Hi.
I am trying to look for Nexus 5K config when the nexus2K FEX is dual-homed into it.
What will be the configuration on both 5K especiall the pinning?
Assuming one N2K 10G port is connected to N5K-1 and another N2K 10G port connected to N5K-2?
N5Ks are also configured as dual-sided vpc with two N7K.
thanks

Assuming interface E1/7 is connected to the N2K on both N5Ks:
interface e1/7
channel-group 100
interface po 100
swithcport mode fex
fex association 100
vpc 100
For the host interface, the same port needs to be configured on both N5Ks.
N5K-1
interface e100/1/1
switchport access vlan 123
N5K-2
interface e100/1/1
switchport access vlan 123

N5k-1 & N5k-2 config:

No pinning is needed if you want all traffic to load balanced between the fabric interfaces. Default setting is fine.

I am looking at the topology below:
Since the N2K is dual homed, which ports will be assigned to N5K-1 and which ports to N5K-2?

Hi Allan,
What is the code that you are running on the N5K.
If you have NXOS 5.3(1)N1 or above you could make use of enhanced vPC. In this case the servers could be connected to a single FEX or two with NIC1 in FEX1 and NIC2 in FEX2. You have more deployment options.
