by I am using MG-SOFT MIB Browser (Professional Edition 6.10.0.3633).
Here are properties of three nodes (via the Browser):
1) <prefix>.mib-2.system // non-terminal node
2) <prefix>.mib-2.system.sysObjectID // terminal node
3) <prefix>.mib-2.system.sysContact // terminal node
############## PROPERTIES : BEGIN #############
=== Properties : 'system' =====================
Name: system
Type: OBJECT-IDENTIFIER
OID: 1.3.6.1.2.1.1
Full path: iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2
(1).system(1)
Module: RFC1213-MIB
Parent: mib-2
First child: sysDescr
Next sibling: interfaces
=== Properties : 'sysObjectID' ================
Name: sysObjectID
Type: OBJECT-TYPE
OID: 1.3.6.1.2.1.1.2
Full path: iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2
(1).system(1).sysObjectID(2)
Module: RFC1213-MIB
Parent: system
Prev sibling: sysDescr
Next sibling: sysUpTime
Numerical syntax: Object Identifier
Base syntax: OBJECT IDENTIFIER
Composed syntax: OBJECT IDENTIFIER
Status: mandatory
Max access: read-only
Description: The vendor's authoritative identification of the
network management subsystem contained in the
entity. This value is allocated within the SMI
enterprises subtree (1.3.6.1.4.1) and provides an
easy and unambiguous means for determining `what
kind of box' is being managed. For example, if
vendor `Flintstones, Inc.' was assigned the
subtree 1.3.6.1.4.1.4242, it could assign the
identifier 1.3.6.1.4.1.4242.1.1 to its `Fred
Router'.
============ Properties : 'sysContact' ========
Name: sysContact
Type: OBJECT-TYPE
OID: 1.3.6.1.2.1.1.4
Full path: iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2
(1).system(1).sysContact(4)
Module: RFC1213-MIB
Parent: system
Prev sibling: sysUpTime
Next sibling: sysName
Numerical syntax: Octets
Base syntax: OCTET STRING
Composed syntax: DisplayString
Status: mandatory
Max access: read-write
Size list: 1: 0..255
Description: The textual identification of the contact person
for this managed node, together with information
on how to contact this person.
############## PROPERTIES : BEGIN #############
Type of 'sysObjectID' (non-terminal node) is OBJECT-TYPE
Type of 'sysContact' (non-terminal node) is OBJECT-TYPE
Type of 'system' (terminal node) is OBJECT-IDENTIFIER (not
OBJECT IDENTIFIER)
OBJECT-TYPE is construct.
However, I didn't find construct OBJECT-IDENTIFIER.
Note. It seems that OBJECT-IDENTIFIER (with hyphen)
has nothing to do with datatype OBJECT IDENTIFIER (with space)
using in syntax.
What OBJECT-IDENTIFIER is?
Is there any definition of OBJECT-IDENTIFIER : in ASN.1 ? in SNMP
documents?
Thanks in advance,
