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:
•
Node alarms
•
Clock alarms
•
Switching alarms (On Cisco MGX 8850 (PXM45) and Cisco MGX 8950 switches only)
•
Environment alarms
•
Card alarms
•
License alarms
The sections that follow describe how to display the different types of alarm reports.
