About Duplicate Message Throttle

If a Call Home message is sent multiple times from the switch within a short period of time, you may be swamped with a large number of duplicate messages. To avoid this situation you can limit the number of messages received for the same event. By default, this feature is enabled in all switches in the Cisco MDS 9000 Family. When enabled, if the number of messages sent exceeds the maximum limit of 30 messages within the 2-hour timeframe, then further messages for that alert type are discarded within that timeframe.

To enable message throttling in a Cisco MDS 9000 Family switch using Fabric Manager, follow these steps:

  1. Select a switch in the Fabric pane.
  2. Expand Switches, expand Events, and select Call Home in the Physical Attributes pane.
  3. Click the Control tab.
  4. Select a switch in the Information pane.
  5. Check the Duplicate Message Throttle check box.
  6. Click the Apply Changes icon.
