N+1 Redundancy
Setting the syslog Debug Level
The nplus1set debugloglevel command sets the level of verboseness for the N+1 log
messages. The level can be set from 0 to 3, where 1 is the least verbose. The default
0 setting disables syslog messaging.
3000-slave(config)# nplus1 setdebugloglevel 1
N+1 Syslog Messages
Syslog messages are generated and sent to a log file on the syslog server configured
with the syslog-host command. These message are sent by a standalone N+1 slave
controller when an error condition occurs. A sample syslog message follows:
Oct 26 14:02:45 slave nplus1_Slave: <error message>
The list of syslog messages are as follows:
Error Message Description/Remedy
IP address not assigned.
Please run setup before using
nplus1
The command nplus1 start slave executed, but no IP
address exists for the controller. Run the setup
command on that controller and assign the controller a
static IP address.

Error reading the persistent record of configured
masters. Manually add the Master Controllers again.

Issues in initializing N+1 CLI.
ALERT: Software Mismatch:
Master (master_ip):
software_version Slave
(slave_ip): software_version
The Master Controller advertisement revealed a
software mismatch. While the version mismatch occurs,
the Master Controller cannot provide redundancy. Install
on the Master Controller the same software version as
the Slave Controller (or vice versa).
Copyback failed for master
controller: master_ip
Configuration of Master Controller changed while the
Slave was active, and the copyback failed. Remove the
new Master Controller configuration changes, failback
the Master Controller, and then perform the needed
configuration changes.
