Re: nexus 3k with servers

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

Re: nexus 3k with servers

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.

HAve you checked on the Server connecting the Console and Monitor, what is the status on Esxi  side ?

 

Can you post you esxi vswitch screen shot to understand better on this issue. we do not see for now any issue on switch side.
