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
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. (Note that the source modules allowed to
output information depend on the device model.)
[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
