To display captured LAN data, press
[C]
at the Traffic Monitor Menu. The display will
be similar to the following:
Figure 19-9 LAN Capture Display
[C],[E],[C]
from Main Menu
The three numbers near the upper right identify (from left to right) the currently
selected frame, the lowest sequence number (
Num
– see below) in the current buffer,
and the highest sequence number in the current buffer.
Information in this Display:
●
Num
– a five-digit sequence number.
●
Time
– the time to the hundredth of a second since the first "event" in the current
buffer.
●
D
– the data direction:
I
(incoming) or
O
(outgoing), plus the LAN card number.
On monitors capable of displaying reverse video, outgoing frames will be dis-
played in reverse video.
●
Type
– the frame type:
IP
,
IPX
,
Bridge
, or
Unknown
.
●
Len
– length of the frame.
●
Data
– source MAC address, destination MAC address, frame type, and first 76
bytes of the frame, in hex.
Note that pressing
[F7]
will allow specification of an event (sequence) number to be
displayed, in case that number is not currently on the screen. (It must, however, be in
the buffer.)
The capture buffer can hold the first 76 bytes of each packet, up to 1000 packets. The
data is stored in a file named landata.out.
