We just upgraded our core switch to a Nexus 9396, which is connected to dual UCS 6248 FI's and also individually to some Dell R710's with a dual 10Gb Ethernet card. When connecting these standalone servers with an etherchannel VPC, the management IP address goes up and down and some hosts can talk while others can't. If I leave one port disabled, it works fine. However, as soon as both are enabled, connectivity goes down. These ESXi servers are on a standard license, so distributed switches are out of the question. I did enable an eval license and setup a vDS using the enhanced LACP and that works great, it just won't work as a standard etherchannel with a standard virtual switch. The connectivity to the 6248's is also working without any issues running in LACP. Below is the configuration:
Nexus SW01:
interface Ethernet1/5
description ESX vPC Member
switchport mode trunk
channel-group 202
no shutdown
interface port-channel202
description ESX
switchport mode trunk
vpc 202
Nexus SW02:
interface Ethernet1/5
description ESX vPC Member
switchport mode trunk
channel-group 202
no shutdown
interface port-channel202
description ESX
switchport mode trunk
vpc 202
ESXi configuration is a standard switch with "Route based on IP hash" and both adapters active. Am I missing something? Is this setup not supported? Any help/advice would be greatly appreciated.
Thanks!
