N5k & N2k .......

[dave_ryan]

Hi...

so i was looking at the N5k and just wonder what the maximum distance is for a connection to a N2k??

is this something similar to stacking 3750's where the connection is made with the stack wise cable, therefore they have to be relatively close

or is it just a simple uplink ?? where the distance is governed by the cable/sfp???

Regards

D.

Hi David, a question I can actually answer .  The N2K's connect to the N5Ks by a 10 Gb connection that is configured on the 5K as a FEX (Fiber Extender) port.  Essentially the when the 2K comes up it's just a dumb device with no config (very similar to an LWAPP AP); after boot it will look to the 5K for the correct code and any configuration it needs to load.

Hi Dave,

• Distance between Cisco Nexus 2000 Series Fabric Extender and Cisco Nexus 5000 Series Switch: Up to 3 km (300m for FCoE traffic)

taken from the following 2k data sheet:
