6450 stack w/8030n issues?

I'm working on setting up a 4 unit stack of ICX 6450-48s. Firmware installed is 8.0.3n - Routing. I am getting a continuous stream of the following entries to the console port:

T=17h5m20.1: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h5m57.7: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h7m59.8: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,
T=17h8m9.4: 1/2/1 goes down. delete direction 0, trigger election
T=17h11m20.3: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h13m56.9: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,
T=17h17m9.5: 1/2/1 goes down. delete direction 0, trigger election
T=17h17m38.5: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,

In addition the input errors and CRC numbers are steadily increasing.

I'm using the standard 1m stacking cables.

Does anyone know what might be happening? Is there a different version of firmware (earlier/later) that I should be using instead?

Any help is appreciated.

If a stack port flaps or loses communication, it will trigger an election. You need to clean up the stack ports if you are seeing errors. What is the media type? Have you tried other cables? Can you gather the following:

show stack
show stat e 1/2/1 e 1/2/3 e 2/2/1 e 2/2/3 (assuming these are the stack ports)
dm statistic
show media
show log

Looks like layer 1 port flaps to me. Left most column is layer 1 (physical) transitions:

123-0-0-0(1/2/1)
31-0-0-0(1/2/3)

Have you tried other cables?

I only have the 4. One of my future troubleshooting steps was to try them one at a time. I'll try it sooner rather than later and report the results.

Sounds good. It's interesting that all of the connections show CRC errors. Bad batch of cables maybe?

Well, I tried each of the 4 cables with different switch/port parings, and the CRC errors occur for each test. So it could be bad cables, bad stacking ports, or still possible bad firmware. I'lll have to try some earlier code to see if the CRC errors are still present.

Pretty unlikely the code has anything to do with it. Maybe run a 'clear stat' and 'dset' (clears dm statistic) and monitor those prior commands. Maybe there is just one culprit. That would help narrow it down.

I have been running a clear stat command and monitoring those numbers after the stack renegotiates. On the current units connected, over the past hour+, one interface is showing 7826 CRC /1121 InErrors, and the matching interface is showing 18226 CRC / 2281 InErrors.

I want to rule out firmware prior to opening up a RMA case.

I just remembered that I have a pair of 6430-24s that I can try the cables on as well. If the errors follow, that would at least rule out unit hardware issues.

Todd,

Ever find anything on this one?

Sorry for the delay. The cause was incorrect cables. I was inadvertently sent 1Gig stacking cables, not the required 10Gig. Surprising that the interfaces came up with the incorrect cables. Lots of errors, but still, I would not have expected the interfaces to still be active.
