RE: Problem related to OID representation

Many thanks Dev, for your reply. 

 

Just to get the clear picture suppose the tables is having display
string and integer as data type of the indices .Suppose for
"1.2.3.4.5.6.1.1.2.abc.1"

 

I should be sending "1.2.3.4.5.6.1.1.2.97.98.99.1" or
"1.2.3.4.5.6.1.1.2.97.98.99.49" (49 is ASCII representation of 1) and
what if other index is IP address .So for
1.2.3.4.5.6.1.1.2.abc.192.168.221.10 what will be OID representation.

 

In case of index as mac address .How  OID will be represented ?

For example for 1.2.3.4.5.6.1.1.2.aa.bb.cc.dd.ee.ff what will be the OID
?

In case of IP address index what will be the OID representation .

 

 

 

If the index is not implied then for table which need two column as
index what will be the OID representation.

For example 1.2.3.4.5.6.1.1.2.abc.xyz

Will it be 1.2.3.4.5.6.1.1.2.3.97.98.99.3.120.121.122

Or it will be 1.2.3.4.5.6.1.1.2.6.97.98.99.120.121.122

You would either send

 

   1.2.3.4.5.6.1.1.2.97.98.99

or

   1.2.3.4.5.6.1.1.2.3.97.98.99

 

depending on how the table was defined in the MIB.

(in particular, whether IMPLIED was specified in the INDEX clause)

The trap manager would need to have the relevant MIB loaded.

This then tells it how to interpret the incoming OID.

You'd list each index value in turn.

Please see section 7.7 of RFC 2578, which explains how to

handle the index values of a table in some detail.
