Changing Alarm Settings
Use Alarm Settings to enable individual alarms, set the retention period for alarms, and to specify the number of events to keep for each alarm. The Alarm Setup tab of Preferences has two sub-tabs:
- Alarms Settings, for enabling alarms and changing the severity setting for the alarm. All of the alarms on this page are preconfigured and enabled by default.
- Retention, for setting the retention period for alarms and for specifying the number of events to keep for each alarm.
This section describes:
Changing the Severity of Individual Alarms
You can change the severity of the alarms to match your corporate procedures and guidelines. For example, at your company a DoS attack might be considered a critical alarm, but Network Director has a default severity for DoS attacks as a major alarm.
To change the severity of an alarm:
- Select the Severity in the specific alarm entry on the Alarm Setup page. A list of the severity levels appear.
- Select the new severity level for the alarm.
- Click OK and Yes to confirm the change to the severity setting.
Enabling Alarms
Ensure all devices are configured to send traps to Network Director. This task is performed for the devices in Deploy mode through Set SNMP Trap Configuration.
Use the Alarm Setup tab on the Alarm Settings page to disable and re-enable individual alarms or all alarms. Fault alarms are preconfigured and initially enabled. To enable or disable alarms:
- (Optional) Sort the alarms. By default, the list of alarms is sorted alphabetically within each category. You can also sort by description or alarm severity within a category by clicking a column heading.
- Review the alarms and either select the check box in the heading to select all of the alarms or select the check box for the individual alarms you want to enable. For a full description of each of the alarms, view Table 1.
- Click OK and Yes to verify the alarm change.
Table 1: Alarm Descriptions
Alarm Name | Description | Device Type |
|---|---|---|
AP and Radio (APAndRadio) | ||
AP License Limit Exceeded | Generated when the number of wireless LAN access points (WLAs) exceed the number of licenses configured on a wireless switch. The trap occurs when a wireless switch receives a packet from an inactive access point. The switch is unable to attach the access point without exceeding the maximum (licensed) number of active access points. | Wireless LAN controller |
AP Manager Changed Alarm | Generated when the access point’s secondary link becomes the primary link. | Wireless LAN controller |
AP Status Alarm | Generated when an access point changes state. | Wireless LAN controller |
AP Tunnel Limit Exceeded | Generated when the number of tunnels per access point are exceeded. This alarm is generated by the access point’s Primary Access Manager (PAM) when the access point rejects a tunnel creation request because it has already created the maximum number of tunnels it can support. | Wireless LAN controller |

WLC Tunnel Limit Exceeded | Generated when the wireless switch rejects a tunnel creation request because it has reached the maximum number of tunnels supported. When the trap event trpzWsTunnelLimitType equals the platform-tunnel-limit, the wireless switch has reached the maximum tunnel capacity. The actual tunnel limit varies by platform. When the trap trpzWsTunnelLimitType equals ap-ws-tunnel-limit, the wireless switch has reached the access point-to-switch tunnel’s limit. The value of that limit depends on the current situation of the wireless switch (mobility domain, network domain, network resiliency status). | Wireless LAN controller |

Retaining Alarm History
Use the Retention tab on the Alarm Settings page to specify the number of days to keep alarm history. The default retention time is 120 days; but you can specify a period of 7 through 1000 days. Specifying a longer retention time consumes more database resources. To change the alarm retention duration, type a new value and click OK and Yes to verify the change.
Specifying Event History
The Events per Alarm field enables you specify the number of event entries that are kept in the alarm history. This field is found on the Retention tab on the Alarm Settings page. The default setting for events is 20. To change the setting, type a new value and click OK and Yes to verify the change.
