Created L1-Network cannot be deleted.
Central Manager is unable to delete the L1 Network objects on the BIG-IP Next instance.
-- BIG-IP Next instance managed and onboarded by Central Manager -- Configure network & proxy settings are already configured on the instance -- Clean up the instance's network configuration (L1 networks, Vlans, & IPs)
Workaround: 1. Delete the L1-Network in instance using CM proxy API (see below). 2. Delete the L1-Network in CM (using the UI). How to Delete the L1-Network in instance using CM proxy API: 1. Login to CM using CM login API 2. Grab the instance ID that L1-network object needs to be modified using the GET /api/v1/spaces/default/instances API. 3. Get the L1-Network ID that needs to be deleted by requesting a GET request to "api/device/v1/proxy/{INSTANCE_ID}?path=/L1-networks" 4. Delete the L1-Network by requesting a DELETE request to "/api/device/v1/proxy/{INSTANCE_ID}?path=/L1-networks/{L1_NETWORK_ID}". Take a note of the Job ID returned in the "id" param of the response. 5. Ensure that the L1-Network deletion is successful by requesting a GET request to "/api/device/v1/proxy/{INSTANCE_ID}?path=/jobs/{JOB_ID}", and ensure that the "title" under the "message" has a value of "jobUpdateSuccessful".
