tLagConfigTableConfiguration information about each Link Aggregation Group. SEQUENCE OF TLagConfigEntry .1.3.6.1.4.1.6527.3.1.2.15.2 |
tLagConfigEntryAn entry (conceptual row) in the tLagConfigTable.
Each entry represents a Link Aggregation Group.
Create or destroy rows to add or remove Link Aggregation Groups (LAG).
After tLagRowStatus is set to active(1), a corresponding
entry is created in IEEE8023-LAG-MIB dot3adAggTable.
The corresponding entry in IEEE8023-LAG-MIB dot3adAggTable is
removed when tLagRowStatus is set to destroy(6).
Use ifAdminStatus to set interface up and down for this LAG entry.
Use ifAlias for the interface description. TLagConfigEntry .1.3.6.1.4.1.6527.3.1.2.15.2.1 |

tLagPortThresholdtLagPortThreshold is a threshold for tLagPortThresholdAction.
When a physical port link state changes and the number of
operational physical ports is less than or equal to
tLagPortThreshold, tLagPortThresholdAction is invoked:
either the LAG is set operationally down, or
the protocols operating on the LAG interface are adjusted.
When the number of operational physical ports becomes greater
than tLagPortThreshold, tLagPortThresholdAction is revoked:
either the LAG is set operationally up, or the protocols
operating on the LAG interface are adjusted.
The value zero means tLagPortThresholdAction is never invoked.
To invoke dynamicCost at every physical port state change,
set tLagPortThreshold to the total number of physical ports
configured to be in the Link Aggregation Group.rw INTEGER .1.3.6.1.4.1.6527.3.1.2.15.2.1.3 |
tLagPortThresholdActionPort Threshold Action is action to take when the number of
operational (link up) physical ports is less than tLagPortThreshold.
When a physical port ifOperStatus changes and the number of
operational physical ports is less than or equal to tLagPortThreshold:
- when set to down(1), the ifOperStatus for the Link Aggregation Group
(tLagIfIndex) goes to down(2).
- when set to dynamicCost(2), the ifOperStatus stays up(2), but
dependent protocols such as OSPF are signaled and will adjust their
operation (cost) to match the number of physical ports remaining
in the Link Aggregation Group. a tLagDynamicCostOn notification
is generated.
When a physical port ifOperStatus changes and the number of
operational physical ports is greater than tLagPortThreshold:
- when set to down(1), the ifOperStatus for the Link Aggregation Group
(tLagIfIndex) goes to up(1).
- when set to dynamicCost(2), the ifOperStatus stays up(2), but
dependent protocols such as OSPF are signaled and will adjust their
operation (cost) to be the value as configured. a tLagDynamicCostOff
notification is generated.
Regardless of the setting of this object, when the number of
operational physical ports goes to zero, the Link Aggregation Group's
ifOperStatus goes to down.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.4 |
tLagEnableMarkerGeneratorenables (true(1)) or disables (false(2)) the Marker Generator
protocol.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.5 |
tLagEnableLACPenables (true(1)) or disables (false(2)) the Link Aggregation Control
Protocol (LACP).
The value of tLagEnableLACP can only be set to 'true(1)'
when tLagStandbySignaling is set to 'lacp(1)' and
the value of tLagLACPSelCrit is not 'bestPort(3)'.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.6 |
tLagDescriptiondiscription text for the Link Aggregation Group port.rw TItemLongDescription (TIMETRA-TC-MIB) .1.3.6.1.4.1.6527.3.1.2.15.2.1.7 |
tLagDynamicCostingWhen dynamic cost and OSPF autocost are both configured then costing
is applied based on the total number of links configured and the cost
is advertised inversely proportional to the number of links
available at the time, providing the number of links that are up
exceeds the configured LAG threshold value at which time the
configured threshold action determines if and at what cost this
LAG will be advertised.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.8 |
tLagLACPModetLagLACPMode represents the mode in which LACP will operate.
If the value is set to 'passive', LACP places all member ports of a
lag into a passive negotiating state. When this is the case member
ports of the lag respond to LACP packets they receive but do not
initiate LACP packet negotiation.
If the value is set to 'active', LACP places all member ports of a lag
in to an active negotiation state. When this occurs the port will
initiate LACP negotiation immediately once the port achieves link up
state. At least one of the peer lag ports must be configured as
active to initiate LACP.
The default mode is passive.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.9 |
tLagLACPAdminKeyAutogentLagLACPAdminKeyAutogen is set to 'true' if the lag administrative key
in the dot3adAggActorAdminKey object was auto generated.
tLagLACPAdminKeyAutogen is set to 'false', if the lag administrative
key was manually configured.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.10 |
tLagLACPTransmitIntervaltLagLACPTransmitInterval configures the timer interval for
periodic transmission of LACP packets. If set to 'slow', LACP packets
are transmitted every 30 seconds. If set to 'fast', LACP packets
are transmitted every second.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.11 |
tLagAccessAdaptQosThe value of tLagAccessAdaptQos specifies how the LAG SAP queue and
virtual scheduler buffering and rate parameters are adapted over
multiple active MDAs.
link (1) - The LAG will create the SAP queues and virtual
schedulers with the actual parameters on each MDA.
distribute (2) - Each MDA will receive a fraction of the SAP and
scheduler parameters.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.12 |
tLagLACPXmitStdbyThe value of tLagLACPXmitStdby specifies whether or not LACP messages
are transmitted on standby-links.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.13 |
tLagLACPSelCritThe value of tLagLACPSelCrit specifies which selection criteria
should be used to select the active sub-group.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.14 |
tLagLACPSelCritSlaveToPartnerThe value of tLagLACPSelCritSlaveToPartner specifies together with
tLagLACPSelCrit selection criteria should be used to select the
active sub-group.
The term 'eligible member' refers to a lag-member link which can
potentially become active. This means it is oper up, and not disabled
for use by the remote side. The object tLagLACPSelCritSlaveToPartner
can be used to control whether ornot this latter condition is taken
into account.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.15 |
tLagLACPNbrOfSubGroupsThe value of tLagLACPNbrOfSubGroups indicates the number of subgroups
configured in this LAG.ro Unsigned32 .1.3.6.1.4.1.6527.3.1.2.15.2.1.16 |
tLagholdTimeDownThe value of tLagholdTimeDown specifies the timer in 0.1 second
units which controls the delay between detecting that a LAG is down
(all active ports are down) and reporting it to the higher levels.
The default value for this timer is 0, i.e. the higher levels are
informed directly.
A non zero value may be configured e.g. when active/standby
signalling is used in a 1:1 fashion to avoid that the higher levels
are informed during the small time interval between detecting that
the LAG is down and the time needed to activate the standby system.rw Unsigned32 .1.3.6.1.4.1.6527.3.1.2.15.2.1.17 |
tLagPortTypeThe value of tLagPortType specifies the type of ports allowed in
this LAG.
A value of 'standard (1)' allows all non-HSMDA type ports to be added
to this LAG. A value of 'hsmda (2)' limits the LAG members to be
HSMDA-v1 ports only. A value of 'hsmdaV2 (3)' limits the LAG members
to be HSMDA-v2.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.18 |
tLagPerFpIngQueuingThe value of tLagPerFpIngQueuing specifies whether a more efficient
method of queue allocation for LAG SAPs should be utilized.
An 'inconsistentValue' error is returned if this object is set to
a different value when there are existing port members in the LAG.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.19 |
tLagSystemIdThe value of the object tLagSystemId specifies A 6-octet MAC address
used as a unique identifier for the System that contains this
Aggregator.
If set to zero, the dot3adAggActorSystemID will be used as
identifier.rw MacAddress (SNMPv2-TC) .1.3.6.1.4.1.6527.3.1.2.15.2.1.20 |
tLagSystemPriorityThe value of the object tLagSystemPriority specifies
a 2-octet value indicating the priority
value associated with the Actor's System ID.
If set to -1, the priority is taken from the object
dot3adAggActorSystemPriorityrw INTEGER (-1|0..65535) .1.3.6.1.4.1.6527.3.1.2.15.2.1.21 |
tLagStandbySignalingThe value of tLagStandbySignaling specifies
how the state of a member port is signalled to the remote side
when the tLagPortActiveStdby corresponding to this member port
has the value 'standby'.
lacp (1) - The state of this member port is signalled
to the other side through the LACP protocol.
powerOff (2) - This member port is powered off.
The value of tLagStandbySignaling can only be set to 'powerOff(2)'
when tLagEnableLACP is set to 'false(2)' and tLagLACPSelCrit is set
to 'bestPort(3)'.rw Enumeration .1.3.6.1.4.1.6527.3.1.2.15.2.1.22 |

tLagLACPPrimaryPorttLagLACPPrimaryPort contains the primary port of the LACP.
The following two conditions have to be met for the port
to become eligible for becoming the primary port:
a) Port has to be in either link up or oper up.
b) The port must have received at least one LACP PDU.
Once the above two conditions have been met, port with a highest
priority is chosen as the primary port.
