Usage Guidelines

Figure 1 CloudCampus network diagram

As shown in Figure 1, the new switch, SwitchB, is connected to its upstream device, SwitchA, through two links. When SwitchB and SwitchA negotiate the PnP VLAN, if SwitchA is enabled to inform its downstream device of the need to establish an Eth-Trunk, SwitchB adds two links to the Eth-Trunk and sets the Eth-Trunk mode based on whether the Eth-Trunk mode of SwitchA is LACP.

The auto-negotiated Eth-Trunk can only be Eth-Trunk0, which is reserved on iMaster NCE-Campus and cannot be used by other services.

Example

# Enable the function of transmitting the flag indicating whether to establish an Eth-Trunk to downstream devices.
