Define RTXTHR Parameter

:rtxthr –The retransmission threshold for the association. The RTXTHR parameter value indicates the number of packet re-transmissions that can occur on the association (per monitoring time period of 2 seconds). Alarm "IP Connection Excess Retransmits" (UAM 536) will be raised if the number of packets re-transmitted is greater than the configured RTXTHR parameter value, during 5 such consecutive monitoring periods. Once alarm is raised, it may require up to 12 consecutive monitoring periods with the number of re-transmissions < RTXTHR to clear the alarm. The design allows the alarm to come on at low error rates, and not come for occasional errors.

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". It is possible to configure the RTXTHR so that UAM 536 alarms if the error rate on association is above the recommended maximum packet loss of 0.025%. If the error rate is more than 0.025%, investigate to determine if this can be improved in the network.
