Tcpdump Network Packet Capture Support - Mitel 6867i Administrator's Manual

• TFTP does not report transmission failure if the destination server is down. In this case,
the Support Information files are not sent.

TCPDUMP NETWORK PACKET CAPTURE SUPPORT

Tcpdump network packet capture functionality is natively available on the phones. By navigating
to the Advanced Settings > Capture page on the phone's Web UI, Administrators can
configure/perform the following:
Port: The port, ports, or range of ports from where the phone should capture traffic.
•
Timeout: The amount of time (in hours) the capture should extend until. The range is from
•
1 to 168 (7 days) and the default is 24 (1 day). The capture will automatically stop when
the timeout is met.
Get capture file: Allows you to save the capture file to the desired directory.
•
Start/Stop: Allows you to start/stop the tcpdump capture.
•
Notes:
1. Tcpdump capture functionality in this release supports phone side capture and
storage for troubleshooting issues that are of a consistent and reproducible nature.
For larger or long duration capture, Administrators are recommended to capture on
the network side using a hub or switch with port mirroring.
2. If attempting to capture packet data relating to an issue, Mitel recommends
Administrators perform multiple captures of the issue (if possible) to ensure the
respective packet data is collected.
3. The type of packets captured (TCP or UDP) is dependent on the transport protocol
configured on the phone.
