    IP address. The PR-6606 duplicates some or all of the UDP packets passing through it. The original packet is passed unchanged; if selected for duplication, it is duplicated and the duplicates sent to configured addresses.

  • Page 7: Features

    Installation Location To insure the PR-6606 will replicate the desired packets, the PR-6606 must be inserted in the network path between the original packet's source and original packet's destination. Furthermore, to prevent MAC table corruption in any layer-2 switches, the destination of a replicated packet must also reside on a different LAN port from the original source.

    Ethernet ports, similarly to a switch. The initial IP address may be entered using any terminal or terminal emulation software on a PC, or the default may be used if appropriate for your network. Any standard web browser may be used for configuration once the PR-6606 is configured with a valid IP address.

Configuration This model contains a serial interface to be used in initial setup (if needed). IF the default IP address is not appropriate for your LAN, connect a terminal to the serial port following the instructions in the configuration section.

    192.168.0.1 is appropriate for your local network, then plug it in and simply direct your web browser to the PR-6606 (using https if you've configured it to use https, otherwise use http:) without using a proxy and continue with configuration. If this address is not appropriate for your network, the IP address must be configured using the initial terminal method below.

    If the PC is in the default IP address range of the new hardware (192.168.0.x subnet), then a new, out-of-the-box unit is easily configured using this method. Start the hardware on the LAN, transfer a stored configuration file from the PC, and store it. When restarted, the PR-6606 will have the proper configuration.

    PR-6606 LAN port as the original destination or replicated destination. When the PR-6606 is replicating packets to a multicast or a broadcast address, the PR-6606 will not spoof the sender's MAC address, but instead will replace the original sender's MAC address with the PR-6606's MAC address, as is normal practice with multicast repeaters.

  • Page 32: Replication Rules Destinations Screen

    This screen is used to configure and display the destinations for replicated packets. The PR-6606 monitors all UDP packets passing through it. All packets received into any port of the PR-6606 are bridged unchanged and transmitted out the other ports of the PR-6606. Any UDP packets meeting user-defined selection criteria will be replicated and sent to one or more additional destinations.
