SNMP reading OBJECT IDENTIFIER

kappa74 — Fri, 24 Oct 2014 08:19:20 GMT

Good morning,

I have a problem about SNMP OBJECT IDENTIFIER: I don't understand how reading an object identifier in SNMP.

I need to change the value of sysObjectID which is now .0.0. (this is the default).

The structure to read its value in 1213.c file is:

const RTCSMIB_VALUE MIBVALUE_sysObjectID = {

RTCSMIB_NODETYPE_OID_PTR,

NULL

};

The value is a pointer to NULL.

Do you have an example which shows how to change its value (example .1.3.6.1.2.1.1.1 SysDescr)?

Thank you

Best Regards

Mirko

I have the same problem that you. I need to set a OID VALUE another mib object, but MQX can't. I have been tried using RTCSMIB_NODETYPE_OID_FN too, but I can't know what kind of value I need to set. I believe that MQX have a bug in this case or setting a complete OID value ( ex.: .1.3.6.1.23.56) in another OID it's not implemented yet. Does anybody can check this?

Hi thiagow,

I solved in this way.

I defined the node of the my machine

const RTCSMIB_NODE MIBNODE_machine = {

NULL,

(RTCSMIB_NODE_PTR)&MIBNODE_analog_input,

(RTCSMIB_NODE_PTR)&MIBNODE_board,

NULL,

NULL, 0, NULL, NULL

};

and then in the struct of MIBVALUE_sysObjectID I inserted the pointer to the MIBNODE_machine

const RTCSMIB_VALUE MIBVALUE_sysObjectID = {

RTCSMIB_NODETYPE_OID_PTR,

(void _PTR_)(RTCSMIB_VALUE_PTR)&MIBNODE_machine

};

In this way it's working.

Best Regards
