Creating soft PVC and PVP connections consists of the following general steps:
• Configure a target port and ATM target address on the target switch
• Create a traffic descriptor to be used by the connection
• Add a soft PVC (or PVP) on the source switch that specifies the port on the target switch as its end

5.4.3 Creating a soft PVC
The following is a step-by-step example of creating a soft PVC from port 7a1 on the source switch to port 6b3 on the
target switch. The two switches containing the soft PVC are separated by several switches, which are connected
through PNNI (see Figure 5-2 and Figure 5-3).
