Is any kown Issue with ICX6450 stacking

Question

Hi All,

I'm using ICX6450-48 port 2-stacked switch in a my local environment, all stack ports are 10G. 
I have configured stack ports on both switch units in trunk mode (Trunk1: [1/2/1, 1/2/2], 
Trunk2: [1/2/3, 1/2/4]). 
 
I have observed few link flipping issues on ports 1/2/2 and 1/2/4. In show statistics command, i see some InErrors as well as CRC. I exchanged stack cables even replaced units, but problem still persists.

Is there any issue with stacking in ICX6450. I am using firmware 08.0.30.

What is TAC case? I don't have any idea of it, and how can we open it?

BenBeck · Answer

Can you provide the following:

show stack
show media
show media eth x/y/z (for stack ports)
show stat eth x/y/z (for stack ports)
show version
show run
dm statistic

It may just be a good idea to open a TAC case for this one, but I'm happy to help as well.
