SiteManager GUI - System & UPLINK

  • Mode
    Select mode of the UPLINK interface. Possible choices depend on the interface type.
    Note: In SMS Wakeup mode, you must also enter SMS Wakeup Parameters below.
    Note: If you use PPPoE, you must also enter ISP settings below.
  • IP Address
    Enter the IP address of the UPLINK interface.
    Note : This is retrieved automatically for Mobile broadband interfaces and for Ethernet interfaces in DHCP or PPPoE mode.
  • Subnet Mask
    Enter the subnet mask of the UPLINK interface.
    Note : This is retrieved automatically for Mobile broadband interfaces and for Ethernet interfaces in DHCP or PPPoE mode.
  • Default Gateway
    Enter the default gateway. This is the IP address of the next router towards the Internet.
    Note : This is retrieved automatically for Mobile broadband interfaces and for Ethernet interfaces in DHCP or PPPoE mode.
  • Ethernet Settings
    Force ethernet link speed and duplex settings. This may be necessary if autonegotiation isn't supported by the attached equipment, or if the negotiated setting doesn't work reliably, e.g. because of noise or a mediocre cable. If you force the setting, you must make sure that the attached equipment runs with the same settings, of course.
  • MTU Mode
    Normally you should leave this at the default "Auto" setting in order to obtain best performance. However, in rare cases, some networks may require that you force a lower Ethernet packet size; in such a case, set this to "Manual" and enter the desired max packet size in the "MTU" field below.
  • Priority
    Set the priority of this UPLINK interface relative to the other UPLINK interface(s).
    As long as its Internet link is up, an interface with "First" priority will be used for outgoing connections. If the Internet link goes down, the SiteManager will fail-over to using the interface with "Second" priority until the link of the "First" priority interface is back up.
    In case both interfaces are set at the same priority (and both are up), the UPLINK interface will be used.
  • Probe Type
    Specify which probe methods to use to verify that the Internet link for this interface is working.
    By default, a positive response to any of the Ping and TCP probes will be taken as indication of a working connection.
    You may select to use only Ping or TCP for probing - or no probing at all.
  • Probe Hosts
    Enter one or preferably more IP addresses (separated by space) of hosts that the SiteManager should probe in turn (until the first one responds) to verify that the Internet link for this interface is working.
    Note: If you leave this field empty, the GateManager Server will be used as probe host.
  • Probe Port (TCP)
    Specify a port number to use for the TCP probe (if enabled).
    Note: No data will be transferred on the connection; it will only be attempted established and then immediately closed again.
    Also note that proxy servers may cause the connection attempt to be interpreted incorrectly (either as a false negative or a false positive).
  • Probe Interval A/B
    This specifies how often probes are sent to determine if the Internet link is working.
    Intervals are specified in seconds (in steps of 10), where 0 means never.
    Interval A is used when the priority of this interface is higher than, or equal to, the priority of the currently default interface (in the sense that "First" is higher priority than "Second").
    Interval B is used when the priority of this interface is lower than the priority of the currently default interface.
  • SIM PIN code (Mobile broadband interface only)
    If the SIM card is protected by a PIN code, enter it in this field.
    Note: If you enter an invalid PIN code, this field will automatically get cleared after the first try.
  • APN (Access Point Name, Mobile broadband interface only)
    Your SIM card provider will inform you which value to enter here.
    If you leave this field empty (or if the entered value doesn't work), all publicly known APNs for the provider of the installed SIM card will be tried (one at a time).
    To avoid using any other APN than the configured one (even in case it doesn't appear to work), you can prefix the APN with = (equal sign).
  • SMS Wakeup Parameters (Mobile broadband interface only)
    You must enter at least the mobile number of the inserted SIM card here when SMS-Wakeup mode is enabled. In this mode, the Mobile broadband interface will normally be offline, but it will go online and connect to the GateManager when it receives an SMS starting with the wakeup secret (see below). The SiteManager stays online as long as there is any activity from a GateManager or LinkManager, and then go offline until the next SMS wakeup is received.
    When the interface is offline it will have a 0.0.0.0 IP address and the UPLINK2 LED will show a "blink twice and pause" pattern.
    Note: After a reboot, the SiteManager must get an operational GateManager connection (via any interface) before it will enter the SMS-Wakeup mode.

    The mobile number must start with a + and the country prefix. It may be followed by optional parameters like this:
    + number [ / secret ][ ; id = value ]...
    The following optionals parameters can be used:

    • t= timeout (default 30 minutes)
      The timeout specifies the max time (in minutes) for the Mobile broadband interface to stay connected after any actual data traffic has been exchanged with a remote GateManager or LinkManager.
    • c= number (default empty)
      The number specifies the Service Center Address (mobile number) for sending SMS acknowledgement back to callers. This number is usually already stored in the SIM card by the provider, so there's normally no need to specify this.
    • a= ack (default on-demand )
      The ack specifies whether an acknowledgement SMS should be sent back to the sender of the wakeup SMS.
      Possible values are yes to always send an acknowledgement SMS, no to never send acknowledgement SMS, and on-demand which will only send an acknowledgement SMS if the wakeup secret is immediately followed by a question mark (?) or the word ack (for example: "Wakeup?" or "Wakeup ack").
    • / secret [backwards compatibility only]
      If used, the secret is moved into (overwrites) the SMS Wakeup Secret field.
    Example: A value of "+4512345678;c=+4530405060;a=y;t=10" specifies that the SMS number to call is +4512345678 (country code +45 is Denmark), an acknowledgement SMS is always sent (via Service Center at +4530405060), and the idle timeout is set to 10 minutes.
  • SMS Wakeup Secret (default "Wakeup")
    An SMS message will only activate the Mobile broadband interface if the beginning of the SMS text matches the secret (case is ignored).
    Notice that received SMS messages which matches the secret are automatically deleted; consequently, they are not readable by agents via the serial port or TCP requests. If an empty secret is used, any SMS will activate the Mobile broadband interface, and automatically deleted.
  • Init String (Mobile broadband interface only)
    If your Mobile broadband adapter needs a special initialization command, you can enter the string here (including the AT command prefix).
    Normally this field should be left blank, but some adapters and/or mobile network operators may require special commands for proper operation.
  • User Name
    Enter the user name (login name) for authenticating this SiteManager to the mobile broadband provider.
    Note: Most mobile broadband providers don't require authentication (other than possession of the SIM card), so usually you can just leave this field (and the Password field below) blank.
  • Password
    Enter the password for authenticating this SiteManager to the mobile broadband provider.
    Note: The CHAP authentication protocol is tried first. If the mobile broadband provider doesn't support CHAP, PAP is automatically used instead.
