Usage Guidelines
The udp-jitter command configures an IP SLAs UDP Plus operation. The UDP Plus operation is a
superset of the UDP echo operation. In addition to measuring the UDP round-trip time, the UDP Plus
operation measures per-direction packet loss and jitter. Jitter is an interpacket delay variance. Jitter
statistics are useful for analyzing traffic in a Voice over IP (VoIP) network.
You must configure the type of IP SLAs operation (such as User Datagram Protocol [UDP] jitter) before
you can configure any of the other parameters of the operation. To change the operation type of an
existing IP SLAs operation, you must first delete the IP SLAs operation (using the no ip sla global
configuration command) and then reconfigure the operation with the new operation type.
You must enable the IP SLAs responder on the target router before you can configure a UDP jitter
operation. Prior to sending an operation packet to the target router, IP SLAs send a control message to
the responder to enable the destination port. The control protocol is required when the target device is a
Cisco router that does not natively provide the UDP or TCP Connect service. If you disable the control
by using the control disable keyword combination with this command, you must define the IP address
of the source for the IP SLAs responder by using the ip sla responder udp-echo ipaddress command
on the destination device.
The default request packet data size for an IP SLAs UDP jitter operation is 32 bytes. Use the
request-data-size command to modify this value.
IP SLAs UDP jitter operations support IPv4 addresses.
When you specify the codec in the command syntax of the udp-jitter command, the standard
configuration options are replaced with codec-specific keywords and arguments. The codec-specific
command syntax is documented separately from the command syntax for the standard implementation
of the udp-jitter command.
This command does not require a license.

responder.
(Optional) Disables the sending of IP SLAs control messages to the IP SLAs
responder.
