1000v "channel-group auto mode active"

I'm trying to connect a pair of Nexus 5532UP's, with vPC, to a Nexus 1000v.  I'm running 4.2.1.SV1.4a. When I add the server's physical NICs to the dVS in vCenter, they fail to come up on the VSM and report link down (NoPortProfile).  If I take "channel-group auto mode active" out of the port-profile, or use "mode on" the links come up, but I want to use vPC on the Nexus 5k's.

'show run port-profile uplinks':

port-profile type ethernet uplinks

  vmware port-group

  switchport mode trunk

  switchport trunk allowed vlan 12,13,14,15

  channel-group auto mode active

  no shutdown

  system vlan 12,13,14,15

  state enabled

'show accounting log':

Thu Sep  1 22:17:57 2011:update:ppm.7239:admin:configure terminal ; interface Ethernet3/5, Ethernet3/7 ; channel-group auto mode active (FAILURE)

(the rest of the config in the port-profile report "SUCCESS" in the log)

So, what's the problem?  What should I look at next?  Downgrading the 1000v software?

Ah, so feature commands aren't unique to the hardware models.

'feature lacp' was missing. Thanks.

After enabling lacp feature, I had to re-apply the port-profile using "no shut" command on each interafce.
