Connect Nexus 2332 to a 5672up

[willsupport]

Good Morning,

my customer bought those models of data center switches.

My questions is:

Cisco, for the 5672 provides an adapter that convert a qsfp 40g to a sfp 10g, so i can use my 10g optic modules on this switch.

Unfortunately on the 2332, this adapter is not compatible, and now i have a serious problem, cause i must use all the 40g ports to do redundant links but i won't have scalability for the future.

Can i connect the 40g port of the 2332 to the 10g port of the 5672, and be able to estabilish a link?

Thanks,

Alessandro

Hi,

Can i connect the 40g port of the 2332 to the 10g port of the 5672, and be able to estabilish a link?

The 2332 FEX comes only with 10Gig uplibks only? So, you would have go 10Gig to 10Gig.

Hi,

the 2332 has 4x40g ports, i need to connect them to the 10g ports 5672up.

Could it work? 40g 2332tq -> 10g 5672up?

You can use a QSFP adapter to convert from 40 to 10.

On the 2332tq i can't use that adapter.

The 5672up comes with 6 40Gig ports.  Can't just use 40 to 40 straight?

The topology is composed of:
- 2 5672UP
- 4 2332TQ

If i use redundant links between all the devices, i won't have free ports for future 2332 or others devices

The topology is composed of:
- 2 5672UP
- 4 2332TQ

Even if you connect them fully meshed, you will still have 2 extra 40 gig in each 5672 to use in the feature.

Nope, i use all the ports on the 5672

I don't know but maybe you can use a 40GQSFP to four 10G SFP+ breakout cable...?

It could be a solution, but the cable is only 10 meters long

I need to know if a 40g optic can communicate with a 10g optic.
