Analyser Management
Management-Analyser
The router can be configured to capture a trace of the data being transmitted and received
on the various interfaces. It is able to capture the layer 1, 2 and 3 protocol data and present
it in an easily read format. The Management-Analyser page has the following menu
options:
• Settings
• Trace
• PCAP (e.g. Wireshark) traces
Settings
Management-Analyser > Settings
Enable Analyser
This checkbox is used to enable or disable the analyser.
Maximum packet capture size
The number of bytes that are captured and stored for each packet. If the packet is bigger
than the configured size, the packet is truncated. Bear in mind that the larger this value,
the quicker the pseudo file “ana.txt” will become full so that the effective length of the
analyser trace is reduced.
Log Size
The maximum size of the pseudo file “ana.txt” that is used to store the captured data
packets. Once the maximum size is reached, the oldest captured data packets are
overwritten when new packets are captured.
The maximum value is 180Kb, but the data is compressed so more than 180Kb of trace data
will be captured.
Protocol layers
The checkboxes shown under this heading are used to specify which protocol layers are
captured and included in the analyser trace. You can choose to capture Layer 1 (physical /
PPP), Layer 2 (Laye protocol, the Network Layer (Layer 3) protocol or any combination, by
checking or clearing the appropriate checkboxes. In addition, you may select XOT (X.25
over TCP/IP) tracing if this feature is included on the router.
Enable IKE debug
This checkbox is used to enable or disable the inclusion of IKE packets in the analyser trace
when using IPsec.
Enable QMI trace
This checkbox is used to enable or disable the inclusion of data from the Qualcomm
Management Interface in the analyser trace.
Enable SNAIP trace
This checkbox is used to enable or disable the inclusion of SNAIP packet in the analyser
trace.
ISDN Sources
The checkboxes shown under this heading are used to select the ISDN channels (D, B1 and
B2) over which packets will be captured and included in the analyser trace.
LAPB Links
The checkboxes shown under this heading are used to select the LAPB links over which
packets will be captured and included in the analyser trace.
