Ok, I'm at my wits end.
I've followed every post in this thread about QSFP breakout cables. I've got a Dell P8T4W, which appears to be just a longer 27GG5.
I've unstacked (no stack-trunk 1/2/1 to 1/2/2, no stack-trunk 1/2/6 to 1/2/7)
I've reseated connectors, but only one of 4 channels seem to come up.
They're in 1/2/2-1/2/5.
sh media says they're 40GE-Passive Copper
show interfaces brief e 1/2/1 to 1/2/10 says 1/2/2, 1/2/4, and 1/2/5 are down, despite being connected to servers.
1/2/2 and 1/2/3 are in a LAG group (that host is up) and 1/2/4 and 1/2/5 are in a LAG group (that host is not).
What am I missing here?
SOLVED: After unstacking, you need to reload the config, otherwise, only one of the ports comes up. Everything is 100% functional after that.
