MIBs Provided with TCP/IP Services
2.1 Overview of the Host Resources MIB
TCPIP$SNMP_REQUEST.EXE responds with no output and returns directly
to the DCL prompt.
After an NFS mount, the following information is returned in response to a
Get
request. The data items implemented for OpenVMS (refer to RFC 1514)
are:
–
hrFSIndex
.
–
hrFSMountPoint
is the local DNFS device name.
–
hrFSRemoteMountPoint
is the remote file system.
–
hrFSType
is implemented as:
•
OID 1.3.6.1.2.1.25.3.9.1, for OpenVMS if the file system is not a UNIX
style container file system.
•
hrFSNFS
, OID 1.3.6.1.2.1.25.3.9.14, if the file system is a TCP/IP
Services container file system or a UNIX host.
–
hrFSAccess
, as defined in RFC 1514.
–
hrFSBootable
is always HRM_FALSE (integer 2).
–
hrFSStorageIndex
is always 0.
–
hrFSLastFullBackupDate
is unknown time. This entry is encoded
according to RFC 1514 as a hexadecimal value 00-00-01-01-00-00-00-00
(January 1, 0000).
–
hrFSLastPartialBackupDate
is unknown time. This information is not
available for OpenVMS systems. Instead, hexadecimal value 00-00-01-01-
00-00-00-00 (January 1, 0000) applies.
•
hrProcessorFrwID
(OID prefix 1.3.6.1.2.1.25.3.3.1.1) is not implemented on
OpenVMS VAX. On this type of system, it returns standard null OID (0.0).
For example:
1.3.6.1.2.1.25.3.3.1.1.1 = 0.0
For OpenVMS Alpha (firmware version 5.56-7), the response is shown in the
following example:
1.3.6.1.2.1.25.3.3.1.1.1 = 1.3.6.1.2.1.25.3.3.1.1.1.5.56.7
•
Data items in the
hrDiskStorage
table have the following restrictions:
–
hrDiskStorageMedia
is always ‘‘unknown’’ (2).
–
hrDiskStorageRemoveble
is always ‘‘false’’ (2). Note the incorrect spelling
of ‘‘removable’’ in
hrDiskStorageRemoveble
(from RFC 1514).
•
hrStorageType
always contains the value of
hrStorageFixedDisk
(1.3.6.1.2.1.25.2.1.4).
2.2 Overview of MIB II
The Standard MIB (MIB II) described in RFC 1213 defines a set of objects useful
for managing TCP/IP Internet entities. MIB II supports network monitoring
and managing from the Transport layer down to the Physical layer of the
TCP/IP internet stack. This MIB also provides information on how connections
are established and how packets are routed through the Internet. For more
information about MIB architecture, see Section 3.2.
