Cisco Nexus 9K (NXOS 9.3) Dual-homed FEX (FEX-AA) configuration

[John.Mayer]

Hi everyone

Just have a quick question about configuring the DUal-Homed FEX with Nexus 93180, for every host which connects to the fex interfaces (like servers which have only one connection to n2k-2248) is there any ways to sync the running config between both parent nexuses or I have to config 103/1/1 on both Nexus switches.

Note:

fex 103 already registered on both parent switches

interface Ethernet1/49
switchport
switchport mode fex-fabric
fex associate 103

channel-group 103
no shutdown

interface port-channel103
switchport
switchport mode fex-fabric
fex associate 103
vpc 103

show vpc 103

vPC status

here is my scenario

Hello @John.Mayer,

You need to manually provide FEX port’s configuration consistency among vPC domain. You will need to configure the interfaces on both Nexus switches separately, including the port-channel and the associated interfaces.
