CRC errors stack ports exos 16.2.5.4

CRC errors stack ports exos 16.2.5.4

Good afternoon. I am using a project stack of 4 extreme switches (2-x670 vim 4-40G4X module, 2-x460 v80 module). I am constantly seeing an increase in CRC errors on stack ports. Modules were replaced by me. Updated switch version to 16.2.5.4 patch1-20. However, the growth of CRC continues. The debug hal settings have also been changed. CRC errors continue to grow. Please help me fix the problem.
After upgrading the switch version, the second switch in the x670 stack (role Backup) is always lit indicating on the ports as active, even if the port is forced down.

The whole problem is that multicast traffic passes through STACK

Hello Stephan.Today QSFP cables have been replaced which are used in the stack. The situation is similar, the growth of errors continues.

Hello Andrei,

 

normally green == 10G and blue == 40G. You should see these on the left upper side in the module, there should be a control led in green and blue.

If you see 10G there is maybe a missconfiguration  and both switches need to have the same port speeds. In addition von 10G you need fanout cables.

Please check the port config.
