I have a Arista 7050S-52: 52 x 1/10GbE SFP+ ports and I’m trying to figure out the best way to uplink it with our main/building switch, which is an Arista 7150S with four QSFP+ 40G ports.

I had thought to take the last four SFP+ ports (49/50/51/52) and bundle them together into one of the 7150’s 40G but it seems that isn’t an option with the 7050S line of switches.

What would you recommend as the best way to connect the 7050S to the 7150S? Just a simple 10G cable? Or is there some more clever configuration I can do?

Hi Cindy,

All 52 ports on 7050S are 10G ports. You can use a 4×10 splitter cable and bundle them in a 4×10 port-channel. You can have QSFP+ port on 7150S as 4x10G. Unfortunately, you won’t be able to run a port on 7050S for more than 10G and so port-channel bundling is the only option for higher bandwidth uplink.
