pvlan (promiscuous port) not permitted on etherchannel

This is probably an often-asked question:  I've read in the 7K v5.0(2) NX-OS docs, the 6500 12.2SXF/SXH IOS docs and the 5K docs that the pvlan feature  cannot co-exist with etherchanneling on the same uplink.  This would assumedly include promiscuous trunk ports.

This seems so counter-productive and self-defeating.  Especially where the 7K vPC feature is cfg'd requiring LACP etherchannels from the single switch into both 7Ks.

What am I missing here?  Is there a work-around short of new dedicated links?  The cost of the 10G optics for that approach is prohibitive.  Is it possibly on the road-map for some future upgrades?

Maybe I could configure an unconditional port-channel with no protocol, no negotiation?  I'm waiting on the vDC licensing to let me direct-connect the lab 5Ks.

Thank you,


Ken Johnson
