Protocol layers:
The check boxes shown under this heading are used to specify which protocol layers are includ-
ed in the protocol analyser trace. You can choose to generate a trace of the physical layer (Layer
1), the Link Layer (Layer 2) protocol, the Network Layer (Layer 3) protocol or any combination,
by checking or clearing the appropriate check-boxes. In addition, you may select XOT (X.25
over TCP/IP) tracing if this feature is included in your product.
IKE:
This checkbox is used to enable or disable the inclusion of IKE packets in the analyser trace
when using IPSec.
SNAIP:
This checkbox is used to enable or disable the inclusion of SNAIP packets in the analyser trace.
ISDN sources:
The group of check boxes shown under this heading are used to select the ISDN channels (D,
B1 and B2) that will be included in the trace. To include or exclude a specific LAPB or LAPD
instance from the trace ensure that the appropriate checkbox is checked or cleared respectively.
ASY sources:
The group of checkboxes shown under this heading is used to select the ASY ports that will be
included in the trace. To include a trace of commands issued to and responses from a particu-
lar port, ensure that the appropriate box is checked. The list of available ports will include the
physical ASY ports, internal “virtual ASY ports” (if present) and ports used by built-in GPRS/
PSTN modems.
Raw sync sources:
The group of checkboxes shown under this heading are is to select the synchronous sources
to be included in the trace. These include the ISDN channels D, B1 and B2 and any other syn-
chronous ports/protocols that your unit may include (e.g. physical port 1, 2, etc.). This feature
is especially useful for monitoring data transferred over ISDN when the higher layer protocol
does not record data in the trace (e.g.V.120).
Max I-PAK size:
The text-box labelled Max I-PAK Size allows you to specify the maximum number of bytes from
each X.25 Information Frame that will be included in the trace. Frames that are larger than this
value are truncated. Bear in mind that the larger this value, the quicker the “ANA.TXT” pseudo-
file (in which the trace output is stored), will become full so that the effective length of the
trace is reduced. The default value of 128 should be suitable in most cases.
PPP sources:
The group of checkboxes shown under this heading may be used to select the PPP sources to
be included in the trace.
IP sources:
The group of checkboxes shown under this heading may be used to select the IP sources to be
included in the trace. These sources include IP packets transmitted over PPP and ETH instances.
Ethernet sources:
The group of checkboxes shown under this heading may be used to select the Ethernet port
sources to be included in the trace.
IP Options:
The Trace Discarded Packets option will trace packets that have been discarded by any interface
and will also record the reason for the discard, regardless of any other analyser trace configura-
tion. Packets blocked by the firewall will also be logged to the trace.
