Eth-Trunk
The Eth-Trunk consists of Ethernet links only.
The Eth-Trunk technique has the following advantages:
– Increased bandwidth: The bandwidth of an Eth-Trunk is the total bandwidth of all
member interfaces.
– Improved reliability: When a link fails, traffic is automatically switched to other
available links. This ensures link reliability.
