Gateway
rfc – Standard RFC 2960 algorithm in the retransmission delay doubles after each retransmission.
The RFC 2960 standard for congestion control is also used.
lin – Tekelec's linear retransmission policy where each retransmission timeout value is the same
as the initial transmission timeout and only the slow start algorithm is used for congestion control.
:rmin – The minimum value of the calculated retransmission timeout in milliseconds, from 10 - 1000.
:rmax – The maximum value of the calculated retransmission timeout in milliseconds, from 10 - 1000.
:rtimes – The number of times a data retransmission will occur before closing the association from
3 - 12.
:cwmin – The minimum size in bytes of the association's congestion window and the initial size in
bytes of the congestion window, from 1500 - 409600. The cwmin parameter value must be less than
or equal to the size of the buffer used by the association, shown by the bufsize parameter value. If
the buffer size for the association needs to be changed, perform
Association.
The rmode, rmin, rmax, rtimes, and cwmin parameters are used to configure the SCTP retransmission
controls for an association, in addition to other commands. Perform
Control for a M2PA Association
:istrms – The number of inbound streams (1 or 2) advertised by the SCTP layer for the association.
:ostrms – The number of outbound streams (1 or 2) advertised by the SCTP layer for the association.
:m2patset – The M2PA timer set assigned to the association. The m2patset parameter can be
specified only with the adapter=m2pa parameter, or if the association already has the adapter=m2pa
parameter assigned and the adapter parameter value is not being changed. If the adapter parameter
value is being changed to m2pa, and the m2patset parameter is not specified, the default value for
the m2patset parameter (1 - M2PA timer set 1) is assigned to the association. If the adapter parameter
value for the association is m2pa, is not being changed, and the m2patset parameter is not specified
with the chg-assoc command, the m2patset parameter value is not changed.
:ver – The M2PA version assigned to the M2PA association, either the RFC version (ver=rfc), or
the Draft 6 version (ver=d6). The ver parameter can be specified only if, when this procedure is
completed, the adapter parameter value is m2pa. If the adapter parameter value is being changed
to m2pa, and the ver parameter is not specified, the default M2PA version of RFC is assigned to the
association. To change the ver parameter value, the open parameter value for the association must
be no.
:uaps – The UA parameter set value being assigned to an M2PA or an M3UA association.
:rtxthr – The retransmission threshold for the association. The rtxthr parameter value indicates
the number of retransmissions that can occur on the association that when exceeded will generate
UAM 0537, Ethernet Error Threshold Exceeded. The value of this parameter is 0 to 65,535. The value
of this parameter is shown in the RTXTHR field of the rtrv-assoc:aname=<association name>
output. The rtxthr parameter value can be changed if the open parameter value is either yes or no.
:rhosttype – The type of remote host assigned to the association, primary or alternate. The
primary remote host is shown in the RHOST field of the rtrv-assoc:aname=<association name>
output. The alternate remote host is shown in the ARHOST field of the
rtrv-assoc:aname=<association name> output.
An alternate remote host can be configured for multi-homed associations using the rhost and
rhosttype parameters of the chg-assoc command. The rhost parameter value with the
rhostype=primary parameter represents an IP address that corresponds to one of the network
