Why does an S series switch generate an error message during link aggregation configuration
When adding an interface of an S series switch (except the S1700) to an Eth-Trunk, ensure that the interface is of the same type as the other member interfaces and the interface does not have any configurations. Follow these guidelines: 1. Each Eth-Trunk contains a maximum of eight member interfaces by default. 2. An Eth-Trunk cannot be added to another Eth-Trunk. 3. Member interfaces of an Eth-Trunk must use the same Ethernet type and rate. Interfaces that use different Ethernet types and rates cannot join the same Eth-Trunk. For instance, GE interfaces and FE interfaces cannot join the same Eth-Trunk, but GE electrical interfaces and GE optical interfaces can join the same Eth-Trunk.
