| Description | The imaGroupRowStatus object allows create, change, and delete
operations on imaGroupTable entries.
To create a new conceptual row (or instance) of the imaGroupTable,
imaGroupRowStatus must be set to 'createAndWait' or 'createAndGo'.
If settable, a successful set of the following objects must be
performed before the imaGroupRowStatus of a new conceptual row can
be set to 'active':
imaGroupMinNumTxLinks
imaGroupMinNumRxLinks
imaGroupTxImaId
Some objects in the imaGroupTable control settings which can only
be established or changed at group start-up time. These objects
include:
imaGroupTxImaId
imaGroupSymmetry
imaGroupTxFrameLength
To change (modify) the imaGroupTxImaId object, the manager must
first set imaGroupRowStatus to 'notInService'. However, changes
to the following two objects can be optionally allowed while the
imaGroupRowStatus is 'active':
imaGroupSymmetry
imaGroupTxFrameLength
These two objects can be changed when the imaGroupRowStatus is
'active' in order to allow the far-end to recover from its
Config-Aborted state without having to force the near-end Group
State machine to go to the 'Not Configured' state. Changing
these object values after group start-up has completed causes a
restart of the IMA group.
Alternatively, as noted above, the agent implementation may
simply require the imaGroupRowStatus object to first be set to
'notInService' before allowing changes to either of these two
objects.
To remove (delete) an imaGroupTable entry from this table, set
imaGroupRowStatus to 'destroy'.
Setting the imaGroupRowStatus to 'active' has the effect of
activating the Group Startup Procedure. The Group Startup
Procedure uses provisioned links that have imaLinkRowStatus set
to 'active' and imaLinkGroupIndex set to the imaGroupIndex in
this conceptual row.
When the imaGroupRowStatus is not in 'active' state, the Group
State machine is in its 'Not Configured' state. |
