# Enable the information center.

<Switch> system-view

[Switch] info-center enable

# Disable the function of outputting information to log host channels.

[Switch] undo info-center source default channel loghost

# Configure the host whose IP address is 202.38.1.10 as the log host. Permit ARP and IP modules to

[Switch] info-center loghost 202.38.1.10 facility local4

[Switch] info-center source arp channel loghost log level informational debug state off trap

state off

[Switch] info-center source ip channel loghost log level informational debug state off trap

state off

2) Configure the log host:

The operations here are performed on SunOS 4.0. The operations on other manufacturers' Unix
operation systems are similar.

Step 1: Execute the following commands as the 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

local4.info /var/log/Switch/information

When you edit the file “/etc/syslog.conf”, note that:

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 allowed at the end of a file name.

z

The device name (facility) and received log information severity level specified in the file
“/etc/syslog.conf” must be the same as those corresponding parameters configured in the
commands info-center loghost and info-center source. Otherwise, log information may not be
output to the log host normally.
