6.5.2 Line/Trunk Status (Tbshowls)
tbshowls (/tb/bin/release/[OS version]/)
tbshowls can be used to show trunk alarm and performance counters. The tool will check the trunk
status periodically to show the most updated trunk status. Users can use the up/down/left/right arrow
keys to show the performance data on different trunks. Use a-s-d-x to scroll and view other line
services.
Options 'G' and 'S' enable you to get and set the trunk interface parameters.
Option 'R' can be used to reset the performance counter value to zero.
It is also possible to allocate all line interfaces in different configurations. This is useful for DS3 and
OC3/STM-1 configurations, in order to help users understand the configuration.
6.5.3 VoIP Traffic Capture
When troubleshooting VoIP related issues, a direct Ethernet connection can be established between
the host's Gigabit Ethernet interface and the VoIP1 interface on the TMP6400. Wireshark is connected
on the Gigabit Ethernet interface on the host server.
To capture VoIP Traffic, do the following:
1. Connect VoIP1 interface to Ethernet port of a server
2. Telnet to TMP6400
3. Type this command:
mv88eMonitor 0x4 0x4 3 (Copies everything from VoIP0 to VoIP1) *
4. Start pcap capture on the server Ethernet port (either wireshark or tcpdump)
5. To stop the tracing:
mv88eMonitor 0 0 3
6.5.4 Wireshark (formerly called Ethereal)
Wireshark is useful for capturing both VoIP traffic as well as Streamserver packets (play/record
function).
This program is available at this site: www.wireshark.org
6.5.5 Tbstreamlisten
tb\apps\tbstreamlisten\release\[OS version]
This allows the recording of the raw data from a TDM stream. Please ask customer support for
instructions regarding this function.
