Licensing Requirements and Limitations for Logical Interfaces
Involved Network Element
Other network elements are not required.
Licensing Requirements
A logical interface is a basic feature of a switch and is not under license control.
Feature Support in V200R019C10
All models of S7700 series switches support logical interfaces.
For details about software mappings, visit Hardware Query Tool and search for the desired product model.
Feature Limitations
- For Layer 2 interfaces, only hybrid and trunk interfaces support Ethernet sub-interface configuration. After a Layer 2 interface is switched to a Layer 3 interface using the undo portswitch command, the interface supports Layer 3 Ethernet sub-interface configuration.
- After an interface is added to an Eth-Trunk, you can only configure sub-interfaces on the Eth-Trunk, but not on the interface.
