Application of Eth-Trunk

Application of Eth-Trunk

As shown in Figure 2-11, traffic of services with different priorities is sent to the core network through the UPE and PE-AGG. To ensure the bandwidth and reliability of the link between the UPE and PE-AGG, an LAG, Eth-Trunk 1, is established.

Figure 2-11  Link aggregation networking

You can determine the working mode for the Eth-Trunk according to the following situations:

  • If devices at both ends of the Eth-Trunk support LACP, the LACP mode is recommended.

  • If the device at either end of the Eth-Trunk does not support LACP, you must use the manual load balancing mode.

QoS can be implemented on an Eth-Trunk as a common interface. At both ends (UPE and PE-AGG) of Eth-Trunk 1, traffic shaping, congestion management, and congestion avoidance can be performed for outgoing traffic, ensuring that packets of high priorities are sent in a timely manner.
