The imaLinkRowStatus object allows create, change and delete operations on imaLinkTable entries. To create a new conceptual row (or instance) of the imaLinkTable, imaLinkRowStatus must be set to 'createAndWait' or 'createAndGo.' A successful set of the object imaLinkGroupIndex must be performed before the RowStatus of this new row can transition to the 'Active' state. The imaLinkGroupIndex provides the association between a physical IMA link to an IMA group. To change (modify) an imaLinkTable entry, the imaLinkRowStatus object must be set to 'notInService'. Only then can the conceptual row be changed. Setting object imaLinkGroupIndex to a different value has the effect of changing the association between a physical IMA link and an IMA group. To place the link 'in group', the imaLinkRowStatus object is set to 'Active'. While the row is not in 'Active' state, both the Transmit and Receive IMA state machines are in the 'Not In Group' state. To remove (delete) an imaLinkTable entry from this table, set this object to 'destroy.' A network manager may elect to perform a delete operation followed immediately by a create operation instead of a modify operation. The net effect of the delete/create is to re-instantiate (reset) agent counters defined in this table.
