Duplicate Message Throttle

You can configure a throttling mechanism to limit the number of Call Home messages received for the
same event. If the same 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.
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 time frame, then
further messages for that alert type are discarded within that time frame. You cannot modify the time
frame or the message counter limit.
If 2 hours have elapsed since the first such message was sent and a new message has to be sent, then the
new message is sent and the time frame is reset to the time when the new message was sent and the count
is reset to 1.
To enable message throttling in a Cisco MDS 9000 Family switch using Fabric Manager, follow these
steps:
Step 1 Select a switch in the Fabric pane.
Step 2 Expand Switches, expand Events, and select Call Home in the Physical Attributes pane.
You see the Call Home information in the Information pane.
