Switches Are Connected Across a Transmission Device
As shown in Figure 3-14, two switches are positioned far away from each other. In order for the switches to communicate, a transmission device needs to be deployed between them. In addition, to enhance link bandwidth and reliability, link aggregation is configured between the two switches. To achieve this, the following conditions must be met:
- The switches at both ends must use link aggregation in LACP mode.
- The transmission device between the switches must be configured to transparently transmit LACPDUs.
