Technical Tip: What are the entries under "Alarm Configuration" for an interface model for?
CA Spectrum Technical Tip by Joe Ackley, Principal Support Engineer
Description:
In CA Spectrum, in the Information tab for of an interface model, there is a subview labeled "Alarm Configuration". In this "Alarm Configuration" subview are the following two entries:
Generate Alarm on Port - Default value is Yes
Generate Alarm on Device - Default value is No
What do these two entries mean? What alarms do they control?
Solution:
The "Generate Alarm on Port" is associated with the GeneratePortStatusAlarms Attribute ID: 0x12a54 which indicates whether a port status alarm is generated on this port. or not Specifically the Critical "BAD LINK DETECTED" alarm. When "Generate Alarm on Port" is set to "Yes" and at least one of the following is enabled, a "BAD LINK DETECTED" alarm will be asserted on the interface model by Spectrum:
PollPostStatus
Live Links (Pipes)
Link Down Trap
Port Fault Correlation
When "Generate Alarm on Port" is set to "No", a "BAD LINK DETECTED" alarm will not be asserted on the interface model by Spectrum even if at least one of the above is enabled.
The "Generate Alarm on Device" is associated with the AssertLinkDownAlarm Attribute ID: 0x12957 which determines whether CA Spectrum generates a Minor (yellow) alarm on the device model when a link-down trap is received for this port. This is different from the Critical "BAD LINK DETECTED" alarm that can be generated on the interface model when a link down trap is received.
