asked on VMWare -Cisco physical switch configuration for etherchannel
i have a dell R710 connected via dual 10Gbps connections to a Cisco nexus 5548 switch. I am trying to configure the switch to use both 10Gbps ports in a port channel. when I apply the port-group 204 command on both the end ports, I lose connectivity to the host. What am I missing or could it be something on the vSwitch?

channel-group auto mode on mac-pinning
In my enviornment I am only connecting to 1 switch (redundant switch is not there yet). This command is only used on VPCs from what I understand to tell the 1000v to pin the mac to a specific port rather than balancing traffic between ports. We enabled this setting on the individual ports and the uplink port-profile. both ports then were allowed to be channeled.
