Viewing and Responding to Alarms
The MGX 8850 switch displays alarm information on the PXM45 and AXSM cards, and it stores information on these cards inside the switch. This chapter describes how to interpret the alarm LEDs on the switch and how to obtain alarm reports through the CLI.
Viewing and Responding to Alarms Using Physical Switch Controls
The PXM45and AXSM cards have LEDs for viewing alarm status and switches for responding to alarms. The following sections describe these controls.
PXM45 Card Controls
Figure 8-1 shows the LEDs and switches available on the front of the PXM45 card. Table 8-1 describes these controls.
Note
Although there are LEDs for critical, major, and minor alarms on the PXM45, only one of these LEDs is set to on when multiple alarms are active. The switch always displays the status of the most severe alarm. Critical alarms are the most severe, and minor alarms are the least severe. For example if there were 2 major alarms and 10 minor alarms, the switch would set the major alarm LED to on.

AXSM Card Controls
Figure 8-2 shows the LEDs available on the front of the AXSM card. Table 8-2 describes these LEDs.

Displaying Alarm Reports in the CLI
You can use a CLI session to view the status of switch alarms. Alarms are reported in the following categories:
•
•
•
•
•
•
•
This section describes how to display the different types of alarm reports.
Note
Displaying Node Alarms
A node alarm report displays a summary report of all alarms on the node. To display node alarms, enter the following command:
pop20two.7.PXM.a > dspndalmsThe following is an example of the node alarm report.
pop20one.7.PXM.a > dspndalmsNode Alarm SummaryAlarm Type Critical Major Minor---------- -------- ------- -------Clock Alarms 0 0 0Switching Alarms 0 0 0Environment Alarms 0 0 0Card Alarms 0 0 0Typically, you would start investigating alarms by displaying the node alarms. Once you have identified the area that is producing the alarms, you would enter additional commands to display detailed information on those alarms. The following sections describe how to display these detailed reports.
Displaying Card Alarms
A card alarm report can display the alarm status of all the cards within the node or the alarm status of a single card. To display card alarms, enter the following command:
pop20two.7.PXM.a > dspcdalms [slot]Replace slot with the number of the card for which you want to display alarms. If you omit the slot number, the switch displays the alarms for all cards in the node as shown in the following example:
pop20one.7.PXM.a > dspcdalmsCard Alarm SummarySlot Critical Major Minor---- -------- ------- -------1 0 0 02 0 0 03 0 0 04 0 0 05 0 0 06 0 0 07 0 0 08 0 0 09 0 0 010 0 0 011 0 0 012 0 0 013 0 0 014 0 0 0Use dspcdalms <slot> to see more detail.The next example shows a card alarm report for an AXSM card in slot 1:

The MGX 8850 switch monitors the quality of its clock sources. If the timing for a clock source strays beyond the tolerance thresholds, an alarm is reported. To view the clock alarms, enter the following command:
pop20two.7.PXM.a > dspclkalarmsThe following is an example clock alarm report:

An environmental alarm report displays the alarm status and operating statistics for the switch power supplies and cooling fans. To display the environmental alarm report, enter the following command:
pop20two.7.PXM.a > dspenvalmsThe following is an example environmental alarm report:

Displaying Log File Information
Log files record switch events such as operator login and command entry. To view the contents of the current log, enter the following command:
pop20two.7.PXM.a > dsplog [-sl <slot>] [-mod CLI]To limit the log display to the events for a single slot, use the -sl option and replace slot with the appropriate slot number.
To limit the log display to CLI events, use the -mod option with the CLI keyword.
To display a list of archived log files, enter the following command:
pop20two.7.PXM.a > dsplogsThe log files are stored in the C:/LOG directory.
