Re: OT: Nexus deployment with 802.3ad LACP team

The uplink vPC to the 6509's is working. The VSS consists of 2 6509's
which are multi-chassis portchannel to the 2 5K's (which are using
vPC) My concern is at the host level. If i configure the port-channel
to the servers using LACP the port channel says its down and the port
itself is in Individual mode (I). If i configure it with just this
command (as stated in the quick start guide for vPC)

channel-group 10

The port-channel shows up but I do not see any increase in throughput
from the server.

My question is do i even need to configure anything if the servers are
doing NIC teaming?

Thanks for your response.
