The PortChannel on the Cisco Nexus 5000 Series access switches becomes active, indicating that the LACP
negotiation is functioning between the upstream vPC system and the Cisco Nexus 5000 Series:

Flags: D - Down P - Up in port-channel (members)
I - Individual H - Hot-standby (LACP only)
s - Suspended r - Module-removed

The PortChannel on the Cisco Nexus 7000 Series Switch also becomes active because of the LACP negotiation:

If the PortChannel ports are suspended, a mismatch occurred in the PortChannel ports between the switches that are
supposed to bring up the PortChannel. For example, a vPC on the Cisco Nexus 7000 Series is configured with ports
that individually connect to two different PortChannels on the Cisco Nexus 5000 Series.
Alternatively, if the access-layer ports are not configured for a channel, the Cisco Nexus 7000 and 5000 Series will
operate normally with spanning tree. If the ports on the Cisco Nexus 5000 Series are configured in passive channel-
group mode and the Cisco Nexus 7000 Series ports are not configured for PortChannels, the Cisco Nexus 7000 and
5000 Series run spanning tree again on those ports.
