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 lines
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.
Note
Trunk status and alarms can be viewed from the
Status
menus of the Web Portal.
5.7.3
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 TMG3200. 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. Connect to the telecom platform
2a. Using telnet, for example: [root@TB005375 ]# telnet 172.31.1.1
or
2b. Using minicom, for example: [root@TB005375 ]# minicom
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
5.7.4
Wireshark (formerly called Ethereal)
Wireshark is useful for capturing both VoIP traffic as well as Streamserver packets (play/record
function).
