Dynamic ATM 1483 subinterfaces function identically to static ATM 1483
subinterfaces, except for the manner in which they are created and configured. The
creation of dynamic upper-layer encapsulation types is essentially the same regardless
of whether they are configured over static ATM 1483 subinterfaces or dynamic ATM
1483 subinterfaces.
ATM 1483 Base Profiles
To configure a dynamic ATM 1483 subinterface over a static ATM AAL5 interface,
you must create a base profile. The base profile includes one or more of the following
attributes for the ATM 1483 subinterface, listed alphabetically:
■
advisory-rx-speed—Sets an advisory receive speed for ATM 1483 subinterfaces
that are created with this base profile. For information, see “atm atm1483
advisory-rx-speed” on page 640.
■
atm pvc—Applies encapsulation, traffic-shaping, and OAM parameters to the
range of ATM PVCs configured on the ATM AAL5 interface for use by the dynamic
ATM 1483 subinterface. For information, see “atm pvc” on page 644.
■
auto-configure—Specifies the types of upper-interface encapsulations that are
accepted or detected by the dynamic ATM 1483 subinterface. For information,
see “atm atm1483 auto-configure” on page 640.
■
atm class-vc—Specifies the VC class assigned to the bulk-configured VC ranges
created on the dynamic ATM 1483 subinterfaces associated with this base profile.
For information, see “atm class-vc” on page 643.
■
description—Assigns a description to ATM 1483 subinterfaces that are created
with this base profile. For information, see “atm atm1483 description” on
page 640. You can then set up the router to send this description to AAA by using
the
atm atm1483 export-subinterface-description command, as described in
“Sending Interface Descriptions to AAA” on page 43 in “Configuring ATM” on
page 3.
■
profile—Adds a nested profile assignment, which references another profile that
dynamically configures an upper-interface encapsulation type over the ATM 1483
subinterface. For information, see “atm atm1483 profile” on page 640.
■
subscriber—Configures a local subscriber for a dynamic upper-interface
encapsulation type. For information, see “atm atm1483 subscriber” on page 641.
You can override the base profile assignment for a single ATM PVC that exists within
a bulk-configured VC subrange with a profile that includes debugging attributes. This
feature is useful for troubleshooting problems with the ATM 1483 dynamic
subinterface columns created on the specified PVC. For more information, see
“Overriding Base Profile Assignments” on page 634.
Nested Profile Assignments
The configuration for each dynamic upper-interface encapsulation type might differ,
depending on the column type built by the router. To manage these differences, you
can include one or more nested profile assignments within the ATM 1483 base profile.
A nested profile assignment references another profile that configures attributes for
a dynamic upper-interface encapsulation type. You can create different profiles for
