Fault Management

Fault data is available for managed chassis, module, and interface objects regarding the overall management connectivity and environmental aspects. Fault management functionality is supplemental to the processing of alarm notifications from the Cisco Catalyst 8500 router. Some data the fault management windows provide lead to alarms, while other data is purely statistical and may not require further action. For information on the alarms supported, see "Alarms".

Not all the data which the fault management windows provide produce alarms. Alarms occur when specific system occurrences coincide with the definitions of SNMP traps. If the set trap data is met, Cisco EMF translates the trap data into an alarm. For further information on traps and alarms, see the "Alarms".

Fault information for both chassis and module objects provides availability data, including up time, the most recent object change and restart. In addition, module fault data indicates the operational status and the amount of free memory. Chassis fault data extends to environmental fault management information. Environmental fault management data displays in the form of four tables that report on the status of power supplies, voltage, temperature and fans within the chassis. Each table contains a column that indicates the current state of each testpoint. This can be either Normal, Warning, Critical, Shutdown or Not Present. The C8500MGR currently does not present power supply, voltage, temperature, or fan fault data.

Interface fault management is only applicable to ATM interfaces. The data which displays consists of statistical count of errors the interface encounters, including total number of errors, transmit errors, SONET errors, and DS1/E1/DS3/E3 errors.

The Fault Management chapter covers the following:

Chassis Fault Management

The Chassis Fault Management window is a read-only window that provides fault information for a selected chassis.

To view the Chassis Fault Management 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 choose Cisco 8500 Series Manager > Fault > (Chassis >) Fault Management. For information on which objects allow you to launch the Chassis Fault Management window, see "EM Windows".

The Chassis Fault Management window appears displaying the General tab.

Step 2 Select the Chassis for which you want to view fault data from the Chassis list box at left of the window.

Chassis-level fault information displays in the areas to the right.

Chassis-level fault information displays in the General tab as follows:

Up Time—Displays the up time after the last reset.
Last Changed Time—Displays the time the chassis hardware was last modified.
Last Restart Reason—Displays the reason for the last restart.
Last Authentication Failure Address—Displays the last authorization failure IP address for the selected chassis. The Last Authentication Failure Address field refers to the fact that the SNMP agent on the router has received a protocol message that is not properly authenticated. The IP address is the source of the message. This is a security issue which requires investigation.
Clock Source Status—Displays the configured clock source status.

The LED Status area displays colored indicators for the processor card and the Ethernet link status.

The Cisco Contact Details area displays contact resources.

Step 3 Click the Power Supply tab.

The power supply and voltage details for the chassis appear. The C8500MGR currently does not support power supply fault data.

Figure 6-2 Chassis Fault Management Window—Power Supply Tab

Tip Text wider than the column width truncates. Column width alteration is possible, allowing you to view information within the column more clearly. To change the width of a column: (1) Move the mouse pointer to the left of the column heading. The mouse pointer changes to a double headed arrow. (2) Click and hold the left mouse button. A line appears down the length of the column. (3) Drag the line to the desired width, then release the mouse button. Columns return to their default width when you close the window.

The Power Supply pane displays the following information for each power supply (in tabular format):

Description—Textual information for the power supply
State—Current state of the power supply; possible state values can be Normal, Warning, Critical, Shutdown, or Not Present
Source—Power supply source; possible source values are: unknown, ac, dc, external, or internal redundant

The Voltage pane displays the following (in tabular format):

Description—Textual information on voltage
Status Value—Current status of the voltage for the selected chassis
Minimum Threshold—Lowest status value assigned before a shutdown is initiated and notifications generated
Maximum Threshold—Highest status value assigned before a shutdown is initiated and notifications generated

The minimum and maximum threshold values specify the range that can be associated with the object before an emergency shutdown is initiated.

Last Shutdown—Last shutdown initiation
State—Current voltage state; possible state values can be Normal, Warning, Critical, Shutdown or Not Present

If required, use the More (arrow) button in either pane to view all of the information.

Step 4 Click the Temperature tab.

The temperature details for the selected chassis appear. The C8500MGR currently does not support temperature fault data.

Figure 6-3 Chassis Fault Management Window—Temperature Tab

The Temperature pane displays the following details for the core temperature status and the inlet temperature status:

Description—Textual information on temperature for the selected chassis
Status Value—Current status value of the temperature of the selected chassis
Threshold—Highest value associated with the object before a shutdown is initiated
Last Shutdown—Status of the chassis when shutdown was last initiated
State—Current temperature state of the selected chassis; possible state values can be Normal, Warning, Critical, Shutdown or Not Present

If required, use the More (arrow) button in either pane to view all of the information.

Step 5 Click the Fan tab.

The fan details for the selected chassis appear in the tab. The C8500MGR currently does not support fan fault data.

Figure 6-4 Chassis Fault Management Window—Fan Tab

The Fan pane displays a description and the current state of the fan status (in tabular format) as follows:

Fan Status—Status of the fan module, typically OK
Description—Textual information for the fan
State—Current state of the fan in the selected chassis; possible state values can be Normal, Warning, Critical, Shutdown or Not Present

If required, use the More (arrow) button in either pane to view all of the information.

Step 6 Review the data on each tab as necessary.

Step 7 Choose File > Close to close the Chassis Fault Management window.

Module Fault Management

The Module Fault Management window is a read-only window that provides fault information for a selected module.

To view the Module Fault Management 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 choose Cisco 8500 Series Manager > Fault > (Module >) Fault Management. For information on which objects allow you to launch the Module Fault Management window, see "EM Windows".

The Module Fault Management window appears.

Figure 6-5 Module Fault Management Window

Step 2 Select a chassis from the Chassis list box at left of the window, then select a module from the Module list box.

Fault information for the selected module appears, along with Cisco contact resources. The Module Availability area displays the following:
