    Traffic flow: NIC teaming and trunk failover
    If failure anywhere on the link toward the upstream switch, the NIC on blade server does not know about the failure and may
    continue to send traffic toward the top switch, which will discard the traffic. The Trunk Failover feature addresses this issue.

    Teamed Active/Standby
    If the switch fails in such a way that the link toward the Blade server goes down, or NIC fails, Blade server can sense this and redirect traffic out the other NIC toward the bottom switch. NIC Teaming can take care of this without the need for trunk failover.

    Traffic flow: Trunk failover example 1
    If Po1 goes down, trunk failover takes over and shuts down internal downstream defined port(s)
    This alerts NIC Teaming to an upstream failure at which point Teaming switches to the other path out of the server
    This example shows a single VLAN to Teamed NICs, It is possible to also carry multiple VLANs to the Teamed NICs

    Traffic flow: Trunk failover example 2
    If only one port channel goes down, spanning tree allows backup path to other port channel
    If both port channels go down, trunk failover takes over and shuts down internal downstream defined port(s)
    This alerts NIC Teaming to an upstream failure at which point it switches to the other CIGESM
    This example shows a single VLAN to Teamed NICs, It is possible to also carry multiple VLANs to the Teamed NICs
