Cisco N1K -L3 mode configured but vemcmd-health check show "supports L2 only" and port is blocked

[aqiqulhoda]

hi,

I am trying to setup Cisco N1K on a vCenter 5.5 using L3 mode, however it shows on the ESX host that it only supports L2 and the port group shows as blocked by Admin.

In the basic setup I have used L3 mode in the Ethernet port-group I am using trunk mode and in the veth port-group I am using capability L3control .

I am looking for a solution where I am going wrong?

I got this resolved after doing two things:

a) switch(config-svs-domain)# control type multicast

&

b)VEM modules will not register to the VSM before a vmkernel interface (vmk) is migrated to a Layer3 Control capable port profile.

(Once a vmk was migrated to this switch - it all lighted up for me !)
