VXLAN VIB- not able to download vxlan.zip

Hi,

I´m trying to get vxlan working within a vcloud director 5.1 environment. Within vShield manager I tried creating the vxlan under connectivity, by following the procedure provided inhttp://blogs.vmware.com/vcloud/2012/10/vcloud-director-5-1-vxlan-configuration.htmlwhich ended in state "not ready" and error. During this the portgroup is created but no vmknic within this.

I upgraded my networking & security appliance to 5.1.2 as stated here:

http://www.virtualizationteam.com/virtualization-vmware/networking-virtualization-vmware/vcloud-networking-security-5-1-1-create-dvport-groups-but-fails-to-create-vmknic-interfaces.html

After upgrade when I tried vxlan setup its showing "VIB module for agent is not installed on host vShield-VXLAN-Service".

I tried to download VXLAN VIB from

. But when I try to save this vxlan.zip, it shows an error "Unable to download vxlan.zip from vsm-ip".

Am I missing out something here? Anyone have any idea where else　I can get vxlan.zip, or any solution for this problem?

Thanks in advance
