Capturing The Packets Via Remote Control; Capturing The Packets Via Ethernet Software; System Firmware - Yealink VC880 Administrator's Manual

Syntax
Host(s)
Logical Operations
Example: (src host 10.4.1.12 or src net 10.6.0.0/16) and tcp dst port range 200-10000 and dst net 10.0.0.0/8
Packets with the source IP address 10.4.1.12 or the source network 10.6.0.0/16, and the result is concatenated with
packets having destination TCP port range from 200 to 10000 and destination IP network 10.0.0.0/8.

Capturing the Packets via Remote Control

You can capture the packets via the remote control, and store the packets to the USB flash drive.
Before you begin
If you want to save packets to the USB flash drive, make sure a USB flash drive is connected, and the USB feature is
enabled.
Procedure
1. On the idle screen or during a call, long press
The monitor prompts "Onekey-capture has been turned on, press the Backspace key for 2s to turn off it".
2. Long press
for 2 seconds to stop capturing packets.
The packets are saved in the yealink.debug folder on your USB flash drive.

Capturing the Packets via Ethernet Software

Connect the Internet ports of your system and your computer to the same HUB, and then use Ethernet software to
capture the signal traffic.

System Firmware

The newly released firmware version may add new features. Therefore, Yealink recommends you to update the latest
firmware.
The following table lists the associated and latest firmware name for each system model (X is replaced by the actual
firmware version).
Description
Values: net, port, host, portrange
If no host(s) is specified, the "host" keyword is used.
For example: "src 10.1.1.1" is equivalent to "src host
10.1.1.1".
Values: not, and, or.
Negation ("not") has highest precedence. Alternation
("or") and concatenation ("and") have equal
precedence and associate left to right. For example:
"not tcp port 3128 and tcp port 23" is equivalent to
"(not tcp port 3128) and tcp port 23". "not tcp port
3128 and tcp port 23" is NOT equivalent to "not (tcp
port 3128 and tcp port 23)".
