Nexus 1000V: What am I doing wrong?

I've added a host and one VM to the Nexus 1000V and I can't get the VM to ping to save my life. Here is my running config:

Here's a sh vlan output:

Here's a sh int status output:

I've tried over and over the get the port 100 not to be in VLAN 1 in vCenter. What am I doing wrong here? I have the vm settings right also. Any suggestions?

Can we see

"show svs connection"

"show module"

One thing I don't see is a vmk interface assigned to the VEM. You are doing L3 control mode which requires that you assign a vmk interface to the VEM. You will need to create a new veth port-profile with "capability l3control" and assign the vmk interface to that port-profile.

Yeah.There is no module showing up. You need to see a module #3 which would be the ESXi host to show up with "show module"

You need to add a vmknic to the VEM module for everything to work in L3 mode. You can create a new vmk interface or migrate the mgmt vmk interface.

Create a new port-profile like

port-profile type veth vmk-l3

switchport mode access

switchport access vlan #

no shut

vmware port-group

system vlan #

capability l3 control

state enabled

Then assign a vmk interface to that port-profile the module should show up and everything will work.

My recommendation would be to migrate the mgmt vmk interface. If you don't want to do that just be aware of two potential issues.

1. Don't create another vmk interface on the same subnet as your mgmt vmk.

2. You might have to add a static route to the ESXi host so that the new vmk interface can access the mgmt interface of the VSM.
