Community,
I know this seems like a very amateur type question but I did want to ask before I implement the changes.
We have two Nexus 9Ks that have a multitude of 2K FEXs uplinked to them in "straight through" mode. My task is to uplink a server that uses 4 NICs/HBAs to the FEXs. Two links from the server will go to FEX ports 104/1/21 - 22 on FEX-A and the other two will go to FEX ports 104/1/21 - 22 on FEX-B. The channel protocol will be LACP. My question is this:
In what order should I do this? Does it matter? I just want to make sure im doing this correctly. The vPC peer link is already configured and there are already several servers linked up the same way, I just personally have never done this before.
I was thinking of doing it in the following order:
Nexus9K-1(Config)# interface eth104/1/21 - 22
Nexus9K-1(Config-if)# switchport mode trunk
Nexus9K-1(Config-if)# speed 1000
Nexus9K-1(Config-if)# duplex full
Nexus9K-1(Config-if)# channel-group 30 mode active
Nexus9K-1(Config-if)#exit
Nexus9K-1(Config)# Interface po30
Nexus9K-1(Config-if)# vpc 30
Nexus9K-2(Config)# Interface eth104/1/21 - 22
Nexus9K-2(Config-if)# switchport mode trunk
Nexus9K-2(Config-if)# speed 1000
Nexus9K-2(Config-if)# duplex full
Nexus9K-2(Config-if)# channel-group 30 mode active
Nexus9K-2(Config-if)#exit
Nexus9K-2(Config)# Interface po30
Nexus9K-2(Config-if)# vpc 30
Does anyone see any issues with this order? Thanks for the feedback.
Chris.

Hi Chris,
The "vPC Example Configuration" section of the following link covers the sequence of steps needed to configure vPC and LACP in detail
