Chapter 5 AXSM Command Reference
cnfcon
Traffic parameters such as CDV, CTD are entered at both the master and slave endpoints for both the
forward and reverse directions. However, the values of these parameters entered at the slave end are
ignored during call setup. Therefore, you can specify the lcdv, rcdv, lctd, and rctd options at the master
end only.
Routing Parameters
Routing parameter, such as maximum route cost (-mc maxcost) or the routing priority (-rtngprio
routingPriority) need to be entered at the master endpoint only. The values of the parameters entered at
the slave end are ignored during call setup.
You can assign a priority at the master end of an SPVC or SPVP. The PNNI controller routes higher
priority connections before lower priority connections. The user-configurable range for a connection is,
in descending order of priority, 1–15. The default is 8. See cnfpri-routing for a detailed description of
the Priority Routing feature. Also, the cnfpri-routing command lets you configure groups of bandwidth
so that the order of routing also reflects the bandwidth requirements of the connection.
If you use the cnfcon command to modify only the routing priority of a connection, PNNI does not
immediately re-route the connection. Nevertheless, if you run dspcon for such a changed connection at
the master endpoint, it immediately shows the changed priority even before PNNI re-routes the
connection. You can also use the dsppncon command to see the priority of the SVC portion that is
associated with master and slave endpoints. Note that the dsppncon command shows the new priority
only after PNNI re-routes the connection.
Frame Discard
For frame discard (see -frame option), specify this parameter for VCCs only and only at the master
endpoint. This parameter has no meaning at the slave end. Both early packet discard (EPD) and partial
packet discard (PPD) are supported. If you do not specify frame discard here, the connection manager
uses the frame discard flag in the operational SCT. The EPD on the QE depends on the thresholds in the
SCT for the port. If the cells arriving in the COSB exceed the threshold and are dropped, the whole frame
is dropped.
Local-Only Parameters
The parameters CDVT, stats enable, cc enable (specified using -cdvt, -stat, -cc) are significant only at
the endpoint where you enter them. Therefore, they can be different at each end of the connection.
