[codec-numpackets number-of-packets] [codec-size number-of-bytes] [codec-interval
milliseconds] [advantage-factor value] [source-ip {ip-address | hostname}] [source-port
port-number] [control {enable | disable}]
Destination IPv4 IP address.
Destination IPv4 hostname.
Destination port number.
Specifies the codec type to be configured. Enables the generation of
estimated voice-quality scores in the form of Calculated Planning
Impairment Factor (ICPIF) and mean opinion score (MOS) values.
Codec type that should match the encoding algorithm that you are using for
VoIP transmissions.
The following codec-type keywords are available:
•
•
•
Configuring the codec type sets default values for the variables
codec-numpackets, codec-size, and codec-interval in this command.
(Optional) Specifies the number of packets to be transmitted per operation.
Number of packets. The range is from 1 to 60000. The default is 1000.
(Optional) Specifies the number of bytes in each packet transmitted. (Also
called the payload size or request size.)
Number of bytes in the payload. The range is from 16 to 16384. The default
varies by the codec.
(Optional) Specifies the interval (delay) between packets that should be used
for the operation.
Interpacket interval in milliseconds (ms). The range is from 4 to 60000. The
default is 20.
(Optional) Specifies the expectation factor to be used for ICPIF calculations.
This value is subtracted from the measured impairments to yield the final
ICPIF value (and corresponding MOS value).
Advantage factor. The range is from 0 to 20.
(Optional) Specifies the source IPv4 or IPv6 address. When a source IP
address is not specified, IP SLAs choose the IP address nearest to the
destination.
Source IPv4 IP address.
Source IPv4 hostname.
(Optional) Specifies the source port.
