Hello,
I have a pair of n5k, with 10* n2k dual homed.
I have a Po for a server connected on 2 different n2k, but when I try to add vPC ID the Nexus reject my command.
NEX-A# sh port-ch sum
201 Po201(SD) Eth LACP Eth1/23(D) Eth1/24(D)
303 Po303(SD) Eth LACP Eth104/1/11(D) Eth104/1/12(D) Eth105/1/11(D)
Eth105/1/12(D)
The command works for n5k ports but not n2k :
NEX-A# sh run int po201
interface port-channel201
description SERV-00-01
switchport access vlan 112
speed 10000
vpc 201
NEX-A(config)# int po303
NEX-A(config-if)# vpc 303
ERROR: Operation failed: [vPC already exists]
Here is my show vpc, no vpc 303, but one ID per port and a total of 508 vpc whereas I configured only 2 vpc :
NEX-A# sh vpc
Legend:

There will be an internal port-channel created for enhanced VPC. you dont need to explicitly set a VPC ID. in fact, you cant.
please check the output of "show vpc brief" and you will see the port-channel listed there.

Hi;
You share the output of "show vpc brief" of primary switch, can you verify on secondary N5K switch also may be vPC id 303 is assigned to port-channel.
Thanks & Best regards;

Hi,
You're right, here is the output with auto generated ID :
111662 Eth110/1/47 down* Not Consistency Check Not -
Applicable Performed
111663 Eth110/1/48 down* Not Consistency Check Not -
Applicable Performed
262446 Po303 down* Not Consistency Check Not -
Applicable Performed
262454 Po311 down* Not Consistency Check Not -
Applicable Performed
262455 Po312 down* Not Consistency Check Not -
Applicable Performed
It's an error from my part, we need to use vPC ID on Po, when Fex are single homed.
Thank you all.
