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, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# callhome
switch(config-callhome)#
Step 3
switch(config-callhome)# no
duplicate-message throttle
switch(config-callhome)# duplicate-message
throttle

Call Home Enable Function

Once you have configured the contact information, you must enable the Call Home function.
To enable the Call Home function, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# callhome
switch(config-callhome)#
Step 3
switch(config-callhome)# enable
callhome enabled successfully
switch(config-callhome)#
switch(config-callhome)# disable
switch(config-callhome)#

Call Home Configuration Distribution

You can enable fabric distribution for all Cisco MDS switches in the fabric. When you perform Call
Home configurations, and distribution is enabled, that configuration is distributed to all the switches in
the fabric.
