Chapter 4: Serial Port, Device and User Configuration
4.1.6

Serial Bridging Mode

With serial bridging, the serial data on a nominated serial port on one Console Server is encapsulated into network packets
and then transported over a network to a second Console Server where is then represented as serial data. So the two Console
Servers effectively act as a virtual serial cable over an IP network.
One Console Server is configured to be the Server. The Server serial port to be bridged is set in Console Server mode with
either RFC2217 or RAW enabled (as described in Chapter 4.1.2 – Console Server Mode).
For the Client Console Server, the serial port to be bridged must be set in Bridging Mode:
• Select Serial Bridging Mode and specify the IP address of the Server Console Server and the TCP port address of the
remote serial port (for RFC2217 bridging this will be 5001-5048)
• By default the bridging client will use RAW TCP so you must select RFC2217 if this is the Console Server mode you have
specified on the server Console Server
• You may secure the communications over the local Ethernet by enabling SSH however you will need to generate and
upload keys (refer Chapter 14 – Advanced Configuration)
4.1.7

Syslog

In addition to inbuilt logging and monitoring (which can be applied to serial-attached and network-attached management
accesses, as covered in Chapter 7 - Alerts and Logging) the Console Server can also be configured to support the remote
syslog protocol on a per serial port basis:
• Select the Syslog Facility/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 (i.e. redirect them/ send alert email etc.)
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 meant 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.
