About Configuring Dynamic ATM 1483 Subinterfaces
This section introduces important concepts that you need to understand before you
configure dynamic ATM 1483 subinterfaces.
Overview and Benefits
When you use dynamic interfaces over static ATM 1483 subinterfaces, you must
configure the ATM interface and each ATM 1483 subinterface, including the ATM
PVC and the attributes of the subinterface. Subinterface attributes include profile
assignments, autoconfiguration settings, and subscriber configurations.
By contrast, when you use dynamic ATM 1483 subinterfaces over static ATM AAL5
interfaces, you use a process called bulk configuration to configure a range of ATM
PVCs that support dynamic interfaces. On receipt of an incoming packet on the
virtual circuit, the router dynamically creates the ATM 1483 subinterface. As part of
the configuration process, you create an ATM 1483 base profile, which can optionally
include nested profile assignments, to define the attributes required to configure the
dynamic ATM 1483 subinterface and the dynamic upper-layer encapsulation types
built over it.
Bulk configuration provides an efficient and timesaving way to specify a range of
ATM PVCs for dynamic ATM 1483 subinterfaces. Because bulk configuration requires
significantly less configuration of the router, it results in reduced output when you
issue the show configuration command to display the current router configuration.
