We run all Juniper QFX in our DC and cannot be happier. Solid stuff.

Subject: Re: 1G/10G BaseT switch recommendation

The Juniper QFX 5120-48T has the 48x10G RJ45s you're looking for and has QSFP+/28 100G capable ports that can each be broken out into 4x25G (via DAC or MPO).

They can be licensed to add OSPF/BGP and their brand is ubiquitous enough that API support should be no problem on most management platforms.

I think you'll have a tougher time finding native SFP28 25G uplink ports for a 10G switch as it's mostly seen as a server-facing port speed alternative alongside 10G, rather than an uplink for 10G; the oversubscription ratio between 48x10G and 4-6x25G is quite high when you account for at least 2N redundancy on the uplinks.

Hello everyone,

I’m looking for recommendations from the community on 48x10G RJ45/4-6 SFP28 (uplink ports) switches that people actually like working with.

Features are VPC or non-vendor specific equivalent, L2/L3 BGP/OSPFv3, ACLs, functional CoPP and some sort of API to manage them. [the CLI would work, my lib can handle most Networking OS CLIs anyway]

My problem point is coming from the RJ45 requirement, most vendors have one switch that they sell that is RJ45 at 10G or at the most one in each line (enterprise/datacenter) and they seem to be almost an afterthought. [probably because SFP28 is better in every way if you are already using fiber at the endpoint] sadly, we are not.

I just want to make sure I am not excluding any vendors from my research.

I appreciate any suggestions or recommendations. Can even keep it off-list if you want.

Thanks,
-Drew
