ctron-smarttrunk-mib.mib object
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2025 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2025 can import MIB file ctron-smarttrunk-mib and use it to monitor vendor specific OID's.
ctron-smarttrunk-mib file content
Object view of ctron-smarttrunk-mib:
Scalar Object |
ctTrunkGlobalStatus |
.1.3.6.1.4.1.52.4.1.2.20.1.1.1 |
The state of Smart TRUNK capability for this entire managed entity. Default Value is True(1). If set to False(2)
all smart trunks are put into ifAdminStatus down.
|
ctTrunkConfigEntry |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1 |
Each table entry contains configuration information for one trunk interface.
|
ctTrunkConnectionEntry |
.1.3.6.1.4.1.52.4.1.2.20.1.1.4.1 |
Each table entry contains configuration information
for one interface that is participating in a trunk.
|
ctTrunkLLAPRequirement |
.1.3.6.1.4.1.52.4.1.2.20.1.2.1 |
Indicates whether this managed entity requires the
LLAP updates to perform the trunking function.
Certain families of products require LLAP (decHuntGroup Protocol)
order for the Smart TRUNK functionality to work.
A value of 1 implies that LLAP is necessary for smart-trunking
to work on this platform, a value of 2 indicates that it is
not necessary.
|
ctTrunkMaxTrunks |
.1.3.6.1.4.1.52.4.1.2.20.1.2.2 |
The maximum number of trunks that can be configured
on this managed entity.
|
ctTrunkFlowDiagnosticEntry |
.1.3.6.1.4.1.52.4.1.2.20.1.2.4.1 |
Each row refers to a specific smart trunk and port within
that smart trunk.
|
Tabular Object |
ctTrunkIndex |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.1 |
A value which uniquely identifies this conceptual
row in the ctTrunkConfigTable. The Table allows sparse values.
If the conceptual row identified by this value of
ctTrunkIndex is recreated following an agent restart,
the same value of ctTrunkIndex must be used to identify
the recreated row. (However, the Interfaces table
index associated with the client may change. ifAlias in ifXTable is used
then to reassociate ifIndexes based on ifAlias. In the case of the SSR,
Smart Trunks are manipulated as st.ctTrunkIndex
|
ctTrunkConfigName |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.2 |
The Trunk's Name, just for informational purposes. It may be changed
regardless of the RowStatus value.
|
ctTrunkConfigProtocol |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.3 |
Trunking protocol in use. Once the row is active, it can not be changed.
|
ctTrunkConfigLoadBalance |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.4 |
The type of load balance algorithm applied to this trunk.
Once Row is active, the agent may override this value with an implmentation specific
default.
|
ctTrunkIfIndex |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.5 |
The ifIndex in ifTable, ifXTable that is associated with the trunk that is
represented by this row.
|
ctTrunkRowStatus |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.6 |
This object lets network managers create and delete
trunk interfaces, on systems that support this
optional capability.
It does not control the activation and deactivation
of these interfaces; they are controlled by 'ifAdminStatus'
in the ifTable. However, changing row state from active
to notInService. will have the side effect of changing
their 'ifAdminStatus' values to 'noPresent' or 'down',
thus causing any active trunk connections to be terminated.
When creating a trunk interface, it is up to the
management station to determine a suitable 'ctTrunkIndex'.
To facilitate interoperability, agents should not put
any restrictions on the 'ctTrunkIndex' beyond the obvious
ones that it be valid and unused.
The Managed Objects that must be set in this table
for a row to change from nonExistent/notReady to notInService/Active
is simply an index. Ports can then be added to the Smart TRUNK
via the ifStackTable.
If you create a trunk interface via this object,
it will initially have
'ifAdminStatus' = 'down'
'ifOperStatus' = 'down' when RowStatus is changed to active.
|
ctTrunkPortRemoteIfIndex |
.1.3.6.1.4.1.52.4.1.2.20.1.1.4.1.1 |
The ifIndex of the interface at the other end of
this part of the trunk link. If this value is 0,
then for some reason there is no interface on the
other side of this link. This might be a temporary
condition or it might represent a real problem.
Note: this table is indexed by ifIndex. So the
index is the local ifIndex value and
ctTrunkPortRemoteIfIndex is the remote ifIndex.
|
ctTrunkFlowDiagnosticInstalledFlows |
.1.3.6.1.4.1.52.4.1.2.20.1.2.4.1.1 |
A counter of the flows installed on this port since it was
first operational.
|
Table |
ctTrunkConfigTable |
.1.3.6.1.4.1.52.4.1.2.20.1.1.3 |
A table describing all of the trunk interfaces
implemented by this host. Each trunk has a row
in the MIB-II/RFC 2233 Interfaces table (describing
the structure of the trunk interface it presents to higher
layers). Each trunk interface also has a row in this and
other CTRON-SMARTTRUNK-MIB tables. Smart Trunks use
ifType propMultiplexor(54). Counters represent the aggregate of
all physcal links.
Unlike hardware ports, trunk interfaces can be created by
management. However, the RFC 2233 Interfaces table
does not directly support row creation. Therefore,
creating or deleting a row in the ctTrunkConfigTable is
defined to have the side effect of creating or
deleting corresponding rows in
- the MIB-II / RFC 2233 Interfaces table,
- any other dependent tables
New Interfaces table rows for trunk intefaces
always have 'ifAdminStatus' set to 'down' until the row
state is becomes Active. Then administration of the
interface uses normal ifTable ifAdminStatus to enabled it.
|
ctTrunkConnectionTable |
.1.3.6.1.4.1.52.4.1.2.20.1.1.4 |
This table describes how local interfaces that are
participating in a trunk are connected to remote
interfaces.
With this table, a management entity can determine
that (for example) local interfaces 3, 4, and 6 are
connected to remote interfaces 10, 17, and 19.
This table is useful to debug configuration errors
with remote devices. If ifAdminStatus/ifOperState is
up, and no corresponding row is found in this table,
then a management station can assume a the remote
end does not have the decHuntGroup protocol active.
Note: this entire table is read-only. Rows are
created and deleted from this table as a side
effect of trunks being created and deleted.
Note: a managment entity could determine (for
example) that interface 3 was participating in
trunk 3 by using the ifStackTable and ctTrunkIfIndex.
|
ctTrunkFlowDiagnosticTable |
.1.3.6.1.4.1.52.4.1.2.20.1.2.4 |
Provide a means to programmatically evaluate the load
balancing of a smart trunk. Assumes that load balancing is done on a
flow by flow basis.
