This object denotes the default value for the
maximum number of times that LLCs on this SAP
shall retry PDUs following the expiration of
the acknowledgement timer, the P-bit timer or
the reject timer. When these retries are
exhausted, the link shall be declared inactive.
This count is referred to as 'N2' in the IEEE
802.2 specification [5].
A zero value for this object indicates that the
port default, llcPortAdminMaxRetransmits, shall
be used as the SAP default. This SAP default
value may be overridden by a non-zero value in
the llcCcAdminMaxRetransmits.
