Range of values / note
all
All interfaces
-
Recording mode of the WLAN inter‐
face
●
all-traffic
(access point only)
Note
In this mode the access point sends no more frames but
records all incoming frames. This means that the access point
is no longer reachable for other nodes and loses the
connected clients.
●
own-traffic
Note
In this case, the frames are recorded that are received and
sent by the device.
Exception: The frames dealt with directly by the hardware are
not displayed, for example hardware repetitions,
acknowledgment frames.
For information on identifiers of addresses and interfaces, refer to the section "Interface
identifiers and addresses (Page 29)".
Result
The function "remote capture" is enabled on the specified interface and the receive mode is
specified. When the device restarts, the function is disabled. With the command "
activate-
after-restart
" the function is enabled even after a restart.
Linking in the interface in Wireshark
Requirement:
● Wireshark V2.0.0 is installed on the PC.
● The PC and device must be reachable via IP (layer 3).
Procedure
To analyze the data traffic e.g. of the WLAN interface 1 in Wireshark, follow the steps below:
1. Activate the function
cli(remote-capture)# capture wlan 0/1 own-traffic
on
the interface.
2. Start Wireshark.
3. Click "Options" in the "Capture" menu. The window "Wireshark - Capture Interfaces" opens.
4. Click the "Manage Interfaces..." button on the "Input" tab. In the following dialog, click on
the "Remote Interfaces" tab.
5. To add the interface click on the Plus character in the "Remote Interfaces" tab.
6. In the following dialog enter the IPv4 address of the device for "Host" and 2002 for "Port".
7. Enable "Null authentication" for "Authentication" and click the "OK" button.
8. On the "Remote Interfaces" tab, the host and the interfaces on which the function "Remote
Capture" is enabled are displayed.
