7.7.2 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.
Note
Trunk status and alarms can be viewed from the Status menus of the Web Portal.
7.7.3 VoIP Traffic Capture
When troubleshooting VoIP related issues, you can use to use VoIP port mirroring to capture all
incoming and outgoing network packets from a VoIP network interface using the other VoIP interface. A
direct physical connection can be established with a host's Gigabit Ethernet interface and the other
VoIP interface. Wireshark or tcpdump is used on the host to capture network packets.
To capture VoIP Traffic from VoIP0 using VoIP1, do the following:
1. Connect the VoIP1 interface to the 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. Enter the following command:
mv88eMonitor 0x4 0x4 3
4. Start pcap capture on the server Ethernet port (either wireshark or tcpdump)
5. To stop the tracing:
mv88eMonitor 0 0 3
