Re: OT: Nexus deployment with 802.3ad LACP team

We are using the management vrf for the keepalives. otherwise its the
default vrf. We didnt want to get too fancy with the config as we dont
need it. Another member on the list replied and said that the 2K's
currently do not support this yet. I will have to call Cisco and get
more info.

Thank you all for your help!!
