Configuring the ICMP Path-echo Operation
The IP SLA ICMP path-echo operation records statistics for each hop along the path that the IP SLA operation
takes to reach its destination. The ICMP path-echo operation determines the hop-by-hop response time between
a Cisco router and any IP device on the network by discovering the path using the traceroute facility.
The source IP SLA device uses traceroute to discover the path to the destination IP device. A ping is then
used to measure the response time between the source IP SLA device and each subsequent hop in the path to
the destination IP device.
The ICMP path-echo operation does not require the IP SLA Responder to be enabled.
Note
Depending on whether you want to configure and schedule a basic ICMP path-echo operation or configure
and schedule an ICMP path-echo operation with optional parameters, perform one of the following procedures:

• (Optional) Use the pending keyword to configure the

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.
