posted January 26, 2018 10:03 AM Hello, I created a child table in the parent table. Parent table have 34 tablecolumn and 35th is child table. When i import my mib file the solution, dart creates csharp code. Both mib and csharp code snippets are below. I also tried by using "AUGMENTS" keyword. So i want to access by parent index and child index. For example 1.3.6.1.3.480.1.35.[ParentIndex].1.[ChildIndex] How can do this? It is also discussed in the following links: https://stackoverflow.com/questions/30598525/snmp-nested-table-defined-one-level-below-the-parent-table https://stackoverflow.com/questions/2510211/snmp-asn-1-mib-definitions-referencing-a-table-within-a-table/2510340#2510340 MIB Snippet: arentTable OBJECT-TYPE SYNTAX SEQUENCE OF parentEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Parent table" ::= { example 480 } parentEntry OBJECT-TYPE SYNTAX ParentEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Entry in Parent table" INDEX { parentIndex } ::= { parentTable 1 } ParentEntry ::= SEQUENCE { parentIndex Unsigned32, -- other columns in the table } childTable OBJECT-TYPE SYNTAX SEQUENCE OF childEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Child table" ::= { example 480 } childEntry OBJECT-TYPE SYNTAX ChildEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Entry in Child table" INDEX { parentIndex, childIndex } ::= { childTable 1 } ChildEntry ::= SEQUENCE { childIndex Unsigned32, -- other columns in the table } |

posted January 26, 2018 11:46 AM Hello, Can you clarify what you're looking for by asking "How can do this?"? Fundamentally, it's just by specifying the relevant numerical indexes in place of those ParentIndex and ChildIndex "variables". |

posted January 29, 2018 10:02 AM Hello, I'm sorry because last week my question is so confusing. As I clarify below: I have multiple identical device as 'myDevice' and each device has 128 channels. I have written MIB that channelTable references myDeviceTable. So i want to access childTable with parent index, but when i import the MIB file via PowerSnmp to my agent, I cannot access. I can send my solution if necessary. |
