Viewing and Responding to Alarms

Cisco MGX 8850 and Cisco MGX 8950 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

The PXM45, AXSM, and RPM cards have LEDs for viewing alarm status and switches for responding

to alarms. The following sections describe these controls.

PXM45 Card Controls

Figure 9-1 shows the LEDs and switches available on the front of the PXM45 card. Table 9-1 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. If there were 2 major

alarms and 10 minor alarms, the switch would set the major alarm LED to on.
