is the WDS interface ID and can
be from 1 to 4. Configured WDS interfaces are shown on the

page.
3. Specify the following parameters:
•
Trace duration
: The time duration in seconds for the trace (range 10 to 3600).
•
Max trace file size
: The maximum allowed size for the trace file in KB (range 64 to
4096).
If you change either of these values, you must select
Save
before initiating a trace.
4. Select
Start Trace
.
The trace session will run for the specified duration. You can view the trace status in the
File trace status
section. Select
Refresh
to see updated trace time and file size values.
You can also select
Stop Trace
to stop a trace before the specified duration has elapsed.
Remote packet trace
Remote packet trace enables you to specify a remote port as the destination for packet
captures. This feature works in conjunction with the Wireshark network analyzer tool for
Windows. A packet trace server runs on the M210 and sends the captured packets via a TCP
connection to the Wireshark tool.
A Windows PC running Wireshark enables you to display, log, and analyze captured traffic.
When the remote trace mode is in use, the M210 does not store any captured data locally in its
file system.
Setting up Wireshark sessions
You can trace up to five interfaces on the M210 at the same time. However, you must start a
separate Wireshark session for each interface. You can configure the IP port number used for
connecting Wireshark to the M210. The default port number is 2002. The system uses five
consecutive port numbers starting with the configured port for the packet trace sessions.
If a firewall is installed between the Wireshark PC and the M210, these ports must be allowed
to pass through the firewall. The firewall must also be configured to allow the Wireshark PC to
initiate TCP connection to the M210.
To configure Wireshark to use the M210 as the source for captured packets, you must specify
the remote interface in the
Capture Options
menu. For example, to trace packets on an M210
with IP address 192.168.1.10 on radio 1 using the default IP port, specify the following
interface:
rpcap://192.168.1.10/radio1
To trace packets on the Ethernet interface of the M210 and on the default wireless community
(wlan0) using IP port 58000, start two Wireshark sessions and specify the following interfaces:
rpcap://192.168.1.10:58000/eth0
rpcap://192.168.1.10:58000/wlan0
