Outputting Log Information To The Console - HP 5820X Switch Configuration Manual

Step 4: After log file info.log is created and file /etc/syslog.conf is modified, you must issue the
following commands to display the process ID of syslogd, kill the syslogd process, and restart syslogd
using the -r option to make the modified configuration take effect.
# ps -ae | grep syslogd
147
# kill -9 147
# syslogd -r &
NOTE:
Make sure that the syslogd process is started with the -r option on a Linux log host.
After the configurations, the system will be able to record log information into the log file.

Outputting log information to the console

Network requirements
Log information with a severity equal to or higher than informational will be output to the
•
console;
• The source modules are ARP and IP.

Configuration procedure
# Enable information center.
<Sysname> system-view
[Sysname] info-center enable
# Use channel console to output log information to the console (optional, console by default).
[Sysname] info-center console channel console
# Disable the output of log, trap, and debugging information of all modules on channel console.
[Sysname] info-center source default channel console debug state off log state off
trap state off
CAUTION:
As the default system configurations for different channels are different, you must disable the output of
log, trap, and debugging information of all modules on the specified channel—console in this
example—first and then configure the output rule as needed so that unnecessary information will not be
output.
# Configure the information output rule: allow log information of ARP and IP modules with severity
equal to or higher than informational to be output to the console. (The source modules allowed to
output information depend on the device model.)
[Sysname] info-center source arp channel console log level informational state on
