Configure external alarm contacts to trigger alarms for external devices with specified trigger conditions and severity levels.

Configure external alarms to monitor and alert on the status of external devices in your environment, allowing you to set appropriate trigger conditions and severity levels for different alarm scenarios.

Configure an open or closed circuit to trigger an alarm for the external devices in your environment and configure the severity of the alarm.

Procedure

SUMMARY STEPS

  1. Use the configure terminal command to enter global configuration mode.
  2. (Optional) Use the alarm contact contact-number description string command to configure a description for the alarm contact number.
  3. Use the alarm contact {contact-number | all } { severity { critical | major | minor } | trigger { closed | open }} command to configure the trigger and severity for an alarm contact number or for all contact numbers.
  4. Use the show env alarm-contact command to show the configured alarm contacts.
  5. Use the end command to exit to privileged EXEC mode.
