Configuring Cisco IOS IP SLAs Operations

Source router
RTT (Round-trip time) = T4 (Time stamp 4) - T1 (Time stamp 1) -
An additional benefit of the two time stamps at the target device is the ability to track one-way delay,
jitter, and directional packet loss. Because much network behavior is asynchronous, it is critical to have
these statistics. However, to capture one-way delay measurements, you must configure both the source
router and target router with Network Time Protocol (NTP) so that the source and target are
synchronized to the same clock source. One-way jitter measurements do not require clock
synchronization.
Configuring IP SLAs Operations
This section does not include configuration information for all available operations as the configuration
information details are included in the Cisco IOS IP SLAs Configuration Guide. It includes only the
procedure for configuring the responder, as the switch includes only responder support.
