Installing and configuring TCP/IP software

Microsoft provides support for TCP/IP protocol with Windows. If your host PC does not already have TCP/IP protocol installed, you need to add it.

If you are installing a second Ethernet adapter to dedicate to the Ethernet TAP probe, you need to install a second instance of TCP/IP. In both instances, you bind the adapter to the TCP/IP protocol stack.

To install and configure TCP/IP, you need:

If you want other users to have access to the Ethernet TAP probe over the network, do not use the instructions in this section. Instead, see Connecting to network topic.

To add TCP/IP protocol to the host PC

  1. Add TCP/IP to the host PC.
    1. Select Start > Settings > Control Panel.

      The Control Panel window appears.

    2. In the Control Panel window, double-click the Network Connections icon.

      The Network Connections window appears.

    3. Right-click the connection name for which you want to install the TCP/IP protocol.

      A context menu appears.

    4. From the context menu, select Properties.

      The properties dialog box appears.

    5. Click the General tab.

      The General page appears.

    6. Check the Internet Protocol (TCP/IP) checkbox.
    7. Click Install.

      The Select Network Component Type dialog box appears.

    8. In the Select Network Component Type dialog box, select Protocol.
    9. Click Add.

      The Select Network Protocol dialog box appears.

    10. In the Network Protocol box, select Internet Protocol (TCP/IP).
    11. Click OK.

      The Select Network Protocol dialog box closes.

    12. In the properties dialog box, click OK.

      The TCP/IP protocol is added to the host PC.

  2. Configure TCP/IP to recognize the Ethernet Network Interface Card (NIC) used to connect to the Ethernet TAP probe.
    1. Select Start > Settings > Control Panel.

      The Control Panel window appears.

    2. In the Control Panel window, double-click the Network Connections icon.

      The Network Connections window appears.

    3. Right-click the connection name for which you want to install the TCP/IP protocol.

      The context menu appears.

    4. From the context menu, select Properties.

      The network connection properties dialog box appears.

    5. Click the General tab.

      The General page of the properties dialog box appears.

    6. From the General page, select the Internet Protocol (TCP/IP) protocol item.
    7. Click Properties.

      The Internet Protocol (TCP/IP) Properties dialog box appears.

    8. Select Use the following IP address option button.

      The IP address text boxes associated with this selected option appear.

  3. Specify an IP address and netmask.

    If the PC is already on an existing network, assign the second adapter an IP and netmask inconsistent with your network topology (use Class C if LAN is Class B, for example). This allows the PC to easily resolve communication with the LAN versus the Ethernet TAP probe. Valid possible internal-use IP addresses for each class are:

    A 10.0.0.0 - 10.255.255.255 255.0.0.0
    B 172.16.0.0 - 172.31.255.255 255.255.0.0
    C 192.168.0.0 - 192.168.255.255 255.255.255.0

    If the PC is to remain standalone, use the address and netmask listed below. These addresses simplify configuration.

    Address: 192.168.1.1

    Subnet mask: 255.255.255.0

  4. Confirm your settings, and close the Internet Protocol (TCP/IP) Properties window.
  5. When prompted, restart Windows.

If not prompted, restart Windows manually.

Note: Unless you want to password protect access, click Cancel when asked for a network password.
