Re: Nexus 5K vPC Peer link 1Gb over OM2 Fiber

It will but not all ports are 1/10G. Some are 10G only.

The 2 peers will be roughly 340m between each other and will be connected via an OM2 (50/125) MMF. The standard SFP-10G-SR SFP+ only supports a max distance of 26m over OM2 so is out of the question. I see a SFP-10G-LRM will support up to 220m and was hoping would stretch to 340m as these figures are usually on the conservative side. The SFP-10G-LRM is not mentioned in the SFP compatibility matrix for the Nexus 5K but I have seen some postings of people using it.
