CHAPTER 5: SERIAL PORT, HOST DEVICE AND USER CONFIG
5.1.7 SYSLOG
In addition to built-in logging and monitoring (which can be applied to serial-attached and network-attached management
accesses, as covered in Chapter 8), the console server can also be configured to support the remote syslog protocol on a per serial
port basis.
Select the Syslog Facility and Syslog Priority fields to enable logging of traffic on the selected serial port to a syslog server and to
appropriately sort and action those logged messages (for example, redirect them or send an alert email).
For example, if the computer attached to serial port 3 should never send anything out on its serial console port, the Administrator
can set the Syslog Facility for that port to local0 (local0 – local7 are meant for site local values), and the Syslog Priority to critical.
At this priority, if the console server syslog server does receive a message, it will automatically raise an alert. See Chapter 8 for
more.
5.1.8 NMEA STREAMING
The LES1600 can provide GPS NMEA data streaming from the internal GPS /cellular modem. This data stream presents as a serial
data stream on port 5 on the ACM models.
The Common Settings (baud rate, etc.) are ignored when configuring the NMEA serial port. You can specify the Fix Frequency (i.e.
this GPS fix rate determines how often GPS fixes are obtained). You can also apply all the Console Server Mode, Syslog and Serial
Bridging settings to this port.
NOTE: The NMEA Streaming menu item should display on the Serial & Network > Serial Port menu.
setfset -r lists all of the current feature set variables.
You look for the factory_opts variable, and then add 3g-gps to it.
For example, factory_opts=rs485,3g,ind.
To update it to 3g-gps, you do the following:
setfset -u factory_opts=rs485,3g-gps,ind.
Then run setfset -r again, and make sure you can see the update.
You can use pmshell, webshell, SSH, RFC2217 or RawTCP to get at the stream.
