Figure 19-3 ATM PVC Selection
Bumping and ATM PVC Bundles
The ATM Operation, Administration, and Maintenance (OAM) polling mechanisms maintain the
integrity of the PVCs in an ATM PVC bundle. These mechanisms determine whether a PVC is
unavailable or severely congested. If an individual circuit become unavailable, then the device consults
a preset series of rules to determine the course of action to take next. You configure specific parameters
to define these rules.
Figure 19-4 conceptualizes a failed PVC bundle member whose failure calls into effect the configured
bumping rules.
