Hi,

I am new to nexus 1000V, the setup is as follows, UCS Chassis with 4 Full width blades connected to 2 FI 6248UP.

each FI has uplink to a n5k (no VPC).

is there any template for configuring the nexus 1000v? how to configure the port-channel?

thanks.

Hello,

We recommend to use mac pinning  ( " channel-group auto mode on mac-pinning ")  when N1KV is used on UCS blades.

Following doc provides good overview on best practices.

Hello Shadow,

On UCS, N1k port-channels are always configured with mac-pinning.  You do not mention how many adapter cards are present on the blade.  For a basic setup where all adapters carry the same traffic you would have 4 vNICs.  2vNICs on adapter 1 connecting to A & B fabrics.  Repeat on adapter 2.  Do not configured fabric failover.  On the N1k, add all four vNIC to the same port-profile.  For more complex setups such as dedicated vNICs for vMotion, iSCSI, etc, you may want more vNIC or less.

The port-channel configuration on the fabric interconnects has no relationship to using N1k.  Since the N5k will not be doing vPC, the best configuration would be a two links from each FI to each N5k.  Example: FI-A would have a link to N5k-1 and another to N5k-2.

This document contains a sample configuration for N1k on UCS:
