Switch Trunk Debug Tools
Trunk_debug_level is a switch setting that identifies trunk events from the switch’s perspective.
Because ShoreTel applications manipulate dialed digit strings for both incoming and outgoing calls, the
trunk debugger is typically used to validate the traffic between the Central office and the switch. The
recommended trunk debug level is 4.
1. Access the CLI shell, as described in CLI on page 95.
2. Enter the following command:
trunk_debug_level=4
3. When finished, turn off debug by typing:
trunk_debug_level=0
Creating a Tcpdump File
A tcpdump is a packet sniffer that operates off a command line. ShoreTel can use tcpdump output to
debug voicemail-enabled switch issues. Do not create tcpdump files without consulting ShoreTel
Technical Support.
To create a tcpdump file:
1. Access the CLI shell, as described in CLI on page 95.
2. Execute the following: tcpdump -C 10 -W 3 -w /var/log/tcpdump.pcap
This step captures ethernet traffic to the switch into ram.
3. After a brief period, press Ctrl-C.
This step terminates the capture and saves the result to the following directory path:
cp /var/log/tcpdump.* /ftproot
4. Submit the files to ShoreTel, as instructed by ShoreTel Technical Support.
Recording Audio from a Switch Port
You can capture audio output from a ShoreTel voice switch physical port (for example, a trunk port)
using a CLI command. Audio output is saved on the HQ or DVM server that controls the switch.
Note
The D channel monitor helps you monitor the D channel of a PRI span. To do this, turn on D channel
monitor of the switches. ShoreTel recommends using an SSH interface that is capable of capturing the
output of the commands.
