Using the Switch Trunk Debugging Tools

The ShoreGear switches have two tools that are helpful in troubleshooting trunks.

?

Trunk_debug_level is a switch setting that identifies trunk events from the switch?s

perspective. Since ShoreTel applications manipulate dialed digit strings for both

incoming and outgoing calls, the trunk debugger is typically used to validate the

traffic between the CO and the switch. The recommended trunk debug level is 4.

Step 1

Open a Telnet session and set debug on by typing:

trunk_debug_level=4

Step 2

When finished, turn off debug by typing:

trunk_debug_level=0

?

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.

NOTE

ShoreTel recommends that you use a Telnet interface that is capable of capturing

the output of the commands.

For IPBX switches, to turn on the D channel monitor:

Step 1

Open a Telnet session and type:

-> remConsoleConnect

-> remConsoleShell

Step 2

At the remCons> prompt, type:

remCons> pri_trace=10

remCons> pri_log=10

At this point, all D channel data is dumped to the screen.

Step 3

When you are finished capturing data, turn the monitor off by entering:

remCons> pri_trace=0

remCons> pri_log=0

Step 4

Exit the remote console shell by typing:

<cntrl>+d

Step 5

Exit the remote console by typing:

-> remConsoleDisconnect

For SG switches, to turn on the D channel monitor:

Step 1

Open a Telnet session and type:

Step 2

At the remCons> prompt, type:
