4.4.3Deleting Events and Alarms

To delete events or alarms currently logged within your SmartSwitch 9A100, use the delete events and delete alarms commands, respectively.

4.5PVC CONNECTIONS

The SmartSwitch 9A100 supports Permanent Virtual Circuits (PVCs), both point-to-point and point-to-multipoint. Use PVCs to connect devices (that do not support SVCs) to a switch’s local client. Also, use PVCs to make connections through the SmartSwitch 9A100 between devices that support only PVCs.

Use point-to-point PVCs to connect one end node to another for two-way communication. Use point-to-multipoint PVCs to connect a broadcast end node to a group of receiving end nodes; traffic is one way.

Note PVCs use traffic descriptors to define their traffic characteristics. If you are unfamiliar with traffic descriptors, see Section 4.6.1, “Traffic Descriptors.”
