This object denotes the default maximum number
of unacknowledged I PDUs that LLCs on this SAP
can expect to receive from their remote LLC
partners. This count is referred to as 'k' in
the IEEE 802.2 specification [5].
A zero value for this object indicates that the
port default, llcPortAdminMaxUnackedIPDUsRcv,
shall be used as the SAP default. This SAP
default value may be overridden by a non-zero
value in the llcCcAdminMaxUnackedIPDUsRcv
object.
At connection setup, an implementation may
choose to send this value to the remote LLC,
using an XID frame.
