On Nexus 6001s, running two different NX-OS versions (6.0(2)N2(5), 7.0(8)N1(1)). show lacp neighbor output looks inconsistent. Partner Flags says neighbor is sending fast LACP PDUs, but Partner Port State says 0x3d, which decodes to slow LACP PDUs.

Output above is from one switch (running the 6.0-series software), but I have another switch for comparison running the 7.0-series software with the same conflicting information.
Is this a bug in the output? Is the connected device really sending fast LACP PDUs, and NX-OS is reporting this, but the end device is lying in its flag status? Connected device is a NetApp of some flavor; I don't know model or OS version.
Thank you kindly for any input on this.
