Configuring Encapsulation for Data PVCs

The encapsulation method on a data PVC represents the format of the data units that
traverse the circuit. You can use the encapsulation command in ATM VC
Configuration mode to configure the encapsulation method for a data PVC, or to
restore the default encapsulation method, aal5snap.
For example, the following commands configure a data PVC that uses aal5all
encapsulation. Issuing the exit command causes the configuration to take effect.

Configuring Individual ATM PVC Parameters
Use to configure the variable bit rate, real time (VBR-RT) service category on an
ATM data PVC.
You must specify all of the following parameters:
PCR, in Kbps, in the range 0–149760 (for OC3 ATM modules) or 0–599040
(for OC12 ATM modules)
SCR, in Kbps, in the range 0–149760 (for OC3 ATM modules) or 0–599040
(for OC12 ATM modules)
Maximum burst size (MBS), in cells, in the range 0–16777215
You must issue the exit command from ATM VC Configuration mode for the
configuration to take effect.
Example
host1(config-subif-atm-vc)#vbr-rt 200000 30000 400
host1(config-subif-atm-vc)#exit
Use the no version to restore the default service category, UBR without a PCR.
See vbr-rt.
host1(config)#interface atm 3/0.3
host1(config-subif)#pvc 6 0/250
host1(config-subif-atm-vc)#encapsulation aal5all
host1(config-subif-atm-vc)#exit
host1(config-subif)#
Use to configure the encapsulation method on an ATM data PVC.
Specify one of the following encapsulation types:
aal0 Causes the router to receive raw ATM cells on this PVC and forward
the cells without performing AAL5 packet reassembly
aal5all Configures ATM over MPLS passthrough connections; the router
passes through all ATM AAL5 traffic without interpreting it
aal5autoconfig Enables autodetection of the 1483 encapsulation (LLC/SNAP
or VC multiplexed)
