List box: On, Off
Default = Off
•
Off – Radio Link Control Frames (e.g. ACK frames) are never displayed.
• On – Radio Link Control Frames which pass the other monitoring filters are displayed
○ Bridge mode
○ Router mode
Tick boxes.
When RADIO interface is in the Promiscuous mode, the unit is capable to monitor (receive) the
frames which are transmitted in different operation modes (Bridge x Router) from the one set in
this unit. Although such frames cannot be fully analysed by the monitoring engine, their content
is displayed when the corresponding mode tick box is ticked. Note that only the applicable tick
box is visible, i.e. when Operating mode is Router, than Bridge mode tick box and vice versa.
○ Rx stream
Tick box.
When ticked, received stream mode frames are included in the monitoring output. Applies to
Bridge mode with Stream mode frame closing only. Warning : Stream mode traffic typically
consists of large number of short frames, hence excessive amount of monitoring data may be
generated. Note that TX frames in stream mode are not monitored.
○ Corrupted frames
Tick box.
Default = Ticked
When un-ticked, the corrupted ("header CRC error", "data CRC error", etc.) received frames are
not displayed. This may be useful when the communication in the channel is heavily disturbed
by interference or noise, resulting in „garbage“ messages which can make the monitoring output
difficult to read.
■ Interface specific parameters - ETH
○ ETH Headers
List box: On, Off
Default = Off
When On, the ETH header is included in the monitoring output. Otherwise only the IP packet is
displayed.
Note: When VLAN ID of VLAN packets is required to be displayed, ETH Headers must be "On".
○ Management traffic
List box: On, Off
Default=Off
When Off, datagrams to and from HTTPS, HTTP and SSH ports in this unit are not monitored.
This avoids monitoring loop under normal circumstances, i.e. when the on-line monitoring is
viewed on local PC connected via the ETH interface.
○ Advanced parameters:
User rule
The standard tcpdump program is used for ETH monitoring. An arbitrary user rule in tcpdump
syntax can be written in the text box. The rule is then added after the rules generated from
the filters set for the ETH interface on this web page.
Note: Not all general rules are supported. When unsupported or wrong syntaxes are used,
the warning (ETH monitoring terminated. Invalid tcpdump parameters?) will be displayed.
