| 
 | mgmtmode Data | It denotes the Management Mode of the ATM VC. If it is Data, then only | 
 | ||
| 
 | Mgmt DataAndMgmt | data transmission can take place. If it is Mgmt, then management of | 
 | ||
| 
 | Raw | remote CPE device can happen on that ATM VC and packets on that | 
 | ||
| 
 | 
 | ATM VC shall start coming to Control Plane. In DataAndMgmt mode, | 
 | ||
| 
 | 
 | data transmission as well as remote CPE management can happen on | 
 | ||
| 
 | 
 | the same ATM VC interface. In DataAndMgmt mode, the acceptable | 
 | ||
| 
 | 
 | values for atmVCCAAL5EncapType are llcmux and auto. In Mgmt | 
 | ||
| 
 | 
 | mode, EoA interface cannot be created on the ATM VC and both | 
 | ||
| 
 | 
 | Ethernet as well as  | 
 | ||
| 
 | 
 | received at the Control Plane. In DataAndMgmt mode, if EoA is created, | 
 | ||
| 
 | 
 | then only  | 
 | ||
| 
 | 
 | Control Plane. However, if EoA is not created then all the packets on | 
 | ||
| 
 | 
 | that ATM VC shall be received at the Control Plane. However, to | 
 | ||
| 
 | 
 | configure ATM VC in DataAndMgmt mode, a good practice is to to | 
 | ||
| 
 | 
 | create ATM VC in disable mode till EoA is created on it, to prevent | 
 | ||
| 
 | 
 | flooding at Control Plane. In order to run STP, the mode has to be | 
 | ||
| 
 | 
 | DataAndMgmt. If the mode is RawATM(4), ATM cells are given to | 
 | ||
| 
 | 
 | Control Plane. In this mode, EoA interface cannot be created on the | 
 | ||
| 
 | 
 | ATM VC. If EoA interface is already created on the ATM VC, its mode | 
 | ||
| 
 | 
 | cannot be changed to either Mgmt(2) or RawATM(4). This field is not | 
 | ||
| 
 |
