I'm trying to get a link up between a 9500-32C and Meraki MS425. I have a 10G single mode optic in the Meraki and a QSFP-4X10G-LR MPO optic in the 9500 with a single mode breakout cable. I can't get a link to come up. When I do a show inventory on the 9500 it sees the 4 breakout interfaces as QSFP-40G-SR4. It seems like the switch thinks this is a multimode optic. I reached out to fiberstore and they said this is just a display issue and that it should work fine but I can't get a link to come up. The 9500 is running version 16.12.4 so it supports breakout and it did split the interface out. I used port 27 so I now have hu1/0/27/1-4. Any ideas?
