4.1.6 Serial Bridging Mode

With serial bridging, the serial data on a console server’s serial port is organized in network packets and transported over

a network to a second console server, effectively allowing the two console servers to act as a virtual serial cable on 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 (refer to 4.1.2 Console Server Mode).

For the Client console server, the serial port to be bridged must be set in Serial Bridging Mode:

• Select Serial Bridging Mode and specify the IP address of the Server console 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. You must select RFC2217 if this is the console server mode you have

speciﬁed on the server console.

• You may secure the communications over the local Ethernet by enabling SSH. However, you will need to generate and

upload keys (refer to section 14. Conﬁguration from the Command Line).

4.1.7 Syslog

In addition to built-in logging and monitoring (which can be applied to serial-attached and network-attached management

accesses, as covered in section 7. Alerts, Auto-Response 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 and Syslog Priority ﬁelds to enable trafﬁc logging on the syslog server’s selected. Doing so will

appropriately sort and create an action for those logged messages (e.g., redirect 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 create an

alert. See 7. Alerts, Auto-Response and Logging for more information.
