Using Redundant Control Modules
Initial Configuration
Note
The
<facility-type>
is a string of the form:
user
,
kern
, or
local0
through
local7
.
These strings are reserved by the SYSLOG server daemon. for information on
how
<facility-type>
is used by the SYSLOG server, see the documentation for
your server’s
syslog.conf
file.
Here is an example:
5.
To activate the SYSLOG commands, use the
save active
command. Enter
yes
to activate the
changes.
Note
Up to four SYSLOG servers can be configured for each RS.

USING REDUNDANT CONTROL MODULES
The RS 8000/8600 supports the use of redundant Control Modules (CMs), one Control Module acts as the primary
CM, while the other Control Module acts as the backup CM. By default, the CM installed in slot CM is the primary
CM, while the CM installed in slot CM/1 is the backup CM. The purpose of the backup CM is to take over as the
primary CM in the event that the primary CM fails.
In normal operation, whenever changes are made to the primary CM’s Configuration file, the changes are copied to
the backup CM’s configuration file. In this way, if the primary CM fails, the backup CM has all the configuration
information necessary to take over as the primary CM. For instance, a static route is added to the RS 8000/8600. Notice
the messages displayed in the example when the change is saved to both the Active and Startup Configuration:
rs#
config
rs(config)#
system set syslog server 16.50.11.12
rs(config)#
system set syslog level info
rs(config)#
system set syslog facility local0
rs1(config)# ip add route 134.141.169.0/24 gateway 134.141.179.129
rs1(config)# save active
%SYS-I-ACTIVECFGTOBACKUP, active configuration updated on Backup CM
rs1(config)# save startup
Are you sure you want to overwrite the Startup configuration [no]? yes
%CONFIG-I-SAVED, configuration saved to Startup configuration.
%SYS-I-STARTUPCFGTOBACKUP, startup configuration file updated on Backup CM
rs1(config)#
