Configuration procedure
1) Configure the switch:
# Enable the information center.
<Switch> system-view
[Switch] info-center enable
# Configure the host whose IP address is 202.38.1.10 as the log host. Permit all modules to output log
information with severity level higher than error to the log host.
[Switch] info-center loghost 202.38.1.10 facility local7
[Switch] info-center source default channel loghost log level errors debug state off trap
state off
2) Configure the log host:
Step 1: Execute the following commands as a super user (root user).
# mkdir /var/log/Switch
# touch /var/log/Switch/information
Step 2: Edit the file “/etc/syslog.conf” as the super user (root user) to add the following selector/action
pairs.
# Switch configuration messages
local7.info /var/log/Switch/information
Note the following items when you edit file “/etc/syslog.conf”.
z
A note must start in a new line, starting with a “#" sign.
z
In each pair, a tab should be used as a separator instead of a space.
z
No space is permitted at the end of the file name.
z
The device name (facility) and received log information severity specified in file “/etc/syslog.conf”
must be the same with those corresponding parameters configured in commands
info-center
loghost
and
info-center source
. Otherwise, log information may not be output to the log host
normally.
Step 3: After the log file “information” is created and the file “/etc/syslog.conf” is modified, execute the
following commands to view the process ID of the system daemon “syslogd”, stop the process, and then
restart the daemon "syslogd" in the background with the “-r” option.
# ps -ae | grep syslogd
147
# kill -9 147
# syslogd -r &
In case of Linux log host, the daemon “syslogd” must be started with the “-r” option.
After all the above operations, the switch can record information in the corresponding log file.
