Configuring Two-Ended Soft PVC and Soft PVP Connections
With two-ended soft PVC provisioning, you can configure a passive half leg on the terminating switch
of a soft PVC. This allows resources on the terminating switch to be reserved for the incoming soft PVC.
Also, the UPC option can be configured for an individual soft PVC allowing traffic policing.
You can configure the passive half-leg (using the two-ended soft PVC feature) with the following
parameters:
Packet discard
A connection traffic table row associated with the half leg
Usage Parameter Control
The passive leg is used provided the traffic parameters of the leg match with the incoming connection
setup request and the leg is in a “Not Connected” state. If the passive leg is not pre-configured, the
default values are used when creating the dynamic leg.
Figure 7-8 shows a soft PVC between ATM switch routers and PVCs configured on both ends connecting
the routers. In this example the passive half-leg is configured at the destination end at ATM
switch router C.
