Page: 479 / 686

Logging Function 479
modu-name
specifies the module name;
default
represents all the modules;
level
refers to the severity levels;
severity
specifies the severity level of information. The
information with the level below it will not be output.
channel-number
specifies the
channel number and
channel-name
specifies the channel name.
When defining the information sent to Telnet terminal or dumb terminal,
channel-number
or
channel-name
must be set to the channel that corresponds to
the Console direction.
Every channel has been set with a default record, whose module name is
default
and the module number is 0xffff0000. However, for different channels, the default
record may have different default settings of log, trap and debugging. When there is
no specific configuration record for a module in the channel, use the default one.
When there are more than one Telnet users or monitor users at the same time, some
configuration parameters should be shared among the users, such as module-based
filtering settings and severity threshold. When a user modifies these settings, it will be
reflected on other clients.
If you want to view the debugging information of some modules on the Switch, you
must select
debugging
as the information type when configuring information source,
meantime using the
debugging
command to turn on the debugging Switch of those
modules.
You can use the following commands to configure log information, debugging
information and the time-stamp output format of trap information.
Perform the following operation in System View.
Table 541 Configuring the Output Format of Time-stamp
4 Enabling terminal display function
To view the output information at the Telnet terminal or dumb terminal, you must first
enable the corresponding log, debugging and trap information functions at the
Switch.
For example, if you have set the log information as the information sent to the Telnet
terminal or dumb terminal, you need to use the
terminal logging
command to
enable the terminal display function of log information on the Switch, then you can
view the information at the Telnet terminal or dumb terminal.
Perform the following operation in User View.
