Information Center Configuration Examples 1019
# 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
the channel console.
[Sysname] info-center source default channel console debug state off log state off trap state off
c
CAUTION: As the default system configurations for different channels are
different, you need to 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.
[Sysname] info-center source arp channel console log level informational state on
[Sysname] info-center source ip channel console log level informational state on
[Sysname] quit
# Enable the display of log information on a monitor terminal.
<Sysname> terminal monitor
% Current terminal monitor is on
<Sysname> terminal logging
% Current terminal logging is on
After the above configuration takes effect, if the specified module generates log
information, the information center automatically sends the log information to the
console and displays it on the console.
