The MGX 8850 displays alarm information on the PXM45 and AXSM cards, and it stores information on these inside the switch. This chapter describes how to interpret the alarm LEDs on the switch and how to obtain alarm reports through the CLI.
The PXM45 and AXSM cards host LEDs and switches that you can use to view alarm status and respond to alarms. The following sections describe the controls on each of these cards.
Figure 5-1 shows the LEDs and switches available on the front of the PXM45 card. Table 5-1 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. |
Green Red Yellow Green indicates the Controller port is active. Red indicates a Major alarm on this port. Yellow indicates a Minor alarm on this port. Off indicates the port has not been activated (upped). Green Yellow Red Blinking green indicates the card is in the active state. Slow blink yellow indicates the card is in the standby state. Fast blink yellow indicates the card is in the boot state. Solid red indicates either the card is in the Reset state, the card has failed, or that a back card is missing. Blinking red indicates the card is downloading new software. Blue Blue indicates a Critical Network alarm in the node. Red Red indicates a Major Network alarm in the node. Yellow Yellow indicates a Minor Network alarm in the node. Green Green indicates a network alarm occurred, but has been cleared. Yellow Yellow indicates the ACO switch was pushed to clear the audible alarm indicator, but the alarm condition still exists. Green Off Green indicates that the power supplies in tray "A" are functioning. Off indicates that power supply tray "A" is empty (no power modules). Green Off Green indicates that the power supplies in tray "B" is empty. Off indicates that power supply tray "A" is empty (no power modules). Green Blinking green indicates that there is activity on the LAN Control Port.

Green | Green indicates the line is active and there are no alarms. Red indicates the line is active, but a local alarm has been detected, and yellow indicates that the line is active and a remote alarm has been detected. |
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.
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 > dspndalms
The following is an example of the node alarm report.
pop20two.7.PXM.a > dspndalms Node Alarm Summary Alarm Type Critical Major Minor Clock Alarms 0 0 0 Switching Alarms 0 0 0 Shelf Slot Alarms 0 1 0 Environment Alarms 0 0 0 Alarms From Card 6 15 18
Typically, 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.
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.
|
Note The dspcdalms command must be run at the PXM prompt. If you switch to another type of card and enter the command, the command is reported as unknown. |
The following example shows a partial card alarm report for all cards:
pop20two.7.PXM.a > dspcdalms Node Card Alarm Summary Line Alarm Slot 1 Critical 1 Major 2 Minor 3 Port Alarm Slot 1 Critical 1 Major 2 Minor 3 Channel Alarm Slot 1 Critical 1 Major 2 Minor 3 Line Alarm Slot 8 Critical 1 Major 2 Minor 3 Port Alarm Slot 8 Critical 0 Major 2 Minor 0 Channel Alarm Slot 8 Critical 1 Major 2 Minor 3
The next example shows a card alarm report for an AXSM card in slot 1:
pop20two.7.PXM.a > dspcdalms 1 Node Card Alarm Summary Line Alarm Slot 1 Critical 1 Major 2 Minor 3 Port Alarm Slot 1 Critical 1 Major 2 Minor 3 Channel Alarm Slot 1 Critical 1 Major 2 Minor 3
Here is another example that shows a card alarm report for an AXSM card in slot 8:
pop20two.7.PXM.a > dspcdalms 8 Node Card Alarm Summary Line Alarm Slot 8 Critical 1 Major 2 Minor 3 Port Alarm Slot 8 Critical 0 Major 2 Minor 0 Channel Alarm Slot 8 Critical 1 Major 2 Minor 3
The MGX 8850 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 > dspclkalarms
The following is an example clock alarm report:
pop20two.7.PXM.a > dspclkalarms pop20two System Rev: 02.00 Sep. 02, 2000 23:39:22 GMT MGX8850 Shelf Alarm: NONE Clock Manager Alarm Summary ---------------------------- Critical Major Minor 000 000 000
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 > dspenvalms
The following is an example environmental alarm report:
