SBD Service and Processor Release Notes

Image

IPv4 Protocol Tunnel To SBD Service

This service will digest any IP packets that reach the MCG-101, whether they are set to the destination IP address of the MCG-101, or whether they were routed to the MCG-101 as a gateway, that match your selected protocol number. A generic list of protocols is here https://en.wikipedia.org/wiki/List_of_IP_protocol_numbers. The typical use case is to use the MCG-101 as a transparent IP layer service to route IP packets between two remote networks transparently. In this use case, you would set the MCG-101 as the gateway to your local network, and then send a packet to a non-local network address, which triggers your local system to forward the packet to the gateway, IE MCG-101, for delivery. The packet is consumed by the MCG-101 at network layer 3, and transparently transmitted via SBD including IP source, destination, protocol number, and payload, IE layer 3.

SBD To IPv4 Protocol Tunnel Service

This service will generate IP packets that reach the MCG-101 that contain a valid packet starting at Layer 3. Typically these packets are generated by another MCG-101 utilizing the IPv4 Protocol Tunnel to SBD Service. The incoming SBD packet will be routed to a tunnel interface that provide the Layer 2 MAC address lookups via arp to complete the packet, and then transmit it via the LAN bridge, which includes WiFi and Ethernet interfaces by default.

UDP To SBD Service

The UDP to SBD service will consume any payload data that is received on the defined UDP port, and transmit the data payload via SBD

SBD To UDP Service

The SBD to UDP service will broadcast on the defined UDP port any received SBD payload

TCP To SBD Service

The TCP to SBD service will consume any payload data that is received on the defined TCP port, and transmit the data payload via SBD

SBD To TCP Service

The SBD to TCP service will write SBD payload data to any host connected to the MCG-101 on the defined TCP port

RS232 To SBD Service

The RS232 to SBD service will packetize data based on the user defined End Of Packet delimiter, and escaped using the optional user defined Escape delimiter. For binary applications, you must use the Escape delimiter.

SBD To RS232 Service

The SBD to RS232 service will write SBD payload data to the RS232 port at the user defined baud rate, using the optional user defined Escape delimiter, and the user defined End Of Packet delimiter. For binary applications, you must use the Escape delimiter.

SNMP Service

Image SNMP Service, configurable to run on UDP or TCP. The SNMP service listens to a variety of GPS and Iridium broadcast messages, and some events that require polling. The behavior, source, and possible delay of each is noted below:

SNMP Service OIDSourceInstantaneous/DelayedBehavior
Real Time Clock1.3.6.1.4.1.38040.11.6.0GPSInstantaneous Report time acquired from GPS chipset after GPS signal has been acquired. Does require a GPS antenna to be connected
Link Quality1.3.6.1.4.1.38040.11.15.0 Iridium DPL PortInstantaneous Report last known signal level broadcasted from the Iridium DPL port. Does not force a query, but instead reports the signal level based on what would be displayed on an Iridium handset.
Lock/Unlock Status1.3.6.1.4.1.38040.11.13.0 Iridium Data PortDelayed, must query Iridium Data port Query the CULK status using an AT command that shares the single port between dial up data, SMS, and SBD. The Iridium Data port is first come first serve and this command can be denied if already busy
Error Status1.3.6.1.4.1.38040.11.16.0 Iridium Data PortDelayed, must query Iridium Data port Query the CMEE status using an AT command that shares the single port between dial up data, SMS, and SBD. The Iridium Data port is first come first serve and this command can be denied if already busy
Enable EMCON1.3.6.1.4.1.38040.11.7.0 Iridium Data PortDelayed, must query Iridium Data port Query and set the EMCON status using an AT command that shares the single port between dial up data, SMS, and SBD. The Iridium Data port is first come first serve and this command can be denied if already busy

Loading new firmware

Connect via WiFi or Ethernet and browse to http://192.168.10.1 and enter username superadmin, password webxaccess.

Go to System > Firmware > uncheck the "keep settings" field.

Select firmware saved on your computer and click "Update"

Setup

Configure PPP to auto start with any Ethernet traffic

Step 1

If you want PPPD to startup on boot then you need to enable "Enable on router startup". Otherwise the system will wait for either an XGate connection or for someone to push the connect button (ppp->status) before it will start up.

Image

Step 2

If you want PPPD to monitor traffic and connect on demand then enable the "on demand" feature. PPP will connect as soon as the unit boots, and then it will disconnect if there is no traffic for 60 seconds (configurable). It will reconnect when it sees traffic.

Image

Step 3

The firewall on the aurora is setup to block all traffic to the internet except for Xgate and Xweb, so it must be disabled if you want unrestricted access to the internet. To do this go to network->firewall->traffic rules and put check marks next to the first 6 rules (they are unchecked by default). This will enable all traffic, DNS, HTTP, HTTPS, and FTP traffic.

Image

Step 4

Reboot or power cycle the MCG-101.

Testing (optional)

Under services->ppp>status click the "connect" button to bring up PPP. This will bring up the PPP connection immediately. Note that the connection will be brought down in the idle time specified under services->ppp->settings->ppp
