a question aboat: Mibs structure

[Mostafa Salari]

Hello
When I execute [snmpwalk -c public -v1 localhost -On] in my Ubuntu shell
(on vm ware) I see an OID such as:
.1.3.6.1.2.1.28.0 which has a Counter32 value and is translated
to: SNMPv2-MIB::snmpOutGetResponses.0

here: { http://www.oid-info.com/cgi-bin/ } wa can search an OID and view
the description.
So, I can search 1.3.6.1.2.1.28 and view the result, but 1.3.6.1.2.1.28.0
gets no result.
I want to ask you: What is the meaning of ".0" at the tail of the OID?

An 'instance' of an OID is referenced by its base OID and the index of the
specific instance.
so the .0 is the index part. Indexes may be complex, when refereing to
instances inside
rows of a table; or in this case a .0 is (and implies) a single scalar
variable.
