streamExtractorModifier

streamExtractorModifier - replaces, in real time, UDP Video Client addresses in a monitored flow with the addresses of a monitoring device.

SYNOPSIS

streamExtractorModifier sub-command options

DESCRIPTION

The streamExtractorModifier command is used to replace, in real time, UDP Video Client addresses in a monitored flow with the addresses of a monitoring device. The packet modification performed (by AFM1000 stream extractor module) allows the video monitor to view many different streams, without ever having to change its addresses.

STANDARD OPTIONS
enable
true | false

This enables packet modification of Dest MAC, IPv4 Dest and UDP Dest ports. (default = false)

To enable a modifier, any one of the the filters must be enabled (MAC address, IP address, or TCP/UDP).

pattern

If enabled, use this pattern in the outgoing packet instead of the original.
(default ="00 00 00 00 00 00")

COMMANDS

The streamExtractorModifier command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.

streamExtractorModifier cget option

Returns the current value of the configuration option given by option. Option may have any of the values accepted by the streamExtractorModifierer command.

streamExtractorModifier config option

Modify the configuration options of the streamExtractorModifier. If no option is specified, returns a list describing all of the available options (see STANDARD OPTIONS) for streamExtractorModifierer. Specific errors are:

streamExtractorModifier get chasID cardID portID nlinePortID matcherType

streamExtractorModifier set chasID cardID portID inlinePortID matcherType

Sets the pattern matcher settings based on the filter direction (inlinePortId ) and pattern matcher type from IxTclHal to local IxHal.

Matcher type = the destination address type to be modified.
