IpConfig/Promiscuous Registry Key
By default the network capture collects packets that specifically reference
either the JNIOR’s MAC address or IP address either as the source or
destination. This then excludes general broadcasts and any other unrelated
network traffic that the unit may see.
If you need to see all of the network traffic set this Registry key to
"enabled". This will enable Promiscuous Mode and the capture of all
network traffic that reaches the JNIOR. Note that changes in this setting
do not require a reboot and take effect immediately.
Network switches and routers generally optimize network traffic and
present devices with the subset of communications that are specifically
addressed for that destination. In Promiscuous Mode you will generally
receive additional broadcast packets and packets addressed to other possibly
non-existing devices which the switch or router has yet to locate and filter.
The network hub has been obsoleted by the network switch as traffic and
bandwidth optimization is a good thing. However the older technology in the
hub may be desirable if you need to analyze communications between two
other devices. The hub forwards all network traffic to all interconnected
devices. The JNIOR in Promiscuous Mode can then capture packet traffic
between the other devices. This may be very useful in debugging larger
multi-device systems. If you own a hub you should hang onto it as it can
be a useful debugging tool when used as a temporary network switch
