If the link type specified by cgspLinkType is 'sctpIp',
this is the association identifier defined in the
Stream Control Transmission Protocol(SCTP) MIB. Where
value greater than zero indicates a valid association.
The zero value indicates an association does not exist
for this link. This value will always be set to
zero one when cgspLinkType is not equal to the
'sctpIp' value. This object replaces
cgspLinkSctpAssociation and allows association
identifiers to be larger than 65,535.
