Hybrid Stack SG350X 48p & SG350XG 2F10 crash

Hi,

 

the 2F10 (unit2) crashed today. The upstream links to 2*SG550XG were dead till rebooting the whole stack.

 

Is this a know issue? Btw. the stack is for availability reasons....

 

FW: 2.3.5.63

Hi,
Based on this output I can suggest a couple of things:
1. You can see that UDLD threw an error message which means that it detected a unidirectional link. This could be caused by a bad cable/SFP so you can try to change those.
2. You are currently running firmware version 2.3.5. The latest firmware for the SG350xx is 2.4.0 so I can suggest to upgrade.
