Hello B.B

Kindly fina attached file.

Hello B.B

The protocol at VMware LACP

I think i must make port-channel Active 

 

Appreciate your help

I am confused here or am i reading wrong,

 

1. First, you mentioned Hyper-V

2. Second, you comment VMWARE? ( do you have vSwitch configured inside VMWARE, is this Exsi or VMWARE Workstation?

 

Can you explain how is your setup? Physically connected to where?

 

I have also requested below output from switch. ( i do believe,  you lost connection due that Port-channel not come up ?)

 

show vpc

show port-channel summary interface port-channel 75

Looks good to me as per Switch side, so when you enable vPC is the port-channel still up ?

 

Make sure you have correct setup on vSwitch side.
