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

5548 and 5596 yes. 5010 and 5020 no. Same with 7K, some linecards are 1G only, some are 10G only, and some are dual rate.

>>> The reason I ask, and I know this is a long shot, is that we are planning to install 2 Nexus 5500 at our core/distribution layer and use the vPC feature. 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.
