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 8800/8900 Hardware Installation Guide, Releases 2 - 5.1 describes the LEDs for all cards that can be installed in the MGX 8850 (PXM1E/PXM45), MGX 8950, and 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:

•Node alarms

•Clock alarms

•Switching alarms (on MGX 8850 (PXM45) and MGX 8950 switches only)

•Environment alarms

•Card alarms

•License alarms

The sections that follow describe how to display the different types of alarm reports.

---

Note The procedures in the following sections can be completed by users at all access levels.

---

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 > dspndalms

The following example shows the node alarm report display.

M8830_CH.1.PXM.a > dspndalms

Node Alarm Summary

Environment Alarms                   0             0              0

Card Alarms                          3             2              0

Node License Alarm                   0             0              0

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.

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> dspclkalms

The following is an example clock alarm report:

mgx8850a.2.PXM.a> dspclkalms

mgx8850a                          System Rev: 03.00   May. 06, 2002 22:47:36 GMT

Displaying Switching Alarms

Switching alarms identify problems with the switching components within the switch. MGX 8850 (PXM45) and MGX 8950 support several commands that allow you to display switching alarms.

---

Note PXM1E do not support switching alarms. Therefore, the commands in this section do not apply to MGX 8850 (PXM1E) and MGX 8830 switches.

---

To display a report of all switching alarms, enter the following command:

M8850_LA.8.PXM.a > dspswalms

The following example is a sample report showing no switching alarms.

M8850_LA.8.PXM.a > dspswalms

When the switch reports xbar alarms, you can use the troubleshooting commands in Table 11-1 to collect more information.

Table 11-1 Crossbar Alarm Troubleshooting Commands 

Command	Purpose
dspxbar <slot> <plane>	Displays the following general information about the configuration of a switch plane (or switching fabric or crossbar): •Number of the slot where the crossbar ASIC resides (7 or 8 for a MGX 8850 (PXM1E) node, 9, 10, 25, or 26 for a MGX 8950 node). •Selected switch plane or ASIC number. The range is 0 to 3. If you do not specify a plane with this command, the default value of 0 is used. •Revision number of the ASIC. •Status of the ASIC.The status is either failed or OK. If the status is failed, the other ASICs must carry the switching load, and the throughput of the switch falls below the maximum. In this case, Cisco Systems recommends you replace the card. The cell grant mode is always "Multicast Preferred." •The "Resent Sframe Tic" is the rising edge of the clock. "Sframe" refers to a switch frame.
dspdeverrhist XBARCORE -pslot *	Displays a historical count of errors.
dspdeverr XBARCORE -pslot *	Displays the current count of errors.
dspxbarerrthresh	Displays the thresholds for crossbar errors. The following items that make up a threshold are as follows: •Duration of the error state •Number of errors during that time period •Upper and lower error counts within a particular alarm severity (minor, major, and critical) Thresholds are displayed for the following errors: •Loss of synchronization (LossOfSync) •Transceiver error (TranscieverErr) •DisparityErr—an accumulation of five ASIC-level errors •ParityErr—a parity error in the switch frame as a whole •HeaderCRCErr—a CRC error for the switch frame header •PayloadCRCErr—a CRC error for the switch frame payload •RemapTwiceErr •RemapRecurrErr •Backpressure parity error (B.P.ParityErr)—a parity error in the signaling for backpressure
dspxbarmgmt	Displays details about the load sharing configuration for the node.
dspxbarstatus	Displays status of each slot for a crossbar.

For more information on these commands, refer to the Cisco MGX 8800/8900 Series Command Reference, Release 5.1.

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:

mgx8830a.2.PXM.a > dspenvalms
