Thanks for the suggestion. This was a Cogent connection and forcing it to 1Gb brought the link up right away.

yep I rolled the fiber initially -- ended up having to force link speed to 1Gbps

interestingly enough the COM transceiver does appear to have same branding and sticker layout. It also does result in a product match when running the S/N against the Cisco SN check. Maybe COM can indicate refurb? Thanks for the input, I think I've got some next steps to try for troubleshooting.

I did try using the existing transceiver which did not work, but I did not try forcing it to 1Gb. Good idea, I'll give that a go.

I'm currently doing an equipment refresh on a telco distribution switch and am unable to get link lights on an SFP downlink from one of the service providers. Current 3850's are using GLC-SX-MMD-COM transceiver and we purchased an MA-SFP-1GB-SX for the Merakis. My question is what is the equivalent Meraki transceiver if we are using the wrong one? I'm able to find info on a GLC-SX-MMD transceiver but the one in production has a -COM at the end. Does that just signify compatibility with 3rd party vendors? Any help is much appreciated.
