Is ICX6450 having any stack related problems

[manish_singh_7n]

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.

I searched the release note "FastIron_08030s_ReleaseNotes_v2.1.pdf" for any issues related to stacking. i found below similar issue for model ICX7450.

Is it applicable for ICX6450 too ?

DEFECT000629828 --- 
	Symptom -- In an ICX7450 Switch/Router stacking configuration with the stack port is connected using passive
			cable, sometimes the link statistics for 40G port shows InErrors or CRC errors received.
			
	Condition -- The errors are only seen when the stacking port is connected using passive cable.
        Reported In Release:   FI 08.0.30
        Fixed In Release: FI 08.0.30n

Below are output of some switch commands,
