Hi,

I can set the ContextId on a GetMessage:

GetMessage request = new GetMessage();
   request.Version = SnmpVersion.Three;
   request.Security.User = agentEntity.User;
   request.Security.ContextId = System.Text.Encoding.ASCII.GetBytes(DEVICE_ID);
   ResponseMessage response = snmpSocket.GetResponse(request, agentEntity.EndPoint);

The User is sent as a parameter to GetTable but how can I set the ContextId?

Variable[,] table = snmpSocket.GetTable(tableNode.Oid, agentEntity.Version, agentEntity.Community, agentEntity.User, agentEntity.EndPoint, 3, 100);

Best Regards,
Anders Havn

Hello Anders,

It is not currently possible to set the ContextId when using the GetTable method, I have entered a feature request for this as TFS390. For information and updates on its status, please contact sales@dart.com. In the meantime, GetNextMessage or GetBulkMessage may be used to retrieve the table values.

Hello, we have the same issue of needing ContextId when getting a table.

This has been five years, please can you tell me when this functionality is to be available?

We shouldn't be downgrading functionality when people move to a more secure platform.


Thanks,


Dave

Thank you for your post. This issue was resolved and a resolution released several years ago. If you'd like to know whether the version you have includes this functionality, please email sales@dart.com.

Jamie
