To create a new conceptual row (or instance) of the hwImaLinkTable, hwImaLinkRowStatus must be set to 'createAndWait' or 'createAndGo'. A successful set of the imaLinkGroupIndex object must be performed before the hwImaLinkRowStatus of a new conceptual row can be set to 'active'. To change (modify) the imaLinkGroupIndex in an hwImaLinkTable entry, the hwImaLinkRowStatus object must first be set to 'notInService'. Only then can this object in the conceptual row be modified. This is due to the fact that the imaLinkGroupIndex object provides the association between a physical IMA link and the IMA group to which it belongs, and setting the imaLinkGroupIndex object 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 hwImaLinkRowStatus object is set to 'active'. While the row is not in 'active' state, both the Transmit and Receive IMA link state machines are in the 'Not In Group' state. To remove (delete) an hwImaLinkTable entry from this table, set this object to 'destroy'." ::= { hwImaLinkEntry 51 } -- Conformance Information hwImaMibGroups OBJECT IDENTIFIER ::= { hwImaMibConformance 1 } hwImaMibCompliances OBJECT IDENTIFIER ::= { hwImaMibConformance 2 } -- Compliance Statements hwImaMibCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for network elements implementing Inverse Multiplexing for ATM (IMA) interfaces."
