Different subnets alert


The details shown below are based on the default settings. Options for editing this alert don’t include the ability to edit the trigger or clear condition definitions. You can specify whether the alert should clear based on how it’s configured, or whether it should have no clear condition and be cleared manually.


Primary purpose: Notify that two connected interfaces don’t have matched subnets (different ranges, different subnet masks).

Alert severity


Repetitive alert pause condition

After 5 occurrences within 2 hours against a specific entity, pause the alert for 24 hours

Alert trigger condition

Physically connected routed interfaces have different subnets.

Alert clear condition

Misconfiguration has been resolved.

Action(s) to be taken

  • Check the device’s configuration and add correct subnet to the affected interface.
  • Ensure traffic is flowing through the interfaces over the subnet after the change.
