Bug ID 1623017: Interface VLAN in Use While Top-Level VLANs/VLAN Deleted

Last Modified: Jul 15, 2026

Affected Product(s):
F5OS F5OS-C(all modules)

Known Affected Versions:
F5OS-A 1.7.0

Fixed In:
F5OS v2.0.0

Opened: Aug 02, 2024

Severity: 3-Major

Symptoms

A VLAN component can be deleted from the configuration while it is configured under the interface.

Impact

There is no impact on functionality. The OpenConfig interface VLAN is modeled as a standalone leaf, rather than a leaf reference to the VLANs/vlan component. The interface VLAN continues to function as expected, even if the top-level VLANs/vlan is deleted.

Conditions

When a VLAN component is configured to be used by an interface, and the user deletes the VLANs/VLAN.

Workaround

Do not remove the VLANs/VLAN if in use by an interface.

Fix Information

Business logic was added to prevent users from deleting the VLANs/VLAN components while in use by an interface.
