Load-Balancing

EtherChannel load balances based on 'flows'.

A flow is a communication between two nodes in the network.

Frames in the same flow will be forwarded using the same physical interface.

If frames in the same flow were forwarded using different physical interfaces, some frames may arrive at the destination out of order, which can cause problems.

You can change the inputs used in the interface selection calculation.

Input that can be used:

• Source MAC,

• Destination MAC,

• Source AND Destination MAC,

• Source IP,

• Destination IP,

• Source AND Destination IP.
