Blocking Non VMKNIC port Veth10 with capability vxlan - Nexus100v

I am trying to configure VXLAN on my 1000v .  Everything seems ok then when I put a machine on the system uplink profile that I have configured with capability vxlan and a vmknic with a routable IP the test machines on the two ESX servers cannot ping each other

port-profile type vethernet system-uplink-vxlan

  vmware port-group

  switchport mode access

  switchport access vlan 3893

  capability vxlan

  no shutdown

  state enabled

2012 Apr 18 14:39:20 n1k-ictc-test1 %VIM-5-IF_DETACHED: Interface Vethernet11 is detached

2012 Apr 18 14:39:20 n1k-ictc-test1 %ETHPORT-5-IF_DOWN_NON_PARTICIPATING: Interface Vethernet11 is down (Non participating)

2012 Apr 18 14:39:25 n1k-ictc-test1 %VIM-5-IF_CONFIG_PURGE_AUTO: Configuration on interface Vethernet11 has been auto purged (port-profile changed)

2012 Apr 18 14:39:25 n1k-ictc-test1 %VIM-5-IF_ATTACHED: Interface Vethernet11 is attached to Network Adapter 1 of VXLAN2 on port 10 of module 5 with dvport id

2012 Apr 18 14:39:25 n1k-ictc-test1 %ETHPORT-5-IF_UP: Interface Vethernet11 is up in mode access

When I look on the ESX server same error that the port is being blocked.
