Monitoring port status in Spectrum using the link down trap

Environment

Release: Any
Component:

Resolution

The following interface attributes are used to monitor the port status in Spectrum using the link down trap:

  • GeneratePortStatusAlarms (0x12a54) - Determines if port status alarms will be asserted or not on this particular port. Valid values are TRUE/Yes or FALSE/No. The default value is TRUE/Yes. When set to FALSE/No, it does not matter the value of AlarmOnLinkDownTrap, no alarm will be generated.
  • AssertLinkDownAlarm (0x12957) - Determines if SPECTRUM should generate a yellow alarm on the device model when a link down trap is received for this port.  Valid values are TRUE/Yes  or FALSE/No. The default value is FALSE/No.
  • AlarmOnLinkDownTrap (0x11fc2) - Determines how SPECTRUM handles a Link Down trap on this particular port. Valid values are  0 (Never) or 1 (Check Status). The default value is 1 (Check Status). When set to 1 (Check Status), before Spectrum will assert an alarm, it will check the ifAdminStatus and ifOperStatus of the interface. If ifAdminStatus is Down, no alarm will be asserted. An alarm will only be asserted if the ifAdminStatus is Up and the ifOperStatus is Down. The alarm generated is the "BAD LINK DETECTED" alarm.
