| stackConfiguration | 1.3.6.1.4.1.43.10.27.1 | | | |
| stackConfigTable | 1.3.6.1.4.1.43.10.27.1.1 | | not-accessible | |
| stackConfigEntry | 1.3.6.1.4.1.43.10.27.1.1.1 | | not-accessible | |
| INT stackUnitLocation | 1.3.6.1.4.1.43.10.27.1.1.1.1 | INTEGER | not-accessible | Used to identify individual units in the stack. Note that
this value will usually be contiguous, but that gaps may be present due,
for example, to unpowered units. |
| PHY stackUnitAddress | 1.3.6.1.4.1.43.10.27.1.1.1.2 | PhysAddress | read-only | Every conformant unit in the SuperStack II system will have
a unique physical (MAC) address by which it can be recognised. Note
that the location index on this table can change if a unit is inserted
into the stack and so the location can not be used to uniquely identify
a location. Instead an application should refer to units by their
physical address. |
| TIK stackUnitLastReset | 1.3.6.1.4.1.43.10.27.1.1.1.3 | TimeTicks | read-only | This is the time in hundredths of a second, since this unit
last reset (ie that units concept of sysUpTime). Note that if a unit is
not operational then this object will report zero (0). |
| INT stackUnitType | 1.3.6.1.4.1.43.10.27.1.1.1.4 | INTEGER | read-only | This is an integer type identifier for this unit. The values
of this integer are administered by allocating a MIB object identifier
for each type of unit from a common branch. The value of this object is
then the last level in that identifier. The values are defined in this
MIB module. Note that the values are unlikely to be contiguous.
Note that if a type value is not available for this unit then this
object will return zero. There are several reasons why this value may
not be available through this view of the MIB. One reason may be that
the device is not currently active (dead) or that the information is
only available through the units own agent (see stackUnitManagementType)
. |
| STR stackUnitDesc | 1.3.6.1.4.1.43.10.27.1.1.1.5 | DisplayString | read-only | This is a text string which describes this unit. If a unit
cannot provide a name then the value of this object will be an empty
string. |
| STR stackUnitName | 1.3.6.1.4.1.43.10.27.1.1.1.6 | DisplayString | read-write | This is a simple text string which can be used by an
application to assign a text name to a unit. By default this string is
empty. If a management application writes a text string to this object
the device will store the string in non-volatile storage. |
| INT stackUnitState | 1.3.6.1.4.1.43.10.27.1.1.1.7 | INTEGER | read-only | This object represents the best known state of a unit in the
stack. The unknown state is not expected to be used, but may exist
because of loosely integrated components in the stack. Management
applications MUST EXPECT to see the 'unknown' value. The other states
are as follows:
unitInactive: The device has failed to respond send out periodic update
messages, but it still appears to be in the stack.
unitOperational: The unit is sending our periodic identification
messages and indicates that it is operational, running its complete
image.
unitLoading: The unit is running is a special operational mode which
means that it is unmanaged while it loads a new operational code image.
Note that if the stack ever contains units which can download an
operational image while still being fully managed then this variable
will report 'unitOperational'. |
| INT stackUnitManagementType | 1.3.6.1.4.1.43.10.27.1.1.1.8 | INTEGER | read-only | This object can be used to determine the management method
used to access the agent in this unit. The options are:
unknown: The unit has not reported any management capability. It
is either faulty or a non-conformant device.
distributed: This unit can be managed using the SuperStackII
distributed management architecture and so is managed
through this agent. The unit may or may not have an
active comms stack. If it has then the addresses for
that agent can be determined from the address table.
intelligent: The unit has its own SNMP agent which is accessed
seperately. The agent is not part of the SSII
distributed management architecture. |
| OCT stackUnitCapabilities | 1.3.6.1.4.1.43.10.27.1.1.1.9 | OCTET STRING | read-only | This object describes the capabilities of this particular
unit. This is used in conjunction with the upgrade level of the stack
to enable a management application to correctly enable and disable the
various features of the application depending on the capabilities of
the unit.
The object is an octet string, where each octet represents a capability
of the unit. Different capabilities will be added to the list as
required. The current list of values is:
0x01 Full RMON
0x02 3Com Proprietary Resilience MIB
0x03 3Com Repeater Security MIB
0x04 PSHub Port Switching
0x05 PSHub Capability Upgrade Facility
0x06 Dual Speed Hub Capability Upgrade Facility
0x07 TelNet
0x08 Web
0x14 SMA Resource Allocator
0x15 SMA Distributed SNMP
0x16 SMA Global Variables
0x17 SMA Licence Server
0x18 PSHub Cascade Switch
0x19 PSH Load Balancing
So, for example, if a unit has a value of '02 03' for this object then
it supports repeater resilience and security, but no other features
such as RMON. |
| STR stackUnitPromVersion | 1.3.6.1.4.1.43.10.27.1.1.1.10 | DisplayString | read-only | This is the version number of the PROM on the unit. If the
unit has no PROM, does not correctly report the PROM version or is
currently non-operational then this object will return an empty string. |
| STR stackUnitHWVersion | 1.3.6.1.4.1.43.10.27.1.1.1.11 | DisplayString | read-only | This is the hardware version of this unit, expressed as a
string. Note that if the hardware version is not available for this
particular unit then the version string will be empty. |
| STR stackUnitSWVersion | 1.3.6.1.4.1.43.10.27.1.1.1.12 | DisplayString | read-only | This is the software version number of this unit. The
software version number is a string. Note that if a unit does not make
its version number information available, or the unit has no software,
then this object will report an empty string. |
| STR stackUnitSerialNumber | 1.3.6.1.4.1.43.10.27.1.1.1.13 | DisplayString | read-only | This is the serial number for this unit. The number is
globally unique and expressed as a textual string. |
| INT stackUnitAttention | 1.3.6.1.4.1.43.10.27.1.1.1.14 | INTEGER | read-write | Some of the units in the stack will contain a mechanism for
drawing attention to that unit. This is useful for directing
maintainance personnel. The method often employed is for a special LED,
or by placing some other LED into a flashing state. This object gives
access to the attention mechanism for a unit.
Note that if a unit does not support this mechanism then reading the
value of this object will return 'no-such-name' error. The possible
values for an instance of this object which does exist is 'noAttention'
or 'attention'. |
| INT stackUnitMgmtInterface | 1.3.6.1.4.1.43.10.27.1.1.1.15 | INTEGER | read-only | If a unit in the stack participates in the distributed
SNMP stack then it will have an instance of this object
(stackUnitManagementType = 'distributed'). The object points to the
entry in the interface table which represents the potential management
interface for this unit. That is the index to use in the extIfTable for
this device. Note that if the value of this object is zero, or the
result of reading this object is NO-SUCH-NAME then there is no
management interface available on that unit. |
| OCT stackUnitSummary | 1.3.6.1.4.1.43.10.27.1.1.1.16 | OCTET STRING | read-only | This object provides a summary of this units configuration
in order to improve the performance of the management applications. The
information in this object is represented as a list of items, each item
is a type-length-value triplet which will have a basic encoding. The
information encoded in this string will be determined by the
requirements of the management applications. It is expected that the
following information will be compressed into this object for a
repeater device:
Unit type Number of ports Array of port information including:
media type, link state, partition state. |
| INT stackUnitSlipMgmtInterface | 1.3.6.1.4.1.43.10.27.1.1.1.17 | INTEGER | read-only | If a unit in the stack participates in the distributed
SNMP stack then it will have an instance of this object
(stackUnitManagementType = 'distributed'). The object points to the
entry in the interface table which represents the potential SLIP (serial
port) management interface for this unit. That is the index to use in
the extIfTable for this device. Note that if the value of this object
is zero, or the result of reading this object is NO-SUCH-NAME then
there is no SLIP access port available on that unit. |
| stackAddressInformation | 1.3.6.1.4.1.43.10.27.2 | | | |
| stackAddressTable | 1.3.6.1.4.1.43.10.27.2.1 | | not-accessible | This table contains entries for units in the stack which
have active inband communications stacks. The table comprises of a set
of entries for each unit, each entry representing a single address.
Note that the address information in this table cannot be changed!
This table is required specifically for those units which execute their
own SNMP agents without taking part in the Arnie co-operative agent. Ie,
the only devices for which there will be an entry in this table are
those for which the stackUnitManagementType is 'Intelligent'. |
| stackAddressEntry | 1.3.6.1.4.1.43.10.27.2.1.1 | | not-accessible | |
| INT stackAddressNumber | 1.3.6.1.4.1.43.10.27.2.1.1.1 | INTEGER | read-only | This identifies one of a number of different addresses for
this unit. This is a second index column for this table, the first
being the unit number shared with the stackConfigTable (stackUnitLocatio
n). |
| INT stackAddressType | 1.3.6.1.4.1.43.10.27.2.1.1.2 | INTEGER | read-write | |
| OCT stackAddress | 1.3.6.1.4.1.43.10.27.2.1.1.3 | OCTET STRING | read-write | The address. |
| stackSysObjIdentities | 1.3.6.1.4.1.43.10.27.4 | | | |
