When a VLAN is created using a reserved name and assigned to a tenant, MCPd fails to load the configuration. The following errors are observed: - 01070088:3: The requested object name (/Common/mgmt) is invalid - 01070712:3: Internal error, object is not in a folder: type: vlan id: /Common/mgmt - Cannot set MAC address for to '<mac_address>' in rd0 - ioctl failed: No such device
MCPd is unable to load the configuration or list VLANs, potentially causing tenant network connectivity issues and preventing VLAN management operations.
- F5OS environment with tenant configuration - VLAN created with a reserved system name such as mgmt, eth0, tmm, or tmm_bp - VLAN assigned to a tenant
Avoid using reserved names (mgmt, eth0, tmm, tmm_bp, etc.) when creating VLANs in F5OS. Use alternative, non-reserved naming conventions for VLAN objects.
