NMC-RX 7.2.x User Guide, Vol. 1 > Configuring ATM > Viewing ATM Statistics

Viewing ATM Statistics

The NMC-RX application allows you to view and monitor information about ATM major interfaces, subinterfaces, circuits, and OAM F4 circuits. Once you select a configured device, you simply list the objects and request statistics, and a Statistics tab is displayed.

To view statistics:

1. From the Device-wide Explorer, select ATM, and click either Interfaces, Sub Interfaces, Circuits, or OAM F4 Circuits.
2. Right-click, and select List All.

A list of all objects of the type you selected, which are configured on the device, appears in the list area.

3. From the list, select the interface, subinterface, circuit, or OAM F4 circuits for which you want to view statistics, right-click, and select Statistics. The appropriate Statistics tab appears. Refer to the following sections for descriptions.
