nexus 5k maximum number of vpc port-channels

Hi, having trouble getting a straight answer... does anyone know what that maximum number of vpc port-channels I can support on a N5K pair. I see up to 480 in the config guides, but in some marketing slides, it only shows 16. Thanks,

16 is correct.

HTH

I have the same concern and can not get a straigth answer. Do you have the link for reference which says 16? Thank you. As for N7K, beginning 4.1(4), the interface configuration guide says it supports up to 256 vPC per device.

Apparently portchannels are implemented two ways, in hardware and in software.

-  Hardware portchannels contain more than 1 link per N5K - maximum 16 hardware portchannels per N5K

-  Software portchannels contain only a single link per N5K - does not say in my reference below, but I assume you can have as many vpcs as you have ports.
