| DRA status | This field is used to configure the status of DHCP relay agent | 
| 
 | per instance. It can be disabled or configured as client port or | 
| 
 | server port. If it is configured as client port then it adds option | 
| 
 | 82 and /or do learning as per configuration. If it is configured as | 
| 
 | server port then it removes option 82 and does learning if we | 
| 
 | dont get portid from agent circuit id. | 
| 
 | 
 | 
| Option82 | This specifies the action to be performed on Option 82 on | 
| 
 | receiving DHCP discovery packets for this instance. If disabled | 
| 
 | DRA will not add Option82 tag to the DHCP packets. If | 
| 
 | AddAlways is set then Option 82 is always added. If | 
| 
 | AddIfNotExists is set then Option 82 is added only if the | 
| 
 | received DHCP packet does not contain Option 82. | 
| 
 | 
 | 
| Config  | This bitmask is used to indicate which all parameters are | 
| 
 | configured for this instance. Parameter bit set in this bitmask | 
| 
 | will overwrite the automatically derived values of agent circuit | 
| 
 | Id and/or port id by the values configured in this MO. | 
| 
 | 
 | 
| Agent Circuit Id | This is use to configure agent circuit id for this instance. If ACI | 
| 
 | bit is set in gsvDRAConfigSubOptionthen this parameter will | 
| 
 | overwrite the generated Agent Circuit Id | 
| 
 | 
 | 
| Remote Agent Id | This is use to configure remote agent id for this instance. This | 
| 
 | parameter uniquely identifies the subscriber on the associated | 
| 
 | access loop logical port on the Columbia. | 
| 
 | 
 | 
| SyncRateInfoField | This bitmask is used to indicate what all access loop | 
| 
 | characteristic parameters are to be added to access loop | 
| 
 | characteristic suboption. | 
| 
 | 
 | 
| DRA Act For Op82 | This specifies the action to be taken on receiving DHCP | 
| From Client | message from the client with option 82. If DHCP message | 
| 
 | contains option82 and we want the packet to be dropped then | 
| 
 | drop should be set and if we want the packet to be forwarded | 
| 
 | then forward should be set. | 
| 
 | 
 | 
| DRA learning | This field specifies whether DHCP learning is to be done on | 
| 
 | this port or not. If enabled DRA will learn the IP Addresses | 
| 
 | assigned towards this port using upstream/downstream | 
| 
 | packets received on this port. | 
| 
 | 
 | 
| Port No | This field specifies Atm Port number.Its value is considered | 
| 
 | only when the bitmask for portid is set in | 
| 
 | ConfigSubOptionBitmask |
