Configuring ATM 1483 Dynamic Subinterfaces
Use the no version to remove the VC class association with the base profile.
See atm class-vc.
Use to apply encapsulation, traffic-shaping, and OAM parameters to the range
of ATM PVCs configured on an ATM AAL5 interface for use by a dynamic ATM
1483 subinterface.
Include this command in the base profile for a dynamic ATM 1483 subinterface.
You must specify one of the following encapsulation types:
aal5autoconfig Enables autodetection of the 1483 encapsulation (LLC/SNAP
or VC multiplexed)
aal5snap Specifies a logical link control (LLC) encapsulated circuit; the
LLC/Subnetwork Access Protocol (LLC/SNAP) header precedes the protocol
datagram
aal5mux ip Specifies a VC-based multiplexed circuit used for IP only
You can optionally set the peak, average, and burst sizes. To use VBR-RT or
VBR-NRT as the service type, you must specify each of these options.
The default service type is UBR. To set a different service type, specify one of
the following keywords:
rt Selects VBR-RT as the service type; you can select rt only if you set the
peak, average, and burst parameters
cbr Selects CBR as the service type; you must set the CBR rate in Kbps
You can optionally include the oam keyword and a number of seconds in the
range 1–600 to enable generation of OAM F5 loopback cells on this circuit. This
option enables VC integrity features that affect the operational state of the ATM
PVC.
Example
host1(config-profile)#atm pvc aal5autoconfig cbr 10000 oam 120
Use the no version to restore the default service type, UBR, on the VC range.
See atm pvc.
Use to configure the static ATM AAL5 interface to support autodetection of an
ATM 1483 dynamic interface type.
You must issue this command to enable creation of a dynamic ATM 1483
subinterface.
Example
host1(config-if)#auto-configure atm1483
