Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing PNNI Routes
Note There are other optional parameters that you can set using the addcon and cnfcon commands,
but they do not appear in Table 8-7 because you do not need to set them when you are associating
an SPVC or SPVP with a preferred route. For information on all the command parameters for
PXM1E cards, see Chapter 4, “Preparing Service Modules for Communication.” For
information on all the addcon and cnfcon command parameters a service module, refer to the
appropriate service module guide, all of which are listed in Table 1-1.
Step 5 Enter the dspcon <portid> <vpi> <vci> command to ensure that the SPVC/SPVP has been configured
properly and is associated with the preferred route you set up in Step 1. Replace <portid> with the port
identifier in the format slot:bay.line:ifnum. Replace <vpi> with the virtual path identifier for the
connection. Replace <vpi> with the virtual circuit identifier for the connection.
Table 8-7 addcon and cnfcon Preferred Route Command Parameters
Parameter Description
ifNum Logical interface (or port) number. This ifNum corresponds to the ifNum added
through the addport command. The range is 1-31.
vpi Virtual path identifier value in the range 0-255 (UNI) or 0-4095 (NNI or VNNI).
For VNNI, specify one VPI per port.
vci Virtual connection identifier (VCI):
For a VCC on a UNI, the range is 1-4095. On an NNI or VNNI, the VCI range is
1-65535.
For MPLS, the recommended minimum VCI is 35.
For a VPC, the vci is 0.
mastership Value to specify the endpoint as master or slave:
• 1 or `m' specifies the master end.
• 2 or `s' specifies the slave end.
-prefrte Associates a preferred route (preferredRouteId) to the connection. Use this
optional parameter at the master endpoint only.
Range: 0-65535
Default: 0
-directrte Specifies that the connection can take only the preferred route associated through
the -prefrte parameter.
Use this optional parameter at the master endpoint only. To remove this
requirement from the connection, use the cnfcon command and specify a 0 for the
parameter. The possible values are as follows:
• 1: yes (make the preferred route required)
• 0: no (do not require the connection to take the preferred route)
Default: no (0)
