Description (partial)

In a Nexus 6001, the QSFP based module 2 takes 2-3 minutes longer for it to come online after module 1 comes online. Depending on how servers are connected/configured, this can cause traffic to be blackholed if network devices are connected to the module 2 uplinks.

Seen after a switch reboot/reload.
