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
