LACP Teaming fails with port in "suspended" state on switch

Solution Verified - Updated -

Issue

  • Trying to use two 10GB network adapters in a team configuration with LACP mode does not work. When network is activated, no traffic is possible. Bringing one network card down allows traffic through the other. Activating the card again, makes traffic available on both.
  • Team initially fails, but putting team interface down and up again works.
  • Cisco Nexus Switch shows LACP port-channel slave switchport in (s)uspended state

Environment

  • Red Hat Enterprise Linux 7.2 or earlier
  • Using teamd and libteam Teaming driver with team runner in LACP mode
  • libteam-1.17-6.el7 or earlier
