Control Of Trace Outputs - ELSA LANCOM Business Manuel De L'utilisateur

R94 ELSA LANCOM Business Internal
The online trace outputs are controlled by a newly implemented command in the remote
configuration, which is evaluated by the command interpreter and gives a direct
acknowledgment of the settings that have been made to the user. Changes to these
settings are effective immediately and generate or suppress the corresponding outputs
directly.
The online trace outputs are displayed by the remote configuration with a time delay with
respect to the actual event. The time stamp that is optionally displayed reflects the time
of the output, but not the time of the actual event. There is usually not a substantial
difference between these times; however, this point should always be considered when
analyzing the outputs.
All displays within the online trace outputs are shown in plain text so far as possible.
Because analysis of network protocols cannot completely avoid showing numerical
parameters and a trace system only makes sense when the information displayed is also
understood, exact descriptions of the trace information will be given below for all
protocols and functions.
If displays are activated for a protocol, the next output will overwrite the current system
prompt; every additional output will be preceded by a <Return> <LineFeed>. If the user
presses a key, the entire buffered input will be shown again with the current system
prompt. The user therefore receives visual feedback and inputs need not to be entered
"blind".

Control of Trace Outputs

Trace outputs are controlled by command line in the usual way. For this purpose, the
remote configuration has the command
syntax:
trace [key] [parameter] ...[parameter]
Key
Parameter
Keys and parameters must be separated by spaces. The keys are recognized by the
command interpreter only if they are unambiguous, i.e. they consist of one of the
characters listed above with no prefix or suffix. For the input of the symbolic protocol or
function name the input of an unambiguous prefix is sufficient, as usual.
Any number of keys and parameters may be entered in a command line, limited only by
the size of the line input buffer. The parameters are processed corresponding to the last
ELSA LANCOM Business
added; this has the following command

of individual protocols or functions.
´?´ display a help page
´+´ activate the trace outputs
´-´ deactivate the trace outputs
