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 (PXM45) and Cisco MGX 8950 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 10
cnfaddrreg
addaddr
Related commands:
dsppnports
dspatmaddr
deladdr
Configure static ATM addresses for ports that require them.
See the “Assigning Static ATM Addresses to Destination Ports”
section on page 3-46.
Step 11
addprfx
Related commands:
cnfaddrreg
dspprfx
If dynamic addressing is to be used on a port, define an ATM
address prefix that ILMI can use when assigning addresses.
See the “Configuring ILMI Dynamic Addressing” section on
page 3-50.
Step 12
uppnport Bring up the port after configuration is complete.
Step 13
cc Change back to the AXSM card.
Step 14
upilmi
cnfilmi
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 on page 3-47.
