Configure the info-center loghost as follows:

1Enable the logging system.

[SW7750]info-center enable

2Set the host at 202.38.1.10 as info-center loghost, sets the severity threshold to

informational, the output language to English and allows the RSTP and IP modules

to output information.

[SW7750]info-center loghost 202.38.1.10 language english

[SW7750]info-center source rstp channel 5 log level informational

[SW7750]info-center source ip channel 4 log level informational

For the configurations at the host side, see “Configuring the Info-center Loghost”

on page 264.

Displaying and Debugging the Syslog Function

After performing the syslog configuration, execute the display command in all

views to display the configuration and to verify the effect of the configuration.

Execute the reset command in user view to clear the statistics of the syslog

module. Execute the debugging command in user view to debug the syslog

module.

Perform the following configuration in system view.

SNMP The Simple Network Management Protocol (SNMP) is used for transmitting

management information between any two nodes. In this way, network

administrators can easily search and modify the information on any node on the

network. They can also locate faults promptly and implement the fault diagnosis,

capacity planning, and report generating. SNMP adopts the polling mechanism

and provides the most basic function set. It is most applicable to the small-sized,

fast-speed, and low-cost environment. It only requires the unverified transport

layer protocol UDP, and is widely supported by many other products.
