Chapter 9: Configuring and Monitoring Alarms

Alarm Severity

Alarms on a Services Router have two severity levels:

■Major (red)—Indicates a critical situation on the router that has resulted from one of the following conditions. A red alarm condition requires immediate action.

■One or more hardware components have failed.

■One or more hardware components have exceeded temperature thresholds.

■An alarm condition configured on an interface has triggered a critical warning.

■Minor (yellow)—Indicates a noncritical condition on the router that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance.

A missing rescue configuration or software license generates a yellow system alarm.

Alarm Conditions

To enable alarms on a Services Router interface, you must select an alarm condition and an alarm severity. In contrast, alarm conditions and severity are preconfigured for chassis alarms and system alarms.

This section contains the following topics:

■Interface Alarm Conditions on page 167

■Chassis Alarm Conditions and Corrective Actions on page 170

■System Alarm Conditions and Corrective Actions on page 172

Interface Alarm Conditions

Table 89 on page 168 lists the interface conditions, sorted by interface type, that you can configure for an alarm. Each alarm condition can be configured to trigger either a major (red) alarm or minor a (yellow) alarm. The corresponding configuration option is included.

For the services stateful firewall filters, NAT, IDS, and IPSec, which operate on an internal adaptive services module within a Services Router, you can configure alarm conditions on the integrated services and services interfaces.
