Break out port issue. I've configured the switch to use the two 40G ports for stacking and the other two QSFP ports as breakout ports. Stacking works great. I've setup 2/2/2 to 2/2/3 as tagged ports and each one connects to one of two servers. Same with ports 2/2/7 to 2/2/8. They connect perfectly at 10Gb and the two activity lights for the ports are all on and working perfectly.
The other four (ok, 2 times 2) break out ports are setup as untagged on a specific VLAN for management (overkill, but I have the ports, so...). And they do NOT work at all. To verify the ESXI side of things (and to have management access), I have configured one of the front 10Gb ports on the same VLAN and connected it to the primary server in place of the breakout cable. It connects and runs perfectly fine.
Here is the port configuration for the non working breakout port (2/2/4) and working front port (2/3/5):
The stack configuration from show run:
Finally, show interface brief unit 2:
Once more, I suspect it is something simple and obvious that I am missing. My gut says it has to be in the breakout port configuration, but they APPEAR to be the same as the working front 10Gb port, so I'm doubting my gut right now. Is there an issue with trying to run some of the breakout ports tagged and others untagged?
Any help would be greatly appreciated, even if you have to start the reply with "Hey knucklehead, did you notice ...!"
