Configuring TCP/IP settings

At the TCP/IP Configuration step, do the following:
  1. Review the Interface 1 settings on the IPv4 Settings tab, which include the temporary factory-shipped IP address.
  2. Assign the JACE a unique IPv4 address for the network you are installing it on. No other device on this network should use this same IP address. Include the appropriate subnet mask used by the network.
     
    CAUTION: If enabling more than one LAN port (applicable to LAN1, LAN2, and WiFi) then the IP address for each must be configured on different subnets, otherwise the ports will not function correctly. For example, with a typical “Class C” subnet mask of 255.255.255.0, setting Interface 1=192.168.1.99 and Interface 2=192.168.1.188 is an invalid configuration, as both addresses are on the same subnet.
     

    Alternatively, if the network supports DHCP, you can enable it (click DHCP Enabled). In this case, the IP Address and Subnet Mask fields become read only.

    Note that in general (for stability, static IP addressing is recommended over DHCP. If DHCP is preferred, an IP Address 'Reservation' should be entered for the controller in the DHCP Server. The controller IP address should not change.

     
    CAUTION: Do not enable DHCP unless you are certain that the network has DHCP servers! 
Otherwise, the controller may become unreachable over the network.
     
     
    NOTE: If the JACE-8000 platform is to be used to wirelessly connect to the enterprise network, DHCP should not be enabled here. In that event, the WiFi adapter in Client Mode will require use of the JACE DHCP feature. For more information, see the JACE-8000 WiFi Guide.
     
  3. Review, and if needed adjust other TCP/IP settings, which (in usual order of importance) include:
    • IPv4 Gateway — The IP address for the device that forwards packets to other networks or subnets.
       
      NOTE: The JACE only supports one gateway for all adapters. This includes the JACE-8000 WiFi Adapter in Client mode.
       
    • DNS Domain Name —  Enter the name of network domain, or if not applicable, leave blank.
    • DNSv4 Servers —  Click the Image add button for a field to enter the IPv4 address of one or more DNS servers.
    • Hostname — Default may be “localhost,” or enter another name you want to use for this host. If a hostname is entered, typically the name is unique for the domain.
       
      NOTE: In some installations, changing hostname may result in unintended impacts on the network, depending on how the DHCP or DNS servers are configured. If in doubt, leave hostname at default.
       
    • Hosts File — Click control to expand edit field. Format is a standard TCP/IP hosts file, where each line associates a particular IP address with a known host name. Each entry should be on an individual line. The IP address should be placed in the first column, followed by the corresponding host name. The IP address and the host name should be separated by at least one space.
    1. To add a line, click at the end of the last line and press Enter.
    2. Type in the required data on the new line.
      To return to see all TCP/IP settings, click the control to collapse the edit field when done.
     
    NOTE: The Undo Changes button resets all settings (all Interfaces) back to the original pre-step values.
     
  4. Click the Next button to go to the next step.
     
    NOTE: JACE-8000 controllers have two Ethernet ports, where “Interface 2” is available for configuring the secondary (LAN2) Ethernet port. By default, this port is disabled, that is without a “default” address. The intended usage for this port, as for the secondary LAN port, is as follows:
    • Isolating a “driver’s” Ethernet traffic from the primary (LAN1) interface, OR
    • Creating a private network by daisy chaining multiple IP devices off of the controller’s secondary LAN port.
       
      NOTE: This scenario requires that you configure the LAN2 port as a DHCP server in the DHCPDv4 Settings tab.
       
    • In some cases, LAN2 may be set up with a standard, fixed, IP address that is used only by a company’s service technician, when on site. This allows access to the JACE without disconnecting it from the customer’s network, or without connecting the technician’s service PC to the customer’s network (which might go against local IT security policies).

      If enabling LAN2, you must specify another (network) static IP address and the appropriate subnet mask, i.e. a different subnet mask for each enabled LAN port IP address.

    • The JACE does not provide IP routing or bridging operation between different Interfaces (LAN ports or WiFi).

     
     
    NOTE: The following step describes how to enable LAN2 Ethernet port if you want to use LAN2 for one of the reasons described above and how to configure DHCPDv4 if you want to use the enabled port as a DHCP server. Choose to perform the steps below depending on your requirements.
     
  5. Enable the secondary Ethernet port (Interface 2) as follows:
    1. Expand Interface 2.
    2. Select the Adapter Enabled check box.
  6. To setup the secondary Ethernet port (Interface 2) as a DHCP client:
    1. Select the Enabled check box on the IPv4Settings tab. Make sure that the DHCPDv4 is NOT enabled on the DHCPDv4 Settings tab.
  7. To setup the secondary Ethernet port (Interface 2) as a DHCP server:
    To use the secondary Ethernet port as a DHCP server, the port has to be configured with a static IP address. Verify this first by making sure that the DHCP check box is NOT selected on the IPv4 Settings tab.
    1. On the DHCPDv4 Settings tab, select the DHCPDv4 check box.
      This enables the DHCPv4 property fields.
    2. Configure property settings fields: the following are example values only:
      • Subnet: 192.168.111.0
      • Netmask: 255.255.255.0
      • Client range low: 192.168.111.15
      • Max. number of clients: 10
      Based on the example above, client IP pool is 192.168.111.15 to 192.168.111.24

      Type Value Description
      Default Lease Time 6 hours (default) Fixed duration (in hours, minutes, and seconds) for a DHCP IP address lease, before it expires the lease must be renewed.
      Max Lease Time 12 hours (default) Maximum duration (in hours, minutes, and seconds) for a DHCP IP address lease.
      Subnet   The subnet of IP addresses assigned by the DHCP server.
       
      CAUTION: Configure this to assign addresses on a different subnet than that used in other LAN or Access Point configurations, otherwise the ports will not function correctly.
       
      Netmask   The Netmask of IP addresses assigned by the DHCP Server.
      Client Range Low   Lowest IP address for the range. The order of assigning IPs from the Access Point DHCP is indeterminate.
       
      NOTE: The adapter IP should be in the same subnet, but not in the range of addresses defined here.
       
      Max Number of Clients 240 (default) Maximum number of clients that can attach at a given time.
    3. Under IPv4 Settings tab, enter the IPv4 address and subnet mask as shown below:
      • IPv4 Address: 192.168.111.1
      • IPv4 subnet mask: 255.255.255.0
       
      NOTE: Make sure that the secondary Ethernet port (Interface 2) IP address is outside the DHCP server’s client IP pool.
       
Save and reboot the controller for the network settings to take effect.
 
NOTE: To disable DHCP server running on the secondary Ethernet port (Interface 2): Under DHCPDv4 Settings Tab, uncheck the DHCPDv4 check box. Save & reboot the controller for the network settings to take effect.
