Which of the following is NOT a method of EtherChannel load balancing?

EtherChannel load balancing is a technique used to distribute traffic evenly across the different links in an EtherChannel connection to optimize network performance and utilization. The methods of load balancing involve analyzing specific parameters of the packets being sent across the network interfaces.

The source MAC address method identifies the source MAC address of the packets and uses this information to determine which link within the EtherChannel should carry the traffic. The source/destination IP method combines both the source and destination IP addresses to create a hash that helps in distributing the traffic. The destination IP method focuses solely on the destination IP address for making load balancing decisions.

While these methods are utilized for the effective distribution of load within an EtherChannel, the protocol type method is not a typical method used for load balancing in this context. Protocol type would refer to the type of communication protocol being used, but it does not contribute to the decision-making process regarding how traffic is distributed across the available links in an EtherChannel. Therefore, it does not fit the framework of effective load balancing strategies.
