When "tmsh load sys config default"
NA
When the command "load sys config default" is executed, the VLAN configurations are not removed; however, the underlying trunk configurations are removed and then recreated. This operation results in a stale interface pointer (ifp) within the interface structure (ifc). Since existing VLANs are not deleted during the load system configuration process, the logic has been extended to include the associated trunks as well
