F5OS allows you to manually type in non-existent interfaces of type "ethernetCsmacd" when adding an interface component. The system later prohibits you from deleting this non-existent interface while the type is ethernetCsmacd.
The configuration contains a non-existent ethernet interface with no actual activity. Attempting to delete the interface from the Partition CLI will result in the following error : Partition-1(config)# no interfaces interface 1/1.1 Warning: Some elements could not be removed due to NACM rules prohibiting access. From the Partition GUI The Network-> interfaces Page will show blank "There are no items to show in this view."
User-triggered command for non-exposed interface type.
Delete the non-existent interface. Depending on the type of the created interface , there are 2 ways to delete it . In case the interface is not a valid interface for the blade such as 25.0 or even a fake name like "example" you can delete it using "no interfaces interface 25.0" If the interface is for a real interface, for example you have created interface 1/1.1 while the portgroup is in 100G mode (only 1.0 is valid) you will need the following procedure to delete it : From from the Controller running the Active Partition Login to controller that is the active one for the needed partition (can be seen via "show partitions" command on the controller). Also from "show partitions" on the controller check the partition ID. From controller bash: docker exec -it partition2_manager bash (assuming the partition ID is 2) From inside the partition run the following: confd_cmd -c "mdel /interfaces/interface{1/1.1}"
With this fix, F5OS will reject the creation of ethernetCsmacd.
