C3850-NM-4-10G question

[Jagan1976]

Hi guys,

I have a 3750x switch with C3KX-NM-10G network module.

Currently it has 2x1Gb and 1x10Gb uplinks to other floors.

Now I need to add another 10G uplink to a new floor.

As I understand the C3KX-NM-10G can only support upto 1x10G and 2x1G uplinks.

Thinking of upgrading to 3850 switch and using C3850-NM-4-10G instead. However, can this network module support 2x1G and 2x10G uplinks? (combination of SFP and SFP+)?

I checked the Cisco sites and this information is not clear.

Not all models of 3850 can support C3850-NM-4-10G.  And yes, all 4 ports support SFP+.

Hi Leo, 

But can the module support 2*SFP 1G + 2*SFP+ 10G concurrently?

C3850-NM-4-10G can support up to 4 optical modules: From 4 x SFP to 4 x SFP+ (or any combo).
