Wait Before Sending a
Duplicate Alert
Duplicate Alert
Specifies the time interval for duplicate alerts. There are two settings:
Initial Number of Seconds to Wait Before Sending a Duplicate Alert. If
you set this value to 0, duplicate alert summaries are not sent and instead, all
duplicate alerts are sent without any delay (this can lead to a large amount of
email over a short amount of time). The number of seconds to wait between
sending duplicate alerts (alert interval) is increased after each alert is sent.
The increase is the number of seconds to wait plus twice the last interval. So
a 5 second wait would have alerts sent at 5 seconds, 15, seconds, 35 seconds,
75 seconds, 155 seconds, 315 seconds, etc.

Maximum Number of Seconds to Wait Before Sending a Duplicate Alert.
You can set a cap on the number of seconds to wait between intervals via the
maximum number of seconds to wait before sending a duplicate alert field.
For example, if you set the initial value to 5 seconds, and the maximum value
to 60 seconds, alerts would be sent at 5 seconds, 15 seconds, 35 seconds, 60
seconds, 120 seconds, etc

Cisco AutoSupport

•
a copy of all alert messages generated by the system
•
weekly reports noting the uptime of the system, the output of the
status
command, and the AsyncOS version used.

message sent to Cisco. This applies only to recipients that are set to receive
System alerts at Information severity level.
