Nexus 7K question regarding N7K-F132XP-15

[ningche]

Dear expert,

I work in Cisco lab and doing performance demo on mobile packet core solutions. We have a Next 7000 10 slot chassis with 3 32 port 10G modules(N7K-M132XP-12L). Since N7K-M132XP-12L limit total bandwidth to 80G, we want to get several new 32 port 1G and 10G F module(N7K-F132XP-15). I have a few questions through:

1, Can N7K-F132XP-15 and N7K-M132XP-12L co-exist in same chassis? My feeling is "yes" but want to confirm.

2, N7K-F132XP-15 can have 230G bandwidth to switch fabric given 5 switch fabric installed, how does 230G distribute to each goup of 8 ports(or 4 ports maybe)? I know for N7K-M132XP-12L, group of 4 ports share 10G, any such limitation for  N7K-F132XP-15?

3, N7K-F132XP-15 appears to be less expensive than N7K-M132XP-12L even it has more bandwidth, do I loss something compare to N7K-M132XP-12L?

Thanks a lot

Hi Ning

I can help out on a few, so to answer:

1) Yes, you can have both N7K-F132XP-15 and N7K-M132XP-12L in the same chassis

2) I'm not sure on this one, will have to look into some specs on it.  Perhaps someone else knows, feel free to chime in

3) Keep in mind the N7K-F132XP-15 (F1 module) is not very comparable to N7K-M132XP-12L(M1 module).  F1 modules are L2 only, so no routing is done on the linecard itself.  F1 can do fabricpath where as M1 cannot.

Depending on what you want to do with the module the M1 may be a better choice.  If you are looking at pure L2 then F1 is fine, and then you can even take advantage of FabricPath, however if you want to do any L3 you need the M1 modules.

Hope that helps
