EFPs and EtherChannels
You can configure EFP service instances on EtherChannel port channels, but EtherChannels are not supported
on ports configured with service instances. Load-balancing on port channels is based on the MAC address or
IP address of the traffic flow on the EtherChannel interface.
This example configures a service instance on an EtherChannel port channel. Configuration on the ports in
the port channel are independent from the service instance configuration.
