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
. It is then
represented on its serial port again as serial data. The two
console server
s effectively act as a virtual
serial cable over an IP network.
One
console server
is configured as the
Server
. Set the
Server
serial port to be bridged 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 bridge 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. 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. You will need to
generate and upload keys (refer to
Chapter 14— Advanced Configuration
).
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
Chapter
7—
Alerts and Logging
), you can also configure
the
console server
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 (that is, redirect
them/send alert email etc.).
