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:
