Description (partial)

Following the reload of a N5K vPC peer, its port-channels will be in a suspended state until the default delay restore and auto-recovery timers elapse. During this time, certain downstream devices may show their corresponding port-channel members as up/up in LACP 'I' (Individual) state with STP forwarding. This has been observed with CBS and 3750, however, IOS devices will not hash traffic on LACP Individual links.

LACP vPC and the reload of either N5K.
