frames are normal.

Warning message

None

Processing

1. Analyzing the data related to the EGS2/EFS single board, we found that a large number of zero-packet packets were received by vctrunk18 in the black box of the EGS2 single board when the single board check field was defaulted to " FCS32 " at the site:

bb1.log 2008-12-12 12:14:33 VCTRUNK 18 occurs zero pkt.

bb1.log 2008-12-12 12:14:44 VCTRUNK 18 occurs zero pkt.

bb1.log 2008-12-12 12:14:54 VCTRUNK 18 occurs zero pkt. bb1.log 2008-12-12 12:14:54 VCTRUNK 18 occurs zero pkt.

2, thus basically confirm the problem in the EGS2 single board PL215 chip, confirmed that the EGS2 single board PL215 chip in the 208 version of the FCS32 enable case, will produce zero packets; FCS field set to "no" case will not produce zero packets.

Solution:

FCS field parameter is set to "no";

Root cause solution:

Upgrade the EGS2 single board PL215 chip logic version to version 210 and later.

Root Cause

1、EGS2/EFS single board software problem;

2、Suspect EGS2/EFS single board PL215 chip FPGA logic version problem because GFP encapsulation protocol is realized in PL215 chip.
