Quickstart Provisioning Procedures
SVC Configuration Quickstart
Switched virtual circuits (SVCs) are the solution for on-demand connections. They are set up as needed
and torn down when no longer needed. To enable this dynamic activity, SVCs use signaling. End systems
request connectivity to other end systems and, provided that the requested services are available, the
connection is set up at the time of the request. When idle, an SVC is taken down to save network
bandwidth.
Cisco MGX 8850 (PXM1E) and Cisco MGX 8830 switches can use the PNNI protocol to determine how
to set up SVCs through the network. Because the switch automatically sets up SVCs, you do not have to
configure SVC routes. However, the switch must be configured correctly before it can set up SVCs. The
following quickstart procedure summarizes the tasks required to enable SVC communications. With the
exception of CPE configuration, all these tasks are described in this chapter.
Note
The tasks in the following procedure do not have to be completed in the order presented. However, all
tasks must be completed before SVCs will operate.
Step 9 uppnport <portid> Bring up the port after configuration is complete.
Step 10 upilmi <ifNum> <partId>
cnfilmi <options>
Related commands:
dspports
dspilmis
Configure and start ILMI on the port. This step is required for
dynamic addressing and the ILMI automatic configuration
feature. Otherwise, it is optional.
See the “ Configuring ILMI on a Port ” section later in this chapter.

Command Purpose
Step 1
See the “ ATM Trunk
Configuration Quickstart ” section
earlier in this chapter.
Configure the trunks that link the switches through which the
ATM end stations connect. Be sure to add the PNNI controller on
each switch and select that controller when partitioning trunks.
Step 2
dsppnni-reachable-addr
network Verify connectivity between the node pairs that will host SVCs.
See the “ Verifying End-to-End PNNI Communications ” section
later in this chapter.
Step 3 See the “ PNNI UNI Port
Configuration Quickstart ” section
earlier in this chapter.
Configure UNI ports for the ATM end stations at each end of the
SVC, and assign either static or dynamic addressing to each line.
Be sure to add the PNNI controller on each switch and select that
controller when partitioning trunks.
Step 4
See the CPE documentation. Configure CPE devices for communications with the switch
through the UNI ports configured in the previous step.
Step 5
dsppncons This optional step displays the SVC connections that are
operating.
See the “ Displaying SVCs ” section in Chapter 9, “Switch
Operating Procedures.”
