Usage Guidelines
For the connection-loss keyword, jitter-average keyword, and rtt keyword, the reaction does not occur when
the value violates the upper or the lower threshold. The reaction condition is set when the upper threshold is
passed, and it is cleared when values go below the lower threshold.
For the connection-loss keyword and verify-error keyword, thresholds do not apply to the monitored element.
For the jitter-average keyword, packet-loss keyword, and rtt keyword, if the upper threshold for react
threshold type average 3 is configured as 5000 ms and the last three results of the operation are 6000, 6000,
and 5000 ms, the average is 6000 + 6000 + 5000=17000/3 = 5667—therefore violating the 5000-ms upper
threshold. The threshold type average must be configured when setting the type. These keywords are not
available if connection-loss, timeout, or verify-error is specified as the monitored element, because upper and
lower thresholds do not apply to these options.
In IP SLA MPLS LSP monitor reaction configuration mode, only the connection-loss and timeout keywords
are available. If the react command is used in IP SLA MPLS LSP monitor reaction configuration mode, it
configures all operations associated with the monitored provider edge (PE) routers. The configuration is
inherited by all LSP operations that are created automatically by the PE discovery.

Examples
The following example shows how to use the react command with the connection-loss keyword:
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)# ipsla
RP/0/0/CPU0:router(config-ipsla)# reaction operation 432
RP/0/0/CPU0:router(config-ipsla-react)# react connection-loss
RP/0/0/CPU0:router(config-ipsla-react-cond)#
The following example shows how to use the react command with the jitter-average keyword:
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)# ipsla
RP/0/0/CPU0:router(config-ipsla)# reaction operation 432
RP/0/0/CPU0:router(config-ipsla-react)# react jitter-average
RP/0/0/CPU0:router(config-ipsla-react-cond)#
The following example shows how to use the react command with the packet-loss keyword:
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)# ipsla
RP/0/0/CPU0:router(config-ipsla)# reaction operation 432
