PVC. Commands that are applied to the individual PVC supersede any
conflicting commands that were specified in the VC class.

Verifying the Virtual Circuit Class Configuration
To verify the virtual circuit class configuration, use the show atm vc command:

Configuring SONET and SDH Framing
The default framing on the ATM OC-3 SPAs is SONET, but the interfaces also support SDH framing.
In ATM environments, the key difference between SONET and SDH framing modes is the type of cell
transmitted when no user or data cells are available. The ATM forum specifies the use of idle cells when
unassigned cells are not being generated. More specifically, in Synchronous Transport Module-X (STM-X)
mode, an ATM interface sends idle cells for cell-rate decoupling. In Synchronous Transport Signal-Xc
(STS-Xc) mode, the ATM interface sends unassigned cells for cell-rate decoupling.
Note
To change the framing type and configure optional parameters, perform the following procedure beginning
in global configuration mode:
SUMMARY STEPS
1.
Router(config)# interface atm slot/subslot/port
2.
Router(config-if)# atm clock internal
3.
Router(config-if)# atm framing {sdh | sonet}
4.
Router(config-if)# [no] atm sonet report {all | b1-tca | b2-tca | b3-tca | default | lais | lrdi | pais | plop | pplm
| prdi | ptim | puneq | sd-ber | sf-ber | slof | slos}
5.
Router(config-if)# [no] atm sonet-threshold {b1-tca value | b2-tca value | b3-tca value | sd-ber value |
sf-ber value}
6.
Router(config-if)# end
