Usually this parameter makes possible to activate/deactivate logging functionalities of meaningful events of the port as well as the detection and signalling of alarms in case of critical events.

The following table shows the available options and the related functionalities usable by the parameter:

Option	Meaning
D	Recording of the driver state changes and/or the meaningful events in Debug Log
S	Recording of the driver state changes and/or the meaningful events in the System Log
A	Periodic detection of possible alarms. The detected alarms can be displayed the command ALARM VIEW or by the analogous command available on the UTILITY of the LCD display on the front panel
L	On alarm detection, acoustic signal generation plus a message on the LCD display. This function depends on activation of alarms detection by the "A" option
T	Generation by the Agent SNMP of Abilis CPX of SNMP traps corresponding to any change of the driver state and/or occurring of meaningful events

Beside the already described options the following values are also allowed:

Option	Meaning
NO	It means that all the logging functionalities, alarms detection and generation, above mentioned, are disabled.
ALL	It means that all the logging functionalities, alarms detection and generation, above mentioned, are enabled.
+E	This option added to one or more of the previous ones, extends its (their) set of meaningful events. The value "ALL+E" activates all the options and extends the set of meaningful events. The value "NO+E" is meaningless so it is ignored.

Options can be combined together.

Some examples:

• setting "LOG:DS+E", activates the extended logging functions for Events Log and System Log
• setting "LOG:STA", activates the extended logging functions for System Log, SNMP traps generation and periodic detection of alarm states;

By using the characters "+" and "-" as prefix of one or more options is possible to add or delete one or more functionalities without setting from the scratch the value of the parameters.

Some examples:

• Suppose the current value of the parameter is "LOG:DSTA", by setting "LOG:-A", the periodic detection of eventual alarm states is removed, leaving unchanged all the remaining options; in such way the final value of the parameter will be "LOG:DST";
• Suppose the current value of the parameter is "LOG:ST", by setting "LOG:+DA", the logging function of the events on the Events Log and the periodic alarm detection are added to the already activated options; in such way the final value of the parameter will be "LOG:DSTA".

The changes made on this parameter are immediately activated, without the need of initialization commands.

This parameter allows to run-time activate/deactive TRFA functionalities.

When it is set to "NO", the port is running but saving traffic information is disabled.

When it is set to "YES", the port is running and the TRFA driver performs its activities, i.e. saving traffic information is enabled.

This parameter defines the maximum number of pair "IP port,IP address" in the TRFA address table.

The actual size of the internal database, as well as other relevant parameters, must are calculated by the driver using the present parameter, the TRFA-MODE: parameter and the IP-RESERVE: parameter.

This parameter defines the maximum number of PNG shell objects. This objects will be used creating PNG files for TRFA's HTML information page.

If you have a lot of interfaces with active TRFA and TRFA's HTML information page is created too slowly, then increase this value. Each PNG shell object gets about 400K memory.

This parameter activates the creation of a back-up copy of data files.

When it is set to "YES", the before replacing a ".DAT" file the TRFA driver makes a backup copy in a file with ".BAK" extension.

When it is set to "NO", the ".DAT" file is not backed-up.

This parameter defines the location of the directory where traffic data files are stored. It cannot be empty. It must be a physical full path in DOS notation, i.e. starting with a drive letter in the range ['A'..'Z'] and ending with the backslash ('\'). The maximum accepted working directory string length is 128 characters. Case is preserved and spaces are allowed, but strings holding spaces must be written between quotation marks (E.g.: "C:\My dir\").
