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
Facility
for that port to
local0
(
local0 .. local7
are for site
local values), and the
Priority
to
critical
. At this priority, if the
console server
syslog server does receive a
message, it will automatically raise an alert. Refer to
Chapter 7—Alerts & Logging.
4.1.8
NMEA Streaming
The LES1204A-3G, LES1300A and LES1400A can provide GPS NMEA data streaming from the internal
GPS /cellular modem. This data stream presents as a serial data steam on port 5 on the LES1204A-3G
model. For the LES1300A and LES1400A models with an internal cellular modem, the NMEA data stream
presents on ports 9/17/33/49 for the LES1308/16/32/48 models.
The Common Settings (baud rate etc.) are ignored when configuring the NMEA “serial port”. However 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.
You can also use
pmshell
,
webshell
,
SSH, RFC2217 or RawTCP
to get at the stream.
4.1.9
Cisco USB console connection
The LES1508A, LES1408A, LES1416A, LES1432A, LES1448A, LES1308A, LES1316A, LES1332A,
LES1348A, LES1208A-R2, LES1216A-R2, LES1232A and LES1248A-R2
console servers
support direct
USB2.0 connection to one or two Cisco USB console ports (in addition to the traditional RS-232 serial
console port connections).
With such a USB console connection users can send IOS commands through the USB console port
remotely (using a browser and the
console server’s
built-in AJAX terminal) or monitor messages from the
Cisco USB console ports and take rule book actions (using the
console server’s
built-in Auto-Response
capabilities).
For configuration and control these USB consoles are presented as new “serial ports”
on the
Serial &
Network: Serial Port
menu
. So for an LES1508A any Cisco USB console ports would present as Port 9
and 10.
Common Settings,
such baud rate, are ignored when configuring the Cisco USB “serial port”. However
you can apply all the Console Server Mode, Syslog and Serial Bridging settings to this port.
Note
:
The Cisco USB console is auto detected and the new “serial port” numbers are created. However
it must be manually configured on initial connection. Any subsequent USB console disconnection
is auto-detected. USB console re-connection on the same physical USB port
will also be auto-
detected, but only if the
console server
has been power cycled
.
