PurposeCommand or Action
(Optional) Specifies the number of seconds to keep the
operation in memory when it is not actively collecting
ageout seconds
Example:
RP/0/RSP0/CPU0:router(config-ipsla-sched)# ageout
3600
Step 16
information. The default value of 0 seconds means that
the operation never times out.
(Optional) Specifies that the operation starts automatically
at the specified time and for the specified duration every
day.
recurring
Example:
RP/0/RSP0/CPU0:router(config-ipsla-sched)# recurring
Step 17
Specifies a time for the operation to start. The following
keywords are described:
start-time [hh:mm:ss {day | month day} | now | pending |
after hh:mm:ss]
Step 18
Example:
RP/0/RSP0/CPU0:router(config-ipsla-sched)#
start-time 01:00:00
•
(Optional) Use the pending keyword to configure
the operation to remain in a pending (unstarted) state.
The default value is inactive. If the start-time
command is not specified, no information is
collected until the start time is configured or a trigger
occurs that performs an immediate start.
•
(Optional) Use the now keyword to indicate that the
operation should start immediately.
•
(Optional) Use the after keyword and associated
arguments to specify the time after which the
operation starts collecting information.

Example:
RP/0/RSP0/CPU0:router# show ipsla statistics 432

Configuring the ICMP Path-jitter Operation
The IP SLA ICMP path-jitter operation provides hop-by-hop jitter, packet loss, and delay measurement
statistics in an IP network. The path-jitter operation functions differently than the standard UDP jitter operation,
which provides total one-way data and total round-trip data.
The ICMP path-jitter operation can be used as a supplement to the standard UDP jitter operation. For example,
results from the UDP jitter operation can indicate unexpected delays or high jitter values; the ICMP path-jitter
operation can then be used to troubleshoot the network path and determine if traffic is bottlenecking in a
particular segment along the transmission path.
