Monitoring LAN Traffic

Data for a LAN interfa ce can be gathe red by captu ring cu rrent in formati on an d placin g

it into a buffer. This data can then be displayed.

Configur ing the Monitor

To configure the parameters used in a capture, press [B] at the Traffic Monitor Menu

(or [C], [E], [B] from the Main Menu). This will display a screen similar to the fol-

lowing:

Information in this Display:

●Protocols – shows whether or not each LAN pr otocol is lo aded. (See Chapter 5.)

●Record ing – wil l be Active or Not Active, depending on whether or not a capture

is currently occurring.

●Buffer – wil l be Allocated if Reco rdin g is Active, or Not Allocated if Recording is

Not Active. If Allocated, the percentage of buffer filled and the number of e vents

will also be shown.

●LAN0 – identifies the LAN interface type, shows whether or not a capture is

occurring on the interface, and identifies the traffic type(s) to be monitored.

Each of the configurable parameters (items A–F) will toggle through the valid

settings when selec ted. Note, however, th at the changes will not be displayed on

the LAN0 line above until you press [F1] to refresh the displ ay .
