Viewing and Responding to Alarms
Cisco MGX switches display alarm information about the switch cards and store this information 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
All cards have LEDs for viewing alarm status and switches for responding to alarms. The "Illustrated Card List" chapter in the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Hardware Installation Guide, Releases 2 Through 5 describes the LEDs for all cards that can be installed in the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 switches.
Note
Although there are LEDs for critical, major, and minor alarms on the PXM45 and PXM1E cards, 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. If there were 2 major alarms and 10 minor alarms, the switch would set the major alarm LED to on.
Displaying Alarm Reports in the CLI
You can use a CLI session to view the status of node alarms. Alarms are reported in the following categories:
•
•
•
•
•
•
The sections that follow describe 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:
M8830_CH.1.PXM.a > dspndalmsThe following example shows the node alarm report display.
M8830_CH.1.PXM.a > dspndalmsNode Alarm SummaryAlarm Type Critical Major Minor---------- -------- ------- -------Clock Alarms 0 0 0Switching Alarms 0 0 0Environment Alarms 0 0 0Card Alarms 3 2 0Node License Alarm 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 Clock Alarms
Cisco MGX switches monitor the quality of the 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:
mgx8850a.2.PXM.a> dspclkalmsThe following is an example clock alarm report:
mgx8850a.2.PXM.a> dspclkalmsmgx8850a System Rev: 03.00 May. 06, 2002 22:47:36 GMTMGX8830 Node Alarm: MINORClock Manager Alarm Summary----------------------------NETWORK CLOCK ALARM : STANDBY LOST PRIMARY REFERENCE : MINORNETWORK CLOCK ALARM : STANDBY LOST SECONDARY REFERENCE : MINORCritical Major Minor000 000 002Displaying Switching Alarms
Switching alarms identify problems with the switching components within the switch. Cisco MGX 8850 (PXM45) and Cisco MGX 8950 support several commands that allow you to display switching alarms.
Note
To display a report of all switching alarms, enter the following command:
M8850_LA.8.PXM.a > dspswalmsThe following example is a sample report showing no switching alarms.

Displaying Environment Alarms
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 dspenvalms command as shown in the following example:

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 at the PXM45 or PXM1E switch prompt:
mgx8830a.2.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:
M8830_CH.1.PXM.a > dspcdalmsCard Alarm SummarySlot Critical Major Minor || Slot Critical Major Minor---- -------- ------- ------- || ---- -------- ------- -------1 1 0 0 || 8 0 0 02 0 0 0 || 9 0 0 03 0 0 0 || 10 0 0 04 0 0 0 || 11 0 0 05 0 0 0 || 12 2 2 06 0 0 0 || 13 0 0 07 0 0 0 || 14 0 0 0Use dspcdalms <slot> to see more detail.The next example shows a card alarm report for an MPSM-T3E3-155 card in slot 12:

Displaying Line Alarms on Service Modules
The service modules generate line alarms when a loss of signal (LOS) alarm occurs.
Table 11-3 lists commands that you can enter to display information about line alarms on service modules.
For detailed information about line alarms on specific service modules, refer to that service module's configuration guide. The service module configuration guides are listed in Table 1-1.
Displaying IMA Alarms
Enter the dspimagrpalms command to display alarm state information for all IMA groups on the current PXM1E-16-T1E1 or AXSM-32-T1E1-E, as shown in the following example:
Unknown.7.PXM.a > dspimagrpalmsGroup Number : 2.1Alarm State : StartUp FeGroup Number : 2.2Alarm State : Other FailureEnter the dspimagrpalm <bay.group> command to display alarm state information for a specific IMA group. Replace bay with the number 1 to specify the lower bay, or 2 to specify the lower bay. Replace group with the IMA group whose alarm status you want to view.
In the following example, the user displays alarm information for the IMA group 2 in the lower bay.
Unknown.7.PXM.a > dspimagrpalm 2.2Group Number : 2.2Alarm State : Other FailureEnter the dspimalnkalms command to display alarm state information for all IMA links on the current PXM1E-16-T1E1 or AXSM-32-T1E1-E, as shown in the following example.
Unknown.7.PXM.a > dspimalnkalmsLink Number : 2.5Alarm State : Lif FailEnter the dspimalnkalm <bay.line> command to display alarm state information for a specific IMA link. Replace bay with the 2 to specify the lower bay. Replace line with number of the line whose alarm status you want to view.
Note
In the following example, the user displays alarm information for the IMA group 5 in the lower bay.
Unknown.7.PXM.a > dspimalnkalm 2.5
Link Number : 2.5Alarm State : Lif Fail
Note
Displaying License Alarms
Enter the dsplicalms command to display alarm state information for MPSM feature licenses. For example:
M8830_CH.1.PXM.a > dsplicalmsM8830_CH System Rev: 04.09 Mar. 08, 2004 09:31:25 GMTMGX8830 Node Alarm: CRITICALSlot Critical Major Minor || Slot Critical Major Minor---- -------- ------- ------- || ---- -------- ------- -------1 0 0 0 || 8 0 0 02 0 0 0 || 9 0 0 03 0 0 0 || 10 0 0 04 0 0 0 || 11 0 0 05 0 0 0 || 12 0 0 06 0 0 0 || 13 0 0 07 0 0 0 || 14 0 0 0To display license information on all cards, enter the dspliccds command as shown in the following example:
