Interface Performance


This chapter describes how to view performance information for each of the interfaces on the Cisco 12000 series internet router you are managing, using the Cisco 12000 Manager (C12kM) application.

There are two performance options in C12kM: the Interface Performance windows and the Cisco Element Management Framework (Cisco EMF) Performance Manager application. Performance Manager displays historical data as well as current data in the form of a line chart, bar chart, or table; Interface Performance windows display only current data in a raw numerical format.


Note Refer to the "Performance Management and Historical Data" chapter for information on viewing historical performance information for a selected chassis, module, or interface using the Performance Manager application.

Interfaces and Related Technology-Specific Windows

Interfaces on line cards can support multiple technologies. Performance windows are technology-specific. For example, an POS interface supports two technologies: Generic and SONET.

Therefore, to view the performance of a POS interface, you need to view two windows: the Generic Interface Performance window, and the SONET Interface Performance window.

This same process is applicable to all different types of interfaces: POS, DS-3, ATM, SRP or Ethernet.

Table 10-1 details which technology-specific performance windows apply to each interface type.

Generic Interface Performance

The Generic Interface Performance section covers the following areas:

Viewing the Generic Interface Performance Window

Starting Performance Logging for a Selected Interface

Stopping Performance Logging for a Selected Interface

Generic Interface Performance Window—Detailed Description

Viewing the Generic Interface Performance Window

To view the Interface Performance window, proceed as follows:


Step 1 Right click (on a relevant object icon in the Map Viewer window or from an object pick list) and select the C12kM Management>Physical>Interface>Generic>Performance option. Refer to Table 10-1 for information on which objects allow you to launch the Interface Performance window. The Interface Performance window appears, with the Performance (1) tab displayed:

Figure 10-1 Interface Performance Window—Performance 1 Tab

Step 2 Choose a Chassis, Module, and Interface from the list boxes displayed at the left of the window. The interface performance information for the selected interface appears in the tabs at right.


Note Transmitted/Received Bandwidth Utilization will not be calculated and displayed until after a performance logging poll (15 minutes), and only if performance logging is active for the interface.


Step 3 Choose the Performance(2) tab, if required.

Figure 10-2 Interface Performance Window—Performance 2 Tab

The Error Statistics for the selected interface appear.

Step 4 Choose the Performance (3) tab, if required.

The Packets/Octets statistics for the selected interface appears.


Starting Performance Logging for a Selected Interface


Note Performance logging can also be started/stopped on a global basis for a selected chassis. Refer to the "Starting Global Performance Logging" section. Performance logging can also be started on a per module (GRP) basis. For details on how to start performance logging for a selected module (GRP), refer to the "Module Performance" section.


Starting performance logging allows performance data to be gathered for the selected interface. Performance polling occurs every polling period (15 minutes). Performance data is then gathered and stored for historical review. Current performance data can be viewed in the Interface Performance window, or you can view historical performance data in Performance Manager.


Note You must start performance logging if you want to view historical data in the Performance Manager. You do not need to have performance logging enabled on an interface to view the current data in the Interface Performance window.


To start performance logging for a selected interface, proceed as follows:


Step 1 Open the Interface Performance window. Refer to the "Viewing the Generic Interface Performance Window" section for further details.

Step 2 Choose a Chassis, Module, and Interface from the lists displayed at the left of the window.

Step 3 Click Start to begin performance logging for the selected interface. A window appears for you to confirm that you wish to start performance logging.

Figure 10-4 Start Performance Logging Confirmation Window

Step 4 Choose Yes to begin performance logging for the selected interface. An Action Report window appears to confirm that performance logging has started.

Figure 10-5 Action Report Window

Step 5 Choose Close to close the Action Report window.

Step 6 Choose Close from the File menu to close the Interface Performance window.

Refer to the "Performance Management and Historical Data"chapter for information on viewing historical performance information for a selected interface.
