Capture Wireshark Trace To Usb Flash Drive Through Telnet Command; Assigning A Vlan Id Using Dhcp - Polycom CX5100 Administrator's Manual

Polycom CX5100 Unified Conference Station for Microsoft Skype for Business - Administrator Guide
To capture the Wireshark trace to USB flash drive:
1 Format a USB flash drive to FAT32.
2 Set the capture length in the only parameter of the plcm_tcpdump_in_seconds.cfg file
between 1 to 300 seconds.
3 Copy the plcm_tcpdump_in_seconds.cfg file to a FAT32 formatted USB flash drive.
4 Connect the USB flash drive to the CX5100 system.
5 Turn on the CX5100 system.
The CX5100 system starts capturing the Wireshark trace to USB flash drive automatically. When the
time interval exceeds the capture length defined in the plcm_tcpdump_in_seconds.cfg file, the
CX5100 system stops capturing the trace.
The captured trace is stored in the USB flash drive as .pcap file.
Capture Wireshark Trace to USB Flash Drive through
Telnet Command
You can capture the Wireshark trace to USB flash drive using Telnet. The CX5100 unified conference station
allows you to capture the trace through Telnet when you enable the following parameters:
● diags.pcap.enabled
● diags.telnetd.enabled
To capture the Wireshark trace to USB flash drive through Telnet:
1 In the configuration file, edit the following parameters to:
 diags.pcap.enabled="1"
 diags.telnetd.enabled="1"
2 Copy the configuration file to a FAT32 formatted USB flash drive.
3 Connect the USB flash drive to the CX5100 system.
4 Turn on the CX5100 system.
5 From a computer connected to the same network, perform a telnet to the CX5100 unified
conference station.
6 Use the following commands to start capturing:
1 pcapFilterSet – Sets the capture filter to be used with the USB flash drive
2 pcapStart – Starts the capture to the USB flash drive
7 To stop capturing, use the pcapStop command.
The Wireshark trace capture is written out to a file with the naming convention
<MAC>-<date>-<time>.pcap and is placed in the root directory of the USB flash drive.

Assigning a VLAN ID Using DHCP

In deployments where is not possible or desirable to assign a virtual local area network (VLAN) statically in
the system's network configuration menu or use Cisco Discovery Protocol (CDP) or Link-Layer Discovery
