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.
