Re: [lwip-users] Help with SNMP Table Columns vs Rows and extra node

[Trampas Stern]

I am in the same exact boat... 

I though the node would be one less from the code, and the columns and rows were swapped.  However I figured that the columns and rows are just a nomenclature thing and I really do not care when you do the snmpwalk which way they show up.  

For my application I will have around 3400 SNMP parameters, so far I have gotten 2800 working.  92 sensors with 29 parameters each is the bulk of them. 

I am also going to have enable SNMP v3, so if you get there first let me know.

Hello all,

I was testing the SNMP private example: lwip/contrib/examples/snmp/snmp_private_mib/
and I got this
iso.3.6.1.4.1.26381.1.1.1.1.1 = INTEGER: 11
iso.3.6.1.4.1.26381.1.1.1.1.2 = INTEGER: 22
iso.3.6.1.4.1.26381.1.1.1.1.3 = INTEGER: 33
iso.3.6.1.4.1.26381.1.1.1.1.4 = INTEGER: 44
iso.3.6.1.4.1.26381.1.1.1.2.1 = STRING: "0.txt"
iso.3.6.1.4.1.26381.1.1.1.2.2 = STRING: "1.txt"
iso.3.6.1.4.1.26381.1.1.1.2.3 = STRING: "2.txt"
iso.3.6.1.4.1.26381.1.1.1.2.4 = STRING: "3.txt"
iso.3.6.1.4.1.26381.1.2.0 = INTEGER:

I noticed that the source code the TABLE is created with Columns
however, it looks that from my specification (the private MIB I must implement) it is defined as Rows.
Would it be possible ?

so I will get something instead:

iso.3.6.1.4.1.26381.1.1.1.1 = INTEGER: 11
iso.3.6.1.4.1.26381.1.1.1.2 = STRING: "0.txt"
iso.3.6.1.4.1.26381.1.1.2.1 = INTEGER: 22
iso.3.6.1.4.1.26381.1.1.2.2 = STRING: "1.txt"
iso.3.6.1.4.1.26381.1.1.3.1 = INTEGER: 33
iso.3.6.1.4.1.26381.1.1.3.2 = STRING: "2.txt"
iso.3.6.1.4.1.26381.1.1.4.1 = INTEGER: 44
iso.3.6.1.4.1.26381.1.1.4.2 = STRING: "3.txt"
iso.3.6.1.4.1.26381.1.2.0 = INTEGER:


Another question, it looks Table is creating a new node in between:
iso.3.6.1.4.1.26381.1.1.1.1.1 = INTEGER: 11
iso.3.6.1.4.1.26381.1.2.0 = INTEGER:

and I was expecting it with less one node in the hierarchy:
iso.3.6.1.4.1.26381.1.1.1.1 = INTEGER: 11
iso.3.6.1.4.1.26381.1.2.0 = INTEGER:


I am also completely new to SNMP so I have no idea if it should be columns or rows or what about this extra node if it is expected.

Anyone could clarify me ?
